card [options] applications [-- a2ps-options]
card is a shell script which tries to guess how to get your
applications' help message (typically by the options `--help'
or `-h'), and pretty prints it thanks to a2ps (or the content of
the environment variable `A2PS' if it is set).
a2ps-options are passed to a2ps.
Supported options are:
LC_ALLetc. (such as `fr', `it' etc.).
If the applications don't support internationalization, English will be used.
card --command="cc -flags"
It is possible to give options to a2ps (see section 3.1 Command line options) by specifying them after `--'. For instance
card gmake gtar --command="cc -flags" -- -Pdisplay
builds the reference card of
GNU tar (automatic
detection of `--help' support), and
