9.1 'card'
==========

Many users of a2ps have asked for a reference card, presenting a summary
of the options.  In fact, something closely related to the output of
'a2ps --help'.

   The first version of this reference card was a PreScript file (Note:
PreScript) to be printed by a2ps.  Very soon a much better scheme was
found: using a style sheet to pretty print directly the output of 'a2ps
--help'!  A first advantage is then that the reference cards can be
printed in the tongue you choose.

   A second was that this treatment could be applied to any application
supporting a '--help'-like option.
