+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+# Exec with fallback
+
+[![Latest Stable Version](http://poser.pugx.org/rosell-dk/exec-with-fallback/v)](https://packagist.org/packages/rosell-dk/exec-with-fallback)
+[![Build Status](https://github.com/rosell-dk/exec-with-fallback/actions/workflows/php.yml/badge.svg)](https://github.com/rosell-dk/exec-with-fallback/actions/workflows/php.yml)
+[![Software License](http://poser.pugx.org/rosell-dk/exec-with-fallback/license)](https://github.com/rosell-dk/exec-with-fallback/blob/master/LICENSE)
+[![PHP Version Require](http://poser.pugx.org/rosell-dk/exec-with-fallback/require/php)](https://packagist.org/packages/rosell-dk/exec-with-fallback)
+[![Daily Downloads](http://poser.pugx.org/rosell-dk/exec-with-fallback/d/daily)](https://packagist.org/packages/rosell-dk/exec-with-fallback)
+
+Some shared hosts may have disabled *exec()*, but leaved *proc_open()*, *passthru()*, *popen()* or *shell_exec()* open. In case you want to easily fall back to emulating *exec()* with one of these, you have come to the right library.
+
+This library can be useful if you a writing code that is meant to run on a broad spectrum of systems, as it makes your exec() call succeed on more of these systems.
+
+## Usage:
+Simply swap out your current *exec()* calls with *ExecWithFallback::exec()*. The signatures are exactly the same.
+
+```php
+use ExecWithFallback\ExecWithFallback;
+$result = ExecWithFallback::exec('echo "hi"', $output, $result_code);
+// $output (array) now holds the output
+// $result_code (int) now holds the result code
+// $return (string | false) is now false in case of failure or the last line of the output
+```
+
+Note that while the signatures are the same, errors are not exactly the same. There is a reason for that. On some systems, a real `exec()` call results in a FATAL error when the function has been disabled. That is: An error, that cannot be catched. You probably don't want to halt execution on some systems, but not on other. But if you do, use `ExecWithFallback::execNoMercy` instead of `ExecWithFallback::exec`. In case no emulations are available, it calls *exec()*, ensuring exact same error handling as normal *exec()*.
+
+If you have `function_exists('exec')` in your code, you probably want to change them to `ExecWithFallback::anyAvailable()`
+
+## Installing
+`composer require rosell-dk/exec-with-fallback`
+
+## Implementation
+*ExecWithFallback::exec()* first checks if *exec()* is available and calls it, if it is. In case *exec* is unavailable (deactivated on server), or exec() returns false, it moves on to checking if *passthru()* is available and so on. The order is as follows:
+- exec()
+- passthru()
+- popen()
+- proc_open()
+- shell_exec()
+
+In case all functions are unavailable, a normal exception is thrown (class: Exception). This is more gentle behavior than real exec(), which on some systems throws FATAL error when the function is disabled. If you want exactly same errors, use `ExecWithFallback::execNoMercy` instead, which instead of throwing an exception calls *exec*, which will result in a throw (to support older PHP, you need to catch both Exception and Throwable. And note that you cannot catch on all systems, because some throws FATAL)
+
+In case none succeeded, but at least one failed by returning false, false is returned. Again to mimic *exec()* behavior.
+
+PS: As *shell_exec()* does not support *$result_code*, it will only be used when $result_code isn't supplied. *system()* is not implemented, as it cannot return the last line of output and there is no way to detect if your code relies on that.
+
+If you for some reason want to run a specific exec() emulation, you can use the corresponding class directly, ie *ProcOpen::exec()*.
+
+## Is it worth it?
+Well, often these functions are often all enabled or all disabled. So on the majority of systems, it will not make a difference. But on the other hand: This library is easily installed, very lightweight and very well tested.
+
+**easily installed**\
+Install with composer (`composer require rosell-dk/exec-with-fallback`) and substitute your *exec()* calls.
+
+**lightweight**\
+The library is extremely lightweight. In case *exec()* is available, it is called immediately and only the main file is autoloaded. In case all are unavailable, it only costs a little loop, amounting to five *function_exists()* calls, and again, only the main file is autoloaded. In case *exec()* is unavailable, but one of the others are available, only that implementation is autoloaded, besides the main file.
+
+**well tested**\
+I made sure that the function behaves exactly like *exec()*, and wrote a lot of test cases. It is tested on ubuntu, windows, mac (all in several versions). It is tested in PHP 7.0, 7.1, 7.2, 7.3, 7.4 and 8.0. And it is tested in different combinations of disabled functions.
+
+**going to be maintained**\
+I'm going to use this library in [webp-convert](https://github.com/rosell-dk/webp-convert), which is used in many projects. So it is going to be widely used. While I don't expect much need for maintenance for this project, it is going to be there, if needed.
+
+**Con: risk of being recognized as malware**
+There is a slight risk that a lazy malware creator uses this library for his malware. The risk is however very small, as the library isn't suitable for malware. First off, the library doesn't try *system()*, as that function does not return output and thus cannot be used to emulate *exec()*. A malware creator would desire to try all possible ways to get his malware executed. Secondly, malware creators probably don't use composer for their malware and would probably want a single function instead of having it spread over multiple files. Third, the library here use a lot of efford in getting the emululated functions to behave exactly as exec(). This concern is probably non-existant for malware creators, who probably cares more about the effect of running the malware. Lastly, a malware creator would want to write his own function instead of copying code found on the internet. Copying stuff would impose a chance that the code is used by another malware creator which increases the risk of anti malware software recognizing it as malware.

+## Do you like what I do?
+Perhaps you want to support my work, so I can continue doing it :)

+
+Just a bunch of handy methods for dealing with files and paths:
+
+
+- *FileExists::fileExists($path)*:\
+A well-behaved version of *file_exists* that throws upon failure rather than emitting a warning
+
+- *FileExists::fileExistsTryHarder($path)*:\
+Also well-behaved. Tries FileExists::fileExists(). In case of failure, tries exec()-based implementation
+
+- *PathValidator::checkPath($path)*:\
+Check if path looks valid and doesn't contain suspecious patterns
+
+- *PathValidator::checkFilePathIsRegularFile($path)*:\
+Check if path points to a regular file (and doesnt match suspecious patterns)

