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 10/14/2000 (Chris Gray, cgray@tribsoft.com)
32 * Removed a bug from parse_rcfile. An extra
33 newline would cause a segfault.
34 14/09/1998 (Dave Clark, clarkd@skyia.com)
35 * Updated createXBMfromXPM routine
36 * Now supports >256 colors
37 11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
38 * Removed a bug from parse_rcfile. You could
39 not use "start" in a command if a label was
40 also start.
41 * Changed the needed geometry string.
42 We don't use window size, and don't support
43 negative positions.
44 03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
45 * Added parse_rcfile2
46 02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
47 * Added -geometry support (untested)
48 28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
49 * Added createXBMfromXPM routine
50 * Saves a lot of work with changing xpm's.
51 02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
52 * changed the read_rc_file to parse_rcfile, as suggested by
53 Marcelo E. Magallon
54 * debugged the parse_rc file.
55 30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
56 * Ripped similar code from all the wm* programs,
57 and put them in a single file.
