 # This script is intended to be used as a CUPS backend, to create
 # PDF file on-the-fly. Just create a printer using the device uri
 # pdf:/path/to/dir/. When printing to this printer, a PDF file
 # will be generated in the directory specified. The file name will
 # be either "<jobname>.pdf" or "unknown.pdf", depending wether the
 # jobname is empty or not.
 #
 # To use it, simply copy this script to your backend directory, and
 # create a printer with the correct URI. That's it.
