/* pywmgeneral.c
 *
 * Python bindings to some of the most important functions in the widely used
 * wmgeneral.c. Also some added functions. The rc file parser is removed since
 * Python provide better facilities for this.

 * History:
 *
 * 2024-09-08 Fredrick W. Warren
 * Ported from python 2 to python 3
 *
 * 2003-06-24 Kristoffer Erlandsson
 * Added some additional event handling.
 *
 * 2003-06-16 Kristoffer Erlandsson
 * Added checkForMouseClick to make catching of mouse clicks available from
 * Python.
 *
 * 2003-06-14 Kristoffer Erlandsson
 * Finished support for "everything" included in wmgeneral by default.
 *
 * 2003-06-13 Kristoffer Erlandsson
 * File created made most of the pure wrapper functions and xpm inclusion.
 *
 *
 *
 * Thanks to Martijn Pieterse for createing the original wmgeneral.c
