This one is a modification of a previous recipe which provided a pure Python text to PDF converter.
This version modifies argument parsing using optparse and provides a few additional options to add subject, author, keywords etc. There is also an option to provide arbitrary page breaks using regular expressions. This is useful to convert documents such as RFCs to PDF.
Example...
$text2pdf.py rfc_3917.txt -S "Netflow RFC" -A "Quittek, et al." -K netflow,rfc,networking,ipfix -R "[Page\s+\d+]"
