02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|

* changed the read_rc_file to parse_rcfile, as suggester by Marcelo E. Magallon
|
||
|
|
* debugged the parse_rc file.
|
||
|
|
30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
|
||
|
|
* Ripped similar code from all the wm* programs,
|
||
|
|
and put them in a single file.
