6 ** This file provides the framework for a plugin architecture.
7 **
8 ** Plugins will eventually be a way to provide added functionality
9 ** without having to patch the SquirrelMail source code. Have some
c27d5a49 10 ** patience, though, as the these funtions might change in the near
7b086a80 11 ** future.
12 **
13 ** Documentation on how to write plugins might show up some time.