+
+*Detect / guess mime type of an image*
+
+Do you need to determine if a file is an image?<br>
+And perhaps you also want to know the mime type of the image?<br>
+
+&ndash; You come to the right library.
+
+Ok, actually the library cannot offer mime type detection for images which works *on all platforms*, but it can try a whole stack of methods and optionally fall back to guess from the file extension.
+
+The stack of detect methods are currently (and in that order):
+-  [This signature sniffer](https://github.com/rosell-dk/image-mime-type-sniffer) *Does not require any extensions. Recognizes popular image formats only*
+-  [`finfo`](https://www.php.net/manual/en/class.finfo.php) *Requires fileinfo extension to be enabled. (PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL fileinfo >= 0.1.0)*
+-  [`exif_imagetype`](https://www.php.net/manual/en/function.exif-imagetype.php) *Requires that PHP is compiled with exif (PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)*
+-  [`mime_content_type`](https://www.php.net/manual/en/function.mime-content-type.php) *Requires fileinfo. (PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)*
+
+Note that all these methods except the signature sniffer relies on the mime type mapping on the server (the `mime.types` file in Apache). If the server doesn't know about a certain mime type, it will not be detected. This does however not mean that the methods relies on the file extension. A png file renamed to "png.jpeg" will be correctly identified as *image/png*.
+
+Besides the detection methods, the library also comes with a method for mapping file extension to mime type. It is rather limited, though.
+
+## Installation
+
+Install with composer:
+```
+composer require rosell-dk/image-mime-type-guesser
+```
+
+## Usage
+
+To detect the mime type of a file, use `ImageMimeTypeGuesser::detect($filePath)`. It returns the mime-type, if the file is recognized as an image. *false* is returned if it is not recognized as an image. *null* is returned if the mime type could not be determined (ie due to none of the methods being available).
+
+Example:
+```php
+use ImageMimeTypeGuesser\ImageMimeTypeGuesser;
+$result = ImageMimeTypeGuesser::detect($filePath);
+if (is_null($result)) {
+    // the mime type could not be determined
+} elseif ($result === false) {
+    // it is NOT an image (not a mime type that the server knows about anyway)
+    // This happens when:
+    // a) The mime type is identified as something that is not an image (ie text)
+    // b) The mime type isn't identified (ie if the image type is not known by the server)
+} else {
+    // it is an image, and we know its mime type!
+    $mimeType = $result;
+}
+```
+
+For convenience, you can use *detectIsIn* method to test if a detection is in a list of mimetypes.
+
+```php
+if (ImageMimeTypeGuesser::detectIsIn($filePath, ['image/jpeg','image/png'])) {
+    // The file is a jpeg or a png
+}
+```
+
+The `detect` method does not resort to mapping from file extension. In most cases you do not want to do that. In some cases it can be insecure to do that. For example, if you want to prevent a user from uploading executable files, you probably do not want to allow her to upload executable files with innocent looking file extenions, such as "evil-exe.jpg".
+
+In some cases, though, you simply want a best guess, and in that case, falling back to mapping from file extension makes sense. In that case, you can use the *guess* method instead of the *detect* method. Or you can use *lenientGuess*. Lenient guess is even more slacky and will turn to mapping not only when dectect return *null*, but even when it returns *false*.
+
+*Warning*: Beware that guessing from file extension is unsuited when your aim is to protect the server from harmful uploads.
+
+*Notice*: Only a limited set of image extensions is recognized by the extension to mimetype mapper - namely the following: { apng, avif, bmp, gif, ico, jpg, jpeg, png, tif, tiff, webp, svg }. If you need some other specifically, feel free to add a PR, or ask me to do it by creating an issue.
+
+
+Example:
+```php
+$result = ImageMimeTypeGuesser::guess($filePath);
+if ($result !== false) {
+    // It appears to be an image
+    // BEWARE: This is only a guess, as we resort to mapping from file extension,
+    //         when the file cannot be properly detected.
+    // DO NOT USE THIS GUESS FOR PROTECTING YOUR SERVER
+    $mimeType = $result;
+} else {
+    // It does not appear to be an image
+}
+```
+
+The guess functions also have convenience methods for testing against a list of mime types. They are called `ImageMimeTypeGuesser::guessIsIn` and `ImageMimeTypeGuesser::lenientGuessIsIn`.
+
+Example:
+```php
+if (ImageMimeTypeGuesser::guessIsIn($filePath, ['image/jpeg','image/png'])) {
+    // The file appears to be a jpeg or a png
+}
+```

+
+
+Gets mime type of common *image* files by sniffing the file content, looking for signatures.
+
+The fact that this library limits its ambition to sniff images makes it light and simple. It is also quite fast. Most other sniffers iterates through all common signatures, however this library uses a mix of finite-state machine approach and iteration to achieve a good balance of speed, compactness, simplicity and readability.
+
+The library recognizes the most widespread image formats, such as GIF, JPEG, WEBP, AVIF, JPEG-2000 and HEIC.
+
+# Usage
+
+```php
+use \ImageMimeTypeSniffer\ImageMimeTypeSniffer;
+
+$mimeType = ImageMimeTypeSniffer::detect($fileName);  
+if (is_null($mimeType)) {
+  // mimetype was not detected, which means the file is probably not an image (unless it is a rare type)
+} else {
+  // It is an image, and we know the mimeType
+}
+```
+
+PS: An `\Exception` is thrown if the file is unreadable.
+
+# List of recognized image types:
+
+- application/psd
+- image/avif
+- image/bmp
+- image/gif
+- image/heic
+- image/jp2
+- image/jp20
+- image/jpeg
+- image/jpm
+- image/jpx
+- image/png
+- image/svg+xml
+- image/tiff
+- image/webp
+- image/x-icon
+- video/mj2
+
+TODO: image/heif
+
+
+# Alternatives
+
+I have created a library that uses this library as well as other methods (*finfo*, *exif_imagetype*, etc) for determining image type. You might want to use that instead, to cover all bases. It is available here: [image-mime-type-guesser](https://github.com/rosell-dk/image-mime-type-guesser).

+There are also other PHP mime type sniffers out there:

+[![Minimum PHP Version](https://img.shields.io/packagist/php-v/rosell-dk/locate-binaries)](https://php.net)
+
+Just a little class for locating binaries.
+You need `exec()`, `shell_exec()` or similar enabled for it to work. Otherwise, it will throw.
+
+Works on Linux, Windows and Mac.
+
+## Usage
+
+To locate installed `cwebp` binaries (found on Linux with `which -a`, falling back to `whereis -b`; on Windows found using `where`):
+```
+$cwebBinariesFound = LocateBinaries::locateInstalledBinaries('cwebp');
+```
+Note that you get an array of matches - there may be several versions of a binary on a system.
+
+The library also adds another method for locating binaries by peeking in common system paths, such as *usr/bin* and `C:\Windows\System32`
+However, beware that these dirs could be subject to open_basedir restrictions which can lead to warning entries in the error log. The other method is therefore best.
+
+Well warned, here it is the alternative, which you in some cases might want to fall back to after trying the first.
+```
+$imagickBinariesFound = LocateBinaries::locateInCommonSystemPaths('convert');
+```
+
+## Notes
+The library uses the [exec-with-fallback](https://github.com/rosell-dk/exec-with-fallback) library in order to be able to use alternatives to exec() when exec() is disabled.
+
+## Do you like what I do?
+Perhaps you want to support my work, so I can continue doing it :)

+WebP Convert is an MIT-licensed open source project. It is free and always will be.
+
+How is it financed then? Well, it isn't exactly. However, some people choose to support the development by buying the developer a cup of coffee, and some go even further, by becoming backers. Backers are nice folks making recurring monthly donations, and by doing this, they give me an excuse to put more work into the library than I really should.

