I’ll send you the attachments off the list (as the list handler strips off attachments):
pdftops						Perl script (needed at least Perl 5.8.3)
			to be put into /usr/lib/cups/filter
pdftops.conf					configuration file, needed for the xpdf utility from footballs.com
			to be put into /etc/cups (the Perl scripts reads it from there)

The configuration file can be empty if you use the pdftops utility from poppler-utils.
