+# 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_accumulate script.  For new file, it forcing 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.