+
+*Convert JPEG & PNG to WebP with PHP*
+
+This library enables you to do webp conversion with PHP. It supports an abundance of methods for converting and automatically selects the most capable of these that is available on the system.
+
+The library can convert using the following methods:
+- *cwebp* (executing [cwebp](https://developers.google.com/speed/webp/docs/cwebp) binary using an `exec` call)
+- *vips* (using [Vips PHP extension](https://github.com/libvips/php-vips-ext))
+- *imagick* (using [Imagick PHP extension](https://github.com/Imagick/imagick))
+- *gmagick* (using [Gmagick PHP extension](https://www.php.net/manual/en/book.gmagick.php))
+- *imagemagick* (executing [imagemagick](https://imagemagick.org/index.php) binary using an `exec` call)
+- *graphicsmagick* (executing [graphicsmagick](http://www.graphicsmagick.org/) binary using an `exec` call)
+- *ffmpeg* (executing [ffmpeg](https://ffmpeg.org/) binary using an `exec` call)
+- *wpc* (using [WebPConvert Cloud Service](https://github.com/rosell-dk/webp-convert-cloud-service/) - an open source webp converter for PHP - based on this library)
+- *ewwww* (using the [ewww](https://ewww.io/plans/) cloud converter (1 USD startup and then free webp conversion))
+- *gd* (using the [Gd PHP extension](https://www.php.net/manual/en/book.image.php))
+
+In addition to converting, the library also has a method for *serving* converted images, and we have instructions here on how to set up a solution for automatically serving webp images to browsers that supports webp.
+
+## Installation
+Require the library with *Composer*, like this:
+
+```text
+composer require rosell-dk/webp-convert
+```
+
+## Converting images
+Here is a minimal example of converting using the *WebPConvert::convert* method:
+
+```php
+// Initialise your autoloader (this example is using Composer)
+require 'vendor/autoload.php';
+
+use WebPConvert\WebPConvert;
+
+$source = __DIR__ . '/logo.jpg';
+$destination = $source . '.webp';
+$options = [];
+WebPConvert::convert($source, $destination, $options);
+```
+
+The *WebPConvert::convert* method comes with a bunch of options. The following introduction is a *must-read*:
+[docs/v2.0/converting/introduction-for-converting.md](https://github.com/rosell-dk/webp-convert/blob/master/docs/v2.0/converting/introduction-for-converting.md).
+
+If you are migrating from 1.3.9, [read this](https://github.com/rosell-dk/webp-convert/blob/master/docs/v2.0/migrating-to-2.0.md)
+
+## Serving converted images
+The *WebPConvert::serveConverted* method tries to serve a converted image. If there already is an image at the destination, it will take that, unless the original is newer or smaller. If the method cannot serve a converted image, it will serve original image, a 404, or whatever the 'fail' option is set to. It also adds *X-WebP-Convert-Log* headers, which provides insight into what happened.
+
+Example (version 2.0):
+```php
+require 'vendor/autoload.php';
+use WebPConvert\WebPConvert;
+
+$source = __DIR__ . '/logo.jpg';
+$destination = $source . '.webp';
+
+WebPConvert::serveConverted($source, $destination, [
+    'fail' => 'original',     // If failure, serve the original image (source). Other options include 'throw', '404' and 'report'
+    //'show-report' => true,  // Generates a report instead of serving an image
+
+    'serve-image' => [
+        'headers' => [
+            'cache-control' => true,
+            'vary-accept' => true,
+            // other headers can be toggled...
+        ],
+        'cache-control-header' => 'max-age=2',
+    ],
+
+    'convert' => [
+        // all convert option can be entered here (ie "quality")
+    ],
+]);
+```
+
+The following introduction is a *must-read* (for 2.0):
+[docs/v2.0/serving/introduction-for-serving.md](https://github.com/rosell-dk/webp-convert/blob/master/docs/v2.0/serving/introduction-for-serving.md).
+
+The old introduction (for 1.3.9) is available here: [docs/v1.3/serving/convert-and-serve.md](https://github.com/rosell-dk/webp-convert/blob/master/docs/v1.3/serving/convert-and-serve.md)
+
+
+## WebP on demand
+The library can be used to create a *WebP On Demand* solution, which automatically serves WebP images instead of jpeg/pngs for browsers that supports WebP. To set this up, follow what's described  [in this tutorial (not updated for 2.0 yet)](https://github.com/rosell-dk/webp-convert/blob/master/docs/v1.3/webp-on-demand/webp-on-demand.md).

+
+### Other projects using WebP Convert
+
+- [webp-convert-cloud-service](https://github.com/rosell-dk/webp-convert-cloud-service)
+A cloud service based on WebPConvert
+
+- [webp-convert-concat](https://github.com/rosell-dk/webp-convert-concat)
+The webp-convert library and its dependents as a single PHP file (or two)
+
+## Supporting WebP Convert
+Bread on the table don't come for free, even though this library does, and always will. I enjoy developing this, and supporting you guys, but I kind of need the bread too. Please make it possible for me to have both:

+## New in 2.9.0 (released 7 dec 2021, on my daughters 10 years birthday!)
+- When exec() is unavailable, alternatives are now tried (emulations with proc_open(), passthru() etc). Using [this library](https://github.com/rosell-dk/exec-with-fallback) to do it.
+- Gd is now marked as not operational when the needed functions for converting palette images to RGB is missing. Rationale: A half-working converter causes more trouble than one that is marked as not operational
+- Improved CI tests. It is now tested on Windows, Mac and with deactivated functions (such as when exec() is disabled)
+- And more (view closed issues [here](https://github.com/rosell-dk/webp-convert/milestone/25?closed=1)
+
+## New in 2.8.0:
+- Converter option definitions are now accessible along with suggested UI and helptexts. This allows one to auto-generate a frontend based on conversion options. The feature is already in use in the [webp-convert file manager](https://github.com/rosell-dk/webp-convert-filemanager), which is used in WebP Express. New method: `WebPConvert::getConverterOptionDefinitions()`
+- The part of the log that displays the options are made more readable. It also now warns about deprecated options.
+- Bumped image-mime-type guesser library to 0.4. This version is able to dectect more mime types by sniffing the first couple of bytes.
+- And more (view closed issues [here](https://github.com/rosell-dk/webp-convert/milestone/23?closed=1)
+
+## New in 2.7.0:
+- ImageMagick now supports the "near-lossless" option (provided Imagick >= 7.0.10-54) [#299](https://github.com/rosell-dk/webp-convert/issues/299)
+- Added "try-common-system-paths" option for ImageMagick (default: true). So ImageMagick will now peek for "convert" in common system paths [#293](https://github.com/rosell-dk/webp-convert/issues/293)
+- Fixed memory leak in Gd on very old versions of PHP [#264](https://github.com/rosell-dk/webp-convert/issues/264)
+- And more (view closed issues [here](https://github.com/rosell-dk/webp-convert/milestone/24?closed=1)
+
+## New in 2.6.0:
+- Introduced [auto-limit](https://github.com/rosell-dk/webp-convert/blob/master/docs/v2.0/converting/options.md#auto-limit) option which replaces setting "quality" to "auto" [#281](https://github.com/rosell-dk/webp-convert/issues/281)
+- Added "sharp-yuv" option and made it default on. [Its great](https://www.ctrl.blog/entry/webp-sharp-yuv.html), use it! Works in most converters (works in cwebp, vips, imagemagick, graphicsmagick, imagick and gmagick) [#267](https://github.com/rosell-dk/webp-convert/issues/267), [#280](https://github.com/rosell-dk/webp-convert/issues/280), [#284](https://github.com/rosell-dk/webp-convert/issues/284)
+- Bumped cwebp binaries to 1.2.0 [#273](https://github.com/rosell-dk/webp-convert/issues/273)
+- vips now supports "method" option and "preset" option.
+- graphicsmagick now supports "auto-filter" potion
+- vips, imagick, imagemagick, graphicsmagick and gmagick now supports "preset" option [#275](https://github.com/rosell-dk/webp-convert/issues/275)
+- cwebp now only validates hash of supplied precompiled binaries when necessary. This cuts down conversion time. [#287](https://github.com/rosell-dk/webp-convert/issues/287)
+- Added [new option](https://github.com/rosell-dk/webp-convert/blob/master/docs/v2.0/converting/options.md#cwebp-skip-these-precompiled-binaries) to cwebp for skipping precompiled binaries that are known not to work on current system. This will cut down on conversion time. [#288](https://github.com/rosell-dk/webp-convert/issues/288)

