Providing a list of input files

[Paul Michael Reilly]

I just used a2ps for the first time.  Very nice tool.  But I wanted to
provide a2ps with a file that contains a list of files to process.
But it does not appear to be something that a2ps can handle.  Before
diving in to add the functionality I thought I'd ask to see if this is
something that is easy and I'm just missing it.

Thanks,
