Wydawca is an automatic release submission daemon, i.e. a program designed to handle PGP-signed uploads of software packages and to distribute them to the corresponding target locations, where they become available for download. The program implements the GNU automatic upload procedure, and supports upload directive files of versions 1.1 and 1.2.

Wydawca can be used to process uploads periodically, as a cron job, or in the real time.