+# Development
+
+## Setting up the environment.
+
+First, clone the repository:
+```
+cd whatever/folder/you/want
+git clone https://github.com/rosell-dk/webp-convert.git
+```
+
+Then install the dev tools with composer:
+
+```
+composer install
+```
+
+If you don't have composer yet:
+- Get it ([download phar](https://getcomposer.org/composer.phar) and move it to /usr/local/bin/composer)
+- PS: PHPUnit requires php-xml, php-mbstring and php-curl. To install: `sudo apt install php-xml php-mbstring curl php-curl`
+
+
+## Unit Testing
+To run all the unit tests do this:
+```
+composer test
+```
+This also runs tests on the builds.
+
+
+Individual test files can be executed like this:
+```
+composer phpunit tests/Convert/Converters/WPCTest
+composer phpunit tests/Serve/ServeConvertedTest
+```
+
+
+## Coding styles
+WebPConvert complies with the [PSR-2](https://www.php-fig.org/psr/psr-2/) coding standard.
+
+To validate coding style of all files, do this:
+```
+composer phpcs src
+```
+
+To automatically fix the coding style of all files, using [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer), do this:
+```
+composer phpcbf src
+```
+
+Or, alternatively, you can fix with the use the [PHP-CS-FIXER](https://github.com/FriendsOfPHP/PHP-CS-Fixer) library instead:
+```
+composer cs-fix
+```
+
+## Running all tests in one command
+The following script runs the unit tests, checks the coding styles, validates `composer.json` and runs the builds.
+Run this before pushing anything to github. "ci" btw stands for *continuous integration*.
+```
+composer ci
+```
+
+## Generating api docs
+Install phpdox and run it in the project root:
+```
+phpdox
+```
+
+## Committing
+Before committing, first make sure to:
+- run `composer ci`
+
+## Releasing
+Before releasing:
+- Update the version number in `Converters/AbstractConverter.php` (search for "WebP Convert")
+- Make sure that ci build is successful
+
+When releasing:
+- update the [webp-convert-concat](https://github.com/rosell-dk/webp-convert-concat) library
+- consider updating the require in the composer file in libraries that uses webp-convert (ie `webp-convert-cloud-service` and `webp-express`)

+# The webp converters
+
+## The converters at a glance
+When it comes to webp conversion, there is actually only one library in town: *libwebp* from Google. All conversion methods below ultimately uses that very same library for conversion. This means that it does not matter much, which conversion method you use. Whatever works. There is however one thing to take note of, if you set *quality* to *auto*, and your system cannot determine the quality of the source (this requires imagick or gmagick), and you do not have access to install those, then the only way to get quality-detection is to connect to a *wpc* cloud converter. However, with *cwebp*, you can specify the desired reduction (the *size-in-percentage* option) - at the cost of doubling the conversion time. Read more about those considerations in the API.
+
+Speed-wise, there is too little difference for it to matter, considering that images usually needs to be converted just once. Anyway, here are the results: *cweb* is the fastest (with method=3). *gd* is right behind, merely 3% slower than *cwebp*. *gmagick* are third place, ~8% slower than *cwebp*. *imagick* comes in ~22% slower than *cwebp*. *ewww* depends on connection speed. On my *digital ocean* account, it takes ~2 seconds to upload, convert, and download a tiny image (10 times longer than the local *cwebp*). A 1MB image however only takes ~4.5 seconds to upload, convert and download (1.5 seconds longer). A 2 MB image takes ~5 seconds to convert (only 16% longer than my *cwebp*). The *ewww* thus converts at a very decent speeds. Probably faster than your average shared host. If multiple big images needs to be converted at the same time, *ewww* will probably perform much better than the local converters.
+
+[`cwebp`](#cwebp) works by executing the *cwebp* binary from Google, which is build upon the *libwebp* (also from Google). That library is actually the only library in town for generating webp images, which means that the other conversion methods ultimately uses that very same library. Which again means that the results using the different methods are very similar. However, with *cwebp*, we have more parameters to tweak than with the rest. We for example have the *method* option, which controls the trade off between encoding speed and the compressed file size and quality. Setting this to max, we can squeeze the images a few percent extra - without loosing quality (the converter is still pretty fast, so in most cases it is probably worth it).
+
+Of course, as we here have to call a binary directly, *cwebp* requires the *exec* function to be enabled, and that the webserver user is allowed to execute the `cwebp` binary (either at known system locations, or one of the precompiled binaries, that comes with this library).
+
+[`vips`](#vips) (**new in 2.0**) works by using the vips extension, if available. Vips is great! It offers many webp options, it is fast and installation is easier than imagick and gd, as it does not need to be configured for webp support.
+
+[`imagick`](#imagick) does not support any special webp options, but is at least able to strip all metadata, if metadata is set to none. Imagick has a very nice feature - that it is able to detect the quality of a jpeg file. This enables it to automatically use same quality for destination as for source, which eliminates the risk of setting quality higher for the destination than for source (the result of that is that the file size gets higher, but the quality remains the same). As the other converters lends this capability from Imagick, this is however no reason for using Imagick rather than the other converters. Requirements: Imagick PHP extension compiled with WebP support
+
+[`gmagick`](#gmagick) uses the *gmagick* extension. It is very similar to *imagick*. Requirements:  Gmagick PHP extension compiled with WebP support.
+
+[`gd`](#gd) uses the *Gd* extension to do the conversion. The *Gd* extension is pretty common, so the main feature of this converter is that it may work out of the box. It does not support any webp options, and does not support stripping metadata. Requirements: GD PHP extension compiled with WebP support.
+
+[`wpc`](#wpc) is an open source cloud service for converting images to webp. To use it, you must either install [webp-convert-cloud-service](https://github.com/rosell-dk/webp-convert-cloud-service) directly on a remote server, or install the Wordpress plugin, [WebP Express](https://github.com/rosell-dk/webp-express) in Wordpress. Btw: Beware that upload limits will prevent conversion of big images. The converter checks your *php.ini* settings and abandons upload right away, if an image is larger than your *upload_max_filesize* or your *post_max_size* setting. Requirements: Access to a running service. The service can be installed  [directly](https://github.com/rosell-dk/webp-convert-cloud-service) or by using [this Wordpress plugin](https://wordpress.org/plugins/webp-express/)
+
+[`ewww`](#ewww) is also a cloud service. Not free, but cheap enough to be considered *practically* free. It supports lossless encoding, but this cannot be controlled. *Ewww* always uses lossy encoding for jpeg and lossless for png. For jpegs this is usually a good choice, however, many pngs are compressed better using lossy encoding. As lossless cannot be controlled, the "lossless:auto" option cannot be used for automatically trying both lossy and lossless and picking the smallest file. Also, unfortunately, *ewww* does not support quality=auto, like *wpc*, and it does not support *size-in-percentage* like *cwebp*, either. I have requested such features, and he is considering... As with *wpc*, beware of upload limits. Requirements: A key to the *EWWW Image Optimizer* cloud service. Can be purchaced [here](https://ewww.io/plans/)
+
+[`stack`](#stack) takes a stack of converters and tries it from the top, until success. The main convert method actually calls this converter. Stacks within stacks are supported (not really needed, though).

