# This utility is used to generate a compact list of changes

+# Usage: pgcvslog [-d] [-h]
+# -d delete commits that include back branches
# -h is HTML output

+# 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
