# This utility is used to generate a compact list of changes
# for each release, bjm 2000-02-22
# Usage: pgcvslog [-h]
# Usage: pgcvslog [-d] [-h]
# -d delete commits that include back branches
# -h is HTML output
# This program basically takes a cvs log, groups it by commit timestamp
# and line number, then compares adjacent messages. If they have the same
# commit message, they are assumed to be part of the same commit and
# appear as one commit message with multiple file names
# All branches:
# cvs log -d'>1999-06-14 00:00:00 GMT' . > log