+
+[cwebp](https://developers.google.com/speed/webp/docs/cwebp) is a WebP conversion command line converter released by Google. Our implementation ships with precompiled binaries for Linux, FreeBSD, WinNT, Darwin and SunOS. If however a cwebp binary is found in a usual location, that binary will be preferred. It is executed with [exec()](http://php.net/manual/en/function.exec.php).
+
+In more detail, the implementation does this:
+- It is tested whether cwebp is available in a common system path (eg `/usr/bin/cwebp`, ..)
+- If not, then supplied binary is selected from `Converters/Binaries` (according to OS) - after validating checksum
+- Command-line options are generated from the options
+- If [`nice`]( https://en.wikipedia.org/wiki/Nice_(Unix)) command is found on host, binary is executed with low priority in order to save system resources
+- Permissions of the generated file are set to be the same as parent folder
+
+### Cwebp options
+
+The following options are supported, besides the general options (such as quality, lossless etc):
+
+| Option                     | Type                      | Default                    |
+| -------------------------- | ------------------------- | -------------------------- |
+| autofilter                 | boolean                   | false                      |
+| command-line-options       | string                    | ''                         |
+| low-memory                 | boolean                   | false                      |
+| method                     | integer (0-6)             | 6                          |
+| near-lossless              | integer (0-100)           | 60                         |
+| size-in-percentage         | integer (0-100) (or null) | null                       |
+| rel-path-to-precompiled-binaries | string              | './Binaries'               |
+| size-in-percentage         | number (or null)          | is_null                    |
+| try-common-system-paths    | boolean                   | true                       |
+| try-supplied-binary-for-os | boolean                   | true                       |
+| use-nice                   | boolean                   | false                      |
+
+Descriptions (only of some of the options):
+
+#### the `autofilter` option
+Turns auto-filter on. This algorithm will spend additional time optimizing the filtering strength to reach a well-balanced quality. Unfortunately, it is extremely expensive in terms of computation. It takes about 5-10 times longer to do a conversion. A 1MB picture which perhaps typically takes about 2 seconds to convert, will takes about 15 seconds to convert with auto-filter. So in most cases, you will want to leave this at its default, which is off.
+
+#### the `command-line-options` option
+This allows you to set any parameter available for cwebp in the same way as you would do when executing *cwebp*. You could ie set it to "-sharpness 5 -mt -crop 10 10 40 40". Read more about all the available parameters in [the docs](https://developers.google.com/speed/webp/docs/cwebp)
+
+#### the `low-memory` option
+Reduce memory usage of lossy encoding at the cost of ~30% longer encoding time and marginally larger output size. Default: `false`. Read more in [the docs](https://developers.google.com/speed/webp/docs/cwebp). Default: *false*
+
+#### The `method` option
+This parameter controls the trade off between encoding speed and the compressed file size and quality. Possible values range from 0 to 6. 0 is fastest. 6 results in best quality.
+
+#### the `near-lossless` option
+Specify the level of near-lossless image preprocessing. This option adjusts pixel values to help compressibility, but has minimal impact on the visual quality. It triggers lossless compression mode automatically. The range is 0 (maximum preprocessing) to 100 (no preprocessing). The typical value is around 60. Read more [here](https://groups.google.com/a/webmproject.org/forum/#!topic/webp-discuss/0GmxDmlexek). Default: 60
+
+#### The `size-in-percentage` option
+This option sets the file size, *cwebp* should aim for, in percentage of the original. If you for example set it to *45*, and the source file is 100 kb, *cwebp* will try to create a file with size 45 kb (we use the `-size` option). This is an excellent alternative to the "quality:auto" option. If the quality detection isn't working on your system (and you do not have the rights to install imagick or gmagick), you should consider using this options instead. *Cwebp* is generally able to create webp files with the same quality at about 45% the size. So *45* would be a good choice. The option overrides the quality option. And note that it slows down the conversion - it takes about 2.5 times longer to do a conversion this way, than when quality is specified. Default is *off* (null)
+
+
+#### final words on cwebp
+The implementation is based on the work of Shane Bishop for his plugin, [EWWW Image Optimizer](https://ewww.io). Thanks for letting us do that!

+
+[wpc](https://github.com/rosell-dk/webp-convert-cloud-service) is an open source cloud service. You do not buy a key, you set it up on a server, or you set up [the Wordpress plugin](https://wordpress.org/plugins/webp-express/). As WebPConvert Cloud Service itself is based on WebPConvert, all options are supported.
+
+To use it, you need to set the `converter-options` (to add url etc).
+
+#### Example, where api-key is not crypted, on new API:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'api-version' => 1,     /* from wpc release 1.0.0 */
+            'url' => 'http://example.com/wpc.php',
+            'api-key' => 'my dog is white',
+            'crypt-api-key-in-transfer' => false
+        ]
+    ]    
+));
+```
+
+#### Example, where api-key is crypted:
+
+```php
+
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'api-version' => 1,
+            'url' => 'https://example.com/wpc.php',
+            'api-key' => 'my dog is white',
+            'crypt-api-key-in-transfer' => true
+        ],
+    ]
+));
+```
+
+In 2.0, you can alternatively set the api key and urls through through the *WPC_API_KEY* and *WPC_API_URL* environment variables. This is a safer place to store it.
+
+To set an environment variable in Apache, you can use the `SetEnv` directory. Ie, place something like the following in your virtual host / or .htaccess file (replace the key with the one you purchased!)
+
+```
+SetEnv WPC_API_KEY my-dog-is-dashed
+SetEnv WPC_API_URL https://wpc.example.com/wpc.php
+```
+
+
+#### Example, old API:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'url' => 'https://example.com/wpc.php',
+            'secret' => 'my dog is white',
+        ],
+    ]
+));
+```

