 	CHANGES:
 	---
+	10/10/2003 (Simon Law, sfllaw@debian.org)
+		* changed the parse_rcfile function to use getline instead of
+		  fgets.
+	10/14/2000 (Chris Gray, cgray@tribsoft.com)
+		* Removed a bug from parse_rcfile.  An extra
+		  newline would cause a segfault.
+	14/09/1998 (Dave Clark, clarkd@skyia.com)
+		* Updated createXBMfromXPM routine
+		* Now supports >256 colors
+	11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
+		* Removed a bug from parse_rcfile. You could
+		  not use "start" in a command if a label was
+		  also start.
+		* Changed the needed geometry string.
+		  We don't use window size, and don't support
+		  negative positions.
+	03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
+		* Added parse_rcfile2
+	02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
+		* Added -geometry support (untested)
+	28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
+		* Added createXBMfromXPM routine
+		* Saves a lot of work with changing xpm's.
 	02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
-		* changed the read_rc_file to parse_rcfile, as suggester by Marcelo E. Magallon
+		* changed the read_rc_file to parse_rcfile, as suggested 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,
