pgcvslog isn't useful anymore, either. 

See git_topo_order instead.

# src/tools/pgcvslog
# This utility is used to generate a compact list of changes
# for each release, bjm 2000-02-22
# Usage: pgcvslog [-d] [-h]
# -d delete commits that include back branches
# -h is HTML output
# "-d" is useful for generating release notes for major releases
# 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
#
# HEAD:
# cvs log -d'>2000-05-29 00:00:00 GMT' -b .
#
# Branch:
# cvs log -d'>2000-05-29 00:00:00 GMT' -rREL8_0_STABLE .
#
# Date range
# cvs log -d'2005-05-08<2005-05-29' -rREL8_0_STABLE .
#
# To find branch time, look for "branches:" tag in CVS commit logs
# e.g. "branches: 1.398.4;" matches "REL8_0_STABLE: 1.398.0.4".