+  <tr><th>Performance</th><td>~1300ms to convert a 40kb image</td></tr>
+  <tr><th>Reliability</th><td>Great (but, as with any cloud service, there is a risk of downtime)</td></tr>
+  <tr><th>Availability</th><td>Should work on <em>almost</em> any webhost</td></tr>
+  <tr><th>General options supported</th><td>`quality`, `metadata` (partly)</td></tr>
+  <tr><th>Extra options</th><td>`key`</td></tr>
+</table>
+
+EWWW Image Optimizer is a very cheap cloud service for optimizing images. After purchasing an API key, add the converter in the `extra-converters` option, with `key` set to the key. Be aware that the `key` should be stored safely to avoid exploitation - preferably in the environment, ie with  [dotenv](https://github.com/vlucas/phpdotenv).
+
+The EWWW api doesn't support the `lossless` option, but it does automatically convert PNG's losslessly. Metadata is either all or none. If you have set it to something else than one of these, all metadata will be preserved.
+
+In more detail, the implementation does this:
+- Validates that there is a key, and that `curl` extension is working
+- Validates the key, using the [/verify/ endpoint](https://ewww.io/api/) (in order to [protect the EWWW service from unnecessary file uploads, when key has expired](https://github.com/rosell-dk/webp-convert/issues/38))
+- Converts, using the [/ endpoint](https://ewww.io/api/).
+
+<details>
+<summary><strong>Roadmap</strong> 👁</summary>
+
+The converter could be improved by using `fsockopen` when `cURL` is not available - which is extremely rare. PHP >= 5.5.0 is also widely available (PHP 5.4.0 reached end of life [more than two years ago!](http://php.net/supported-versions.php)).
+</details>
+
+#### Example:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['gd', 'ewww'],
+    'converter-options' => [
+        'ewww' => [
+            'key' => 'your-api-key-here'
+        ],
+    ]
+));
+```
+In 2.0, you can alternatively set the api key by through the *EWWW_API_KEY* environment variable. This is a safer place to store it.
+
+To set an environment variable in Apache, you can use the `SetEnv` directory. Ie, place something like the following in your virtual host / or .htaccess file (replace the key with the one you purchased!)
+
+```
+	SetEnv EWWW_API_KEY sP3LyPpsKWZy8CVBTYegzEGN6VsKKKKA

+
+`gd` neither supports copying metadata nor exposes any WebP options. Lacking the option to set lossless encoding results in poor encoding of PNGs - the filesize is generally much larger than the original. For this reason, PNG conversion is *disabled* by default, but it can be enabled my setting `skip-pngs` option to `false`.

+Due to a [bug](https://bugs.php.net/bug.php?id=66590), some versions sometimes created corrupted images. That bug can however easily be fixed in PHP (fix was released [here](https://stackoverflow.com/questions/30078090/imagewebp-php-creates-corrupted-webp-files)). However, I have experienced corrupted images *anyway* (but cannot reproduce that bug). So use this converter with caution.

+WebP conversion with `imagick` is fast and [exposes many WebP options](http://www.imagemagick.org/script/webp.php). Unfortunately, WebP support for the `imagick` extension is pretty uncommon. At least not on the systems I have tried (Ubuntu 16.04 and Ubuntu 17.04). But if installed, it works great and has several WebP options.

+
+#### More on quality=auto
+Unfortunately, *libwebp* does not provide a way to use the same quality for the converted image, as for source. This feature is implemented by *imagick* and *gmagick*. No matter which conversion method you choose, if you set *quality* to *auto*, our library will try to detect the quality of the source file using one of these libraries. If this isn't available, it will revert to the value set in the *default-quality* option (75 per default). *However*, with the *wpc* converter you have a second chance: If quality cannot be detected locally, it will send quality="auto" to *wpc*.
+
+The bottom line is: If you do not have imagick or gmagick installed on your host (and have no way to install it), your best option quality-wise is to install *wpc* on a server that you do have access to, and connect to that. However,... read on:
+
+**How much does it matter?**
+The effect of not having quality detection is that jpeg images with medium quality (say 50) will be converted with higher quality (say 75). Converting a q=50 to a q=50 would typically result in a ~60% reduction. But converting it to q=75 will only result in a ~45% reduction. When converting low quality jpeg images, it gets worse. Converting q=30 to q=75 only achieves ~25% reduction.
+
+I guess it is a rare case having jpeg images in low quality. Even having middle quality is rare, as there seems to have been a tendency to choose higher quality than actually needed for web. So, in many cases, the impact of not having quality detection is minor. If you set the *default-quality* a bit low, ie 65, you will further minimize the effect.
+
+To determine if *webp-convert* is able to autodetect quality on your system, run a conversion with the *$logger* parameter set to `new EchoLogger()` (see api).
+
+#### More on the `converter-options` option
+You use this option to set options for the individual converters. Example:
+
+```
+'converter-options' => [
+    'ewww' => [
+        'key' => 'your-api-key-here'
+    ],
+    'wpc' => [
+        'url' => 'https://example.com/wpc.php',
+        'secret' => 'my dog is white'
+    ]
+]
+```
+Besides options that are special to a converter, you can also override general options. For example, you may generally want the `max-quality` to be 85, but for a single converter, you would like it to be 100 (sorry, it is hard to come up with a useful example).
+
+#### More on the `converters` option
+The *converters* option specifies the conversion methods to use and their order. But it can also be used as an alternative way of setting converter options. Usually, you probably want to use the *converter-options* for that, but there may be cases where it is more convenient to specify them here. Also, specifying here allows you to put the same converter method to the stack multiple times, with different options (this could for example be used to have an extra *ewww* converter as a fallback).
+
+Example:
+```
+WebPConvert::convert($source, $destination, [
+    'converters' => [
+        'cwebp',    
+        'imagick',
+        [
+            'converter' => 'ewww',
+            'options' => [            
+                'key' => 'your api key here',
+            ],
+        ],
+    ];
+)
+```
+In 2.0, it will be possible to use your own custom converter. Instead of the "converter id" (ie "ewww"), specify the full class name of your custom converter. Ie '\\MyProject\\BraveConverter'. The converter must extend `\WebPConvert\Convert\Converters\AbstractConverters\AbstractConverter` and you must implement `doConvert()` and the define the extra options it takes (check out how it is done in the build-in converters).
+
+### More on the `$logger` parameter
+WebPConvert and the individual converters can provide information regarding the conversion process. Per default (when the parameter isn't provided), they write this to `\WebPConvert\Loggers\VoidLogger`, which does nothing with it.
+In order to get this information echoed out, you can use `\WebPConvert\Loggers\EchoLogger` - like this:
+
+```php
+use WebPConvert\Loggers\EchoLogger;
+
+WebPConvert::convert($source, $destination, $options, new EchoLogger());
+```
+
+In order to do something else with the information (perhaps write it to a log file?), you can extend `\WebPConvert\Loggers\BaseLogger`.
+
+## Converters
+In the most basic design, a converter consists of a static convert function which takes the same arguments as `WebPConvert::convert`. Its job is then to convert `$source` to WebP and save it at `$destination`, preferably taking the options specified in $options into account.
+
+The converters may be called directly. But you probably don't want to do that, as it really doesn't hurt having other converters ready to take over, in case your preferred converter should fail.

