Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
pnmmargin -V (return code: 1)
usage: /usr/bin/pnmmargin [-white|-black|-color <colorspec>] <size> [pnmfile]
pnmmargin --help (return code: 1)
usage: /usr/bin/pnmmargin [-white|-black|-color <colorspec>] <size> [pnmfile]
