/***********************************************************************
* Code is based on wmppp, wmload, wmtime, wmcp, and asbutton
* Author: Edward H. Flora <ehflora@ksu.edu>
*
* Contributors:
* Christian 'Greek0' Aichinger <Greek0@gmx.net>
* Did some code cleanup and fixed several memory leaks.
* Ralf Horstmann <ralf.horstmann@gmx.de>
* Added ability to load pixmaps at startup,
* without having to re-compile
* Michael Cohrs <camico@users.sourceforge.net>
* Added Tool Tips, and updated graphics
* Bruno Essmann <essmann@users.sourceforge.net>)
* Creator of wmpager
* Casey Harkins <charkins@cs.wisc.edu>
* Bug fix reading config file path - 3/6/99
* Added button-presses, and other - denoted by *charkins*
* Ben Cohen <buddog@aztec.asu.edu>
* original author of wmcp (et al.)
* Thomas Nemeth <tnemeth@multimania.com>
* contributor to wmcp
* Michael Henderson <mghenderson@lanl.gov>
* Application ideas, suggestions
* Ryan ?? <pancake@mindspring.com>
* Modified wmbutton to asbutton.
* Note: asbutton is a seperate program, not associated
* with wmbutton (just as wmbutton is not associated
* with wmcp)
* Jon Bruno
* Web Page Development
* The contributors listed above are not necessarily involved with the
* development of wmbutton. I'm listing them here partially as thanks for
* helping out, catching bugs in the code, etc.