+# The webp converters
+
+## The converters at a glance
+When it comes to webp conversion, there is actually only one library in town: *libwebp* from Google. All conversion methods below ultimately uses that very same library for conversion. This means that it does not matter much, which conversion method you use. Whatever works. There is however one thing to take note of, if you set *quality* to *auto*, and your system cannot determine the quality of the source (this requires imagick or gmagick), and you do not have access to install those, then the only way to get quality-detection is to connect to a *wpc* cloud converter. However, with *cwebp*, you can specify the desired reduction (the *size-in-percentage* option) - at the cost of doubling the conversion time. Read more about those considerations in the API.
+
+Speed-wise, there is too little difference for it to matter, considering that images usually needs to be converted just once. Anyway, here are the results: *cweb* is the fastest (with method=3). *gd* is right behind, merely 3% slower than *cwebp*. *gmagick* are third place, ~8% slower than *cwebp*. *imagick* comes in ~22% slower than *cwebp*. *ewww* depends on connection speed. On my *digital ocean* account, it takes ~2 seconds to upload, convert, and download a tiny image (10 times longer than the local *cwebp*). A 1MB image however only takes ~4.5 seconds to upload, convert and download (1.5 seconds longer). A 2 MB image takes ~5 seconds to convert (only 16% longer than my *cwebp*). The *ewww* thus converts at a very decent speeds. Probably faster than your average shared host. If multiple big images needs to be converted at the same time, *ewww* will probably perform much better than the local converters.
+
+[`cwebp`](#cwebp) works by executing the *cwebp* binary from Google, which is build upon the *libwebp* (also from Google). That library is actually the only library in town for generating webp images, which means that the other conversion methods ultimately uses that very same library. Which again means that the results using the different methods are very similar. However, with *cwebp*, we have more parameters to tweak than with the rest. We for example have the *method* option, which controls the trade off between encoding speed and the compressed file size and quality. Setting this to max, we can squeeze the images a few percent extra - without loosing quality (the converter is still pretty fast, so in most cases it is probably worth it).
+
+Of course, as we here have to call a binary directly, *cwebp* requires the *exec* function to be enabled, and that the webserver user is allowed to execute the `cwebp` binary (either at known system locations, or one of the precompiled binaries, that comes with this library).
+
+[`vips`](#vips) (**new in 2.0**) works by using the vips extension, if available. Vips is great! It offers many webp options, it is fast and installation is easier than imagick and gd, as it does not need to be configured for webp support.
+
+[`imagick`](#imagick) does not support any special webp options, but is at least able to strip all metadata, if metadata is set to none. Imagick has a very nice feature - that it is able to detect the quality of a jpeg file. This enables it to automatically use same quality for destination as for source, which eliminates the risk of setting quality higher for the destination than for source (the result of that is that the file size gets higher, but the quality remains the same). As the other converters lends this capability from Imagick, this is however no reason for using Imagick rather than the other converters. Requirements: Imagick PHP extension compiled with WebP support
+
+[`gmagick`](#gmagick) uses the *gmagick* extension. It is very similar to *imagick*. Requirements:  Gmagick PHP extension compiled with WebP support.
+
+[`gd`](#gd) uses the *Gd* extension to do the conversion. The *Gd* extension is pretty common, so the main feature of this converter is that it may work out of the box. It does not support any webp options, and does not support stripping metadata. Requirements: GD PHP extension compiled with WebP support.
+
+[`wpc`](#wpc) is an open source cloud service for converting images to webp. To use it, you must either install [webp-convert-cloud-service](https://github.com/rosell-dk/webp-convert-cloud-service) directly on a remote server, or install the Wordpress plugin, [WebP Express](https://github.com/rosell-dk/webp-express) in Wordpress. Btw: Beware that upload limits will prevent conversion of big images. The converter checks your *php.ini* settings and abandons upload right away, if an image is larger than your *upload_max_filesize* or your *post_max_size* setting. Requirements: Access to a running service. The service can be installed  [directly](https://github.com/rosell-dk/webp-convert-cloud-service) or by using [this Wordpress plugin](https://wordpress.org/plugins/webp-express/)
+
+[`ewww`](#ewww) is also a cloud service. Not free, but cheap enough to be considered *practically* free. It supports lossless encoding, but this cannot be controlled. *Ewww* always uses lossy encoding for jpeg and lossless for png. For jpegs this is usually a good choice, however, many pngs are compressed better using lossy encoding. As lossless cannot be controlled, the "lossless:auto" option cannot be used for automatically trying both lossy and lossless and picking the smallest file. Also, unfortunately, *ewww* does not support quality=auto, like *wpc*, and it does not support *size-in-percentage* like *cwebp*, either. I have requested such features, and he is considering... As with *wpc*, beware of upload limits. Requirements: A key to the *EWWW Image Optimizer* cloud service. Can be purchaced [here](https://ewww.io/plans/)
+
+[`stack`](#stack) takes a stack of converters and tries it from the top, until success. The main convert method actually calls this converter. Stacks within stacks are supported (not really needed, though).
+

+
+[cwebp](https://developers.google.com/speed/webp/docs/cwebp) is a WebP conversion command line converter released by Google. Our implementation ships with precompiled binaries for Linux, FreeBSD, WinNT, Darwin and SunOS. If however a cwebp binary is found in a usual location, that binary will be preferred. It is executed with [exec()](http://php.net/manual/en/function.exec.php).
+
+In more detail, the implementation does this:
+- It is tested whether cwebp is available in a common system path (eg `/usr/bin/cwebp`, ..)
+- If not, then supplied binary is selected from `Converters/Binaries` (according to OS) - after validating checksum
+- Command-line options are generated from the options
+- If [`nice`]( https://en.wikipedia.org/wiki/Nice_(Unix)) command is found on host, binary is executed with low priority in order to save system resources
+- Permissions of the generated file are set to be the same as parent folder
+
+### Cwebp options
+
+The following options are supported, besides the general options (such as quality, lossless etc):
+
+| Option                     | Type                      | Default                    |
+| -------------------------- | ------------------------- | -------------------------- |
+| autofilter                 | boolean                   | false                      |
+| command-line-options       | string                    | ''                         |
+| low-memory                 | boolean                   | false                      |
+| method                     | integer (0-6)             | 6                          |
+| near-lossless              | integer (0-100)           | 60                         |
+| size-in-percentage         | integer (0-100) (or null) | null                       |
+| rel-path-to-precompiled-binaries | string              | './Binaries'               |
+| size-in-percentage         | number (or null)          | is_null                    |
+| try-common-system-paths    | boolean                   | true                       |
+| try-supplied-binary-for-os | boolean                   | true                       |
+| use-nice                   | boolean                   | false                      |
+
+Descriptions (only of some of the options):
+
+#### the `autofilter` option
+Turns auto-filter on. This algorithm will spend additional time optimizing the filtering strength to reach a well-balanced quality. Unfortunately, it is extremely expensive in terms of computation. It takes about 5-10 times longer to do a conversion. A 1MB picture which perhaps typically takes about 2 seconds to convert, will takes about 15 seconds to convert with auto-filter. So in most cases, you will want to leave this at its default, which is off.
+
+#### the `command-line-options` option
+This allows you to set any parameter available for cwebp in the same way as you would do when executing *cwebp*. You could ie set it to "-sharpness 5 -mt -crop 10 10 40 40". Read more about all the available parameters in [the docs](https://developers.google.com/speed/webp/docs/cwebp)
+
+#### the `low-memory` option
+Reduce memory usage of lossy encoding at the cost of ~30% longer encoding time and marginally larger output size. Default: `false`. Read more in [the docs](https://developers.google.com/speed/webp/docs/cwebp). Default: *false*
+
+#### The `method` option
+This parameter controls the trade off between encoding speed and the compressed file size and quality. Possible values range from 0 to 6. 0 is fastest. 6 results in best quality.
+
+#### the `near-lossless` option
+Specify the level of near-lossless image preprocessing. This option adjusts pixel values to help compressibility, but has minimal impact on the visual quality. It triggers lossless compression mode automatically. The range is 0 (maximum preprocessing) to 100 (no preprocessing). The typical value is around 60. Read more [here](https://groups.google.com/a/webmproject.org/forum/#!topic/webp-discuss/0GmxDmlexek). Default: 60
+
+#### The `size-in-percentage` option
+This option sets the file size, *cwebp* should aim for, in percentage of the original. If you for example set it to *45*, and the source file is 100 kb, *cwebp* will try to create a file with size 45 kb (we use the `-size` option). This is an excellent alternative to the "quality:auto" option. If the quality detection isn't working on your system (and you do not have the rights to install imagick or gmagick), you should consider using this options instead. *Cwebp* is generally able to create webp files with the same quality at about 45% the size. So *45* would be a good choice. The option overrides the quality option. And note that it slows down the conversion - it takes about 2.5 times longer to do a conversion this way, than when quality is specified. Default is *off* (null)
+
+
+#### final words on cwebp
+The implementation is based on the work of Shane Bishop for his plugin, [EWWW Image Optimizer](https://ewww.io). Thanks for letting us do that!

