flexfax: HFAXD - catch PS file before convert

[sb <sb@gfad.de>]

 high there,

i'm new in this list - greetings out ...

i have a question about the hylafaxd and the handling with the incoming ps
file that comes in from a hylafax client e.g. whfc. 
how can i modify this file before it would be converted to a fax file?

i would like to use another printerdriver for W95 with special features in font
handlings. this driver makes also a PS file but i would like to catch this file
for converting this into a different format.

can anybody help me?

thx 
sven
