-# Perl filter to handle pre-commit checking of files. This program
-# records the last directory where commits will be taking place for
-# use by the log_accum.pl script. For new files, it forces the
-# existence of a RCS "Id" keyword in the first ten lines of the file.
-# For existing files, it checks version number in the "Id" line to
-# prevent losing changes because an old version of a file was copied
-# into the direcory.
-#
-# Possible future enhancements:
-#
-# Check for cruft left by unresolved conflicts. Search for
-# "^<<<<<<<$", "^-------$", and "^>>>>>>>$".
-#
-# Look for a copyright and automagically update it to the
-# current year. [[ bad idea! -- woods ]]