+[wpc](https://github.com/rosell-dk/webp-convert-cloud-service) is an open source cloud service. You do not buy a key, you set it up on a server, or you set up [the Wordpress plugin](https://wordpress.org/plugins/webp-express/). As WebPConvert Cloud Service itself is based on WebPConvert, all options are supported.
+
+To use it, you need to set the `converter-options` (to add url etc).
+
+#### Example, where api-key is not crypted, on new API:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'api-version' => 1,     /* from wpc release 1.0.0 */
+            'url' => 'http://example.com/wpc.php',
+            'api-key' => 'my dog is white',
+            'crypt-api-key-in-transfer' => false
+        ]
+    ]    
+));
+```
+
+#### Example, where api-key is crypted:
+
+```php
+
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'api-version' => 1,
+            'url' => 'https://example.com/wpc.php',
+            'api-key' => 'my dog is white',
+            'crypt-api-key-in-transfer' => true
+        ],
+    ]
+));
+```
+
+In 2.0, you can alternatively set the api key and urls through through the *WPC_API_KEY* and *WPC_API_URL* environment variables. This is a safer place to store it.
+
+To set an environment variable in Apache, you can use the `SetEnv` directory. Ie, place something like the following in your virtual host / or .htaccess file (replace the key with the one you purchased!)
+
+```
+SetEnv WPC_API_KEY my-dog-is-dashed
+SetEnv WPC_API_URL https://wpc.example.com/wpc.php
+```
+
+
+#### Example, old API:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['cwebp', 'wpc'],
+    'converter-options' => [
+        'wpc' => [
+            'url' => 'https://example.com/wpc.php',
+            'secret' => 'my dog is white',
+        ],
+    ]
+));
+```

+
+EWWW Image Optimizer is a very cheap cloud service for optimizing images. After purchasing an API key, add the converter in the `extra-converters` option, with `key` set to the key. Be aware that the `key` should be stored safely to avoid exploitation - preferably in the environment, ie with  [dotenv](https://github.com/vlucas/phpdotenv).
+
+The EWWW api doesn't support the `lossless` option, but it does automatically convert PNG's losslessly. Metadata is either all or none. If you have set it to something else than one of these, all metadata will be preserved.
+
+In more detail, the implementation does this:
+- Validates that there is a key, and that `curl` extension is working
+- Validates the key, using the [/verify/ endpoint](https://ewww.io/api/) (in order to [protect the EWWW service from unnecessary file uploads, when key has expired](https://github.com/rosell-dk/webp-convert/issues/38))
+- Converts, using the [/ endpoint](https://ewww.io/api/).

+<summary><strong>Roadmap</strong> 👁</summary>
+
+The converter could be improved by using `fsockopen` when `cURL` is not available - which is extremely rare. PHP >= 5.5.0 is also widely available (PHP 5.4.0 reached end of life [more than two years ago!](http://php.net/supported-versions.php)).

+
+#### Example:
+
+```php
+WebPConvert::convert($source, $destination, [
+    'max-quality' => 80,
+    'converters' => ['gd', 'ewww'],
+    'converter-options' => [
+        'ewww' => [
+            'key' => 'your-api-key-here'
+        ],
+    ]
+));
+```
+In 2.0, you can alternatively set the api key by through the *EWWW_API_KEY* environment variable. This is a safer place to store it.
+
+To set an environment variable in Apache, you can use the `SetEnv` directory. Ie, place something like the following in your virtual host / or .htaccess file (replace the key with the one you purchased!)

+[imagewebp](http://php.net/manual/en/function.imagewebp.php) is a function that comes with PHP (>5.5.0), *provided* that PHP has been compiled with WebP support.
+
+`gd` neither supports copying metadata nor exposes any WebP options. Lacking the option to set lossless encoding results in poor encoding of PNGs - the filesize is generally much larger than the original. For this reason, PNG conversion is *disabled* by default, but it can be enabled my setting `skip-pngs` option to `false`.

+<summary><strong>Known bugs</strong> 👁</summary>
+Due to a [bug](https://bugs.php.net/bug.php?id=66590), some versions sometimes created corrupted images. That bug can however easily be fixed in PHP (fix was released [here](https://stackoverflow.com/questions/30078090/imagewebp-php-creates-corrupted-webp-files)). However, I have experienced corrupted images *anyway* (but cannot reproduce that bug). So use this converter with caution. The corrupted images look completely transparent in Google Chrome, but have the correct size.

+WebP conversion with `imagick` is fast and [exposes many WebP options](http://www.imagemagick.org/script/webp.php). Unfortunately, WebP support for the `imagick` extension is pretty uncommon. At least not on the systems I have tried (Ubuntu 16.04 and Ubuntu 17.04). But if installed, it works great and has several WebP options.
+
+See [this page](https://github.com/rosell-dk/webp-convert/wiki/Installing-Imagick-extension) in the Wiki for instructions on installing the extension.

+Stack implements the functionality you know from `WebPConvert::convert`. In fact, all `WebPConvert::convert` does is to call `Stack::convert($source, $destination, $options, $logger);`
+
+It has two special options: `converters` and `converter-options`. You can read about those in `docs/api/convert.md`
