# Bzcmp/diff wrapped for bzip2,
# adapted from zdiff by Philippe Troin <phil@fifi.org> for Debian GNU/Linux.
# Bzcmp and bzdiff are used to invoke the cmp or the diff pro-
# gram on compressed files. All options specified are passed
# directly to cmp or diff. If only 1 file is specified, then
# the files compared are file1 and an uncompressed file1.gz.
# If two files are specified, then they are uncompressed (if
# necessary) and fed to cmp or diff. The exit status from cmp
# or diff is preserved.
