General Purpose PostScript Generating Utility
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
(see section 7.3.2 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.
