# Bzcmp/diff wrapped for bzip2, 
# adapted from zdiff by Philippe Troin &lt;phil@fifi.org&gt; 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.
