A small utility to convert RFCs to PDF
Run this:
./rfc2pdf.py rfc4291.txt rfc4291.pdf LiberationMono-Bold.ttf 15 20
The script will take rfc4291.txt and generate a PDF file named rfc4291.pdf where the font used will be LiberationMono-Bold with a lateral margin of 15 and a top and bottom margin of 20. For better results is strongly adviced to use a monospaced font.
Put all your RFCs in a folder (for example RFC-all) and run this:
./bulk_convert RFC-all PDF-Liberation-Mono LiberationMono-Bold.ttf 15 20
