Revision 1.5 - (hide annotations)
Wed Oct 20 22:03:36 2004 UTC (13 years, 1 month ago) by bertho
Branch: MAIN
Changes since 1.4: +1 -0 lines
Added patch from Gordon Hollingworth <Gordon.Hollingworth {at} TTP.com> to use
mergepoints as implemented by CVSNT. Adapted the patch to enable both
tag-detected merges and mergepoints to be shows at the same time.
