Revision 1.1 - (hide annotations)
Sun Mar 4 01:38:23 2001 UTC (16 years, 8 months ago) by bertho
Branch: MAIN
CVS Tags: REL_1_1_0
File MIME type: text/plain
Major update of the code.
- Complete new method of getting the revision structure by directly
  reading the rcs/cvs file. This should also speed things a bit
  because no external program needs to be called anymore.
  This also means that "remote-graphs" are no longer a possible
  extension of the program. But, who cares.
- Implemented branch-kerning to save place. The images are now
  much smaller in width, dependent on the settings of the exterior
  margins.
- Fixed disjoint braches by reading the structure direct from the
  rcs/cvs file. The revision/branch structure is no longer determined
  from the revision numbers, but solely from the rcs/cvs file structure.
- Fixed display of branches with no revisions attached to them. These
  only have a tag describing the new branch.
