2 * Code is based on wmppp, wmload, wmtime, wmcp, and asbutton
3 * Author: Edward H. Flora <ehflora@ksu.edu>
4 *
5 * Contributors:
6 * Christian 'Greek0' Aichinger <Greek0@gmx.net>
7 * Did some code cleanup and fixed several memory leaks.
8 * Ralf Horstmann <ralf.horstmann@gmx.de>
9 * Added ability to load pixmaps at startup,
10 * without having to re-compile
11 * Michael Cohrs <camico@users.sourceforge.net>
12 * Added Tool Tips, and updated graphics
13 * Bruno Essmann <essmann@users.sourceforge.net>)
14 * Creator of wmpager
15 * Casey Harkins <charkins@cs.wisc.edu>
16 * Bug fix reading config file path - 3/6/99
17 * Added button-presses, and other - denoted by *charkins*
18 * Ben Cohen <buddog@aztec.asu.edu>
19 * original author of wmcp (et al.)
20 * Thomas Nemeth <tnemeth@multimania.com>
21 * contributor to wmcp
22 * Michael Henderson <mghenderson@lanl.gov>
23 * Application ideas, suggestions
24 * Ryan ?? <pancake@mindspring.com>
25 * Modified wmbutton to asbutton.
26 * Note: asbutton is a seperate program, not associated
27 * with wmbutton (just as wmbutton is not associated
28 * with wmcp)
29 * Jon Bruno
30 * Web Page Development
31 * The contributors listed above are not necessarily involved with the
32 * development of wmbutton. I'm listing them here partially as thanks for
33 * helping out, catching bugs in the code, etc.
