/* 
 *  faimtest.
 *
 *  The point of faimtest is twofold:
 *     - Test the functionality of libfaim.
 *     - Demonstrate the functionality of libfaim and how to use it.
 *
 *  It does the latter rather badly, and the first as best it can without a
 *  more realistic UI.  libfaim has a slightly different event model than
 *  many C programmers are used to, which is why I provide faimtest as
 *  documentation instead of attempting to explain how it works in English.
 *  If you're still in need of more guidance, see the source for the OSCAR
 *  "plugin" in gaim.  It does it nicely, and in a realistic situation. (Did
 *  I mention faimtest is a bit idealized?)
 *
 *  The faimtest code is very ugly.  Probably always will be.  
 *
 *  Note that faimtest does not do a lot of error checking, except perhaps
 *  on some libfaim funtions.  This is done for clarity, in hopes of
 *  making this crap ever so slighly more readable.
