| # 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. | |
