+ * Class WPML_Transient
+ *
+ * Due to some conflicts between cached environments (e.g. using W3TC) and the normal
+ * WP Transients API, we've added this class which should behaves almost like the normal
+ * transients API. Except for the fact that it is stored as normal options, so WP won't
+ * recognize/treat it as a transient.
