%description
This project provides backends, filters, and other software that was once
part of the core CUPS distribution but is no longer maintained by Apple
Inc. In addition it contains additional filters and software developed
independently of Apple, especially filters for the PDF-centric printing
workflow introduced by OpenPrinting and a daemon to browse Bonjour broadcasts
of remote CUPS printers to make these printers available locally and to
provide backward compatibility to the old CUPS broadcasting and browsing
of CUPS 1.5.x and older.
