passing options to subfilters?

[Michal Szymanski <msz@xxxxxxxxxxxxxx>]

Hi,

With default configuration, apsfilter uses 'a2ps' utility with options
which force using colors and syntax highlighting for known types of
files, e.g. C program files. 

I know I can change these options in /usr/local/etc/apsfilterrc file
but this would have "global" consequences. That's not necessarily
what I'd want.

Is it possible to dynamically control the subfilter (like a2ps) used by
apsfilter and be able to pass options specific for a2ps in the
"lpr" command line?

And, BTW, could somebody explain how does 'apsfilter' construct options
passed to 'a2ps'? There are at least 2 variables in apsfilterrc:

#A2PS_BASIC="--delegate=no -X iso1 -g"
#A2PS_BASIC='-X iso1'
#A2PS_OPTS='-X iso1 -m --borders=yes --prologue=color --highlight-level=heavy'

It seems as if A2PS_OPTS included A2PS_BASIC, but what will happen if I
uncomment (and change) both?

regards, Michal.
