htmldoc instead of html2ps?

[vicka rael corey <vicka@xxxxxxxxxxxxx>]

i have a system on which i can't use html2ps because of its
large number of dependencies.  instead, i'm using another
html-to-postscript converter called htmldoc.  this works 
very nicely for creating postscript; i run 

"htmldoc -t ps [--webpage] <filename.html> > <filename.ps>", 

and printing that .ps file through lpr and apsfilter looks great.

my question is, what do i need to change in apsfilter so that
it does this with html files automagically, rather than trying
to invoke html2ps?

thanks,
