# curliff.pl - convert certain files in the Perl distribution that
# need to be in CR-LF format to CR-LF, or back to LF format (with the
# -r option).  The CR-LF format is NOT to be used for checking in
# files to the Perforce repository, but it IS to be used when making
# Perl snapshots or releases.
