# 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.
