Revision 1.6 - (hide annotations)
Sat Mar 10 02:54:39 2001 UTC (16 years, 7 months ago) by bertho
Branch: MAIN
CVS Tags: REL_1_1_1, REL_1_1_3, REL_1_1_2
Changes since 1.5: +8 -0 lines
- Fixed path problems. Cvsroot and module will always have a
  trailing '/' if they are not empty so that simple files
  can be addressed directly from the commandline. This also
  eases expansions.
- Implemented new features:
	* revisions can have custom text
	* background colors of boxes working
	* boxes can have shadow (looks nice)
	* imagemaps generate diff areas between revisions
- Several new config parameters to support above functionality.
