26 CHANGES:
27 ---
28 10/10/2003 (Simon Law, sfllaw@debian.org)
29 * changed the parse_rcfile function to use getline instead of
30 fgets.
31 14/09/1998 (Dave Clark, clarkd@skyia.com)
32 * Updated createXBMfromXPM routine
33 * Now supports >256 colors
34 11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
35 * Removed a bug from parse_rcfile. You could
36 not use "start" in a command if a label was
37 also start.
38 * Changed the needed geometry string.
39 We don't use window size, and don't support
40 negative positions.
41 03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
42 * Added parse_rcfile2
43 02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
44 * Added -geometry support (untested)
45 28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
46 * Added createXBMfromXPM routine
47 * Saves a lot of work with changing xpm's.
48 02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
49 * changed the read_rc_file to parse_rcfile, as suggested by
50 Marcelo E. Magallon
51 * debugged the parse_rc file.
52 30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
53 * Ripped similar code from all the wm* programs,
54 and put them in a single file.
