Usage: $program FILE1 FILE2 [-- A2PS-OPTIONS...]
Pretty print the differences between FILE1 and FILE2.

Options:
 -h, --help           display this help and exit
 -v, --version        display version information and exit
 -q, --quiet          don't print informational messages
 -l, --lines          search for line differences (\`diff')
 -w, --words          search for word differences (\`wdiff')
 -o, --output=FILE    save the output in FILE

Options for a2ps are given after \`--', for instance
