Iíve been wandering around the different mock pages (wiki/trac), and I havenít found any indications about the preferred way to submit patches for mock. The wiki page tells to go to Trac, and trac doesnít say anything :) So please forgive me for looking at git logs and reaching out to the most recent/active contributor :)

Iíve been working on a small patch  to mock that adds automatic signing of built package. It also introduces a small api change, so please let me know if itís wrong and if you have a better idea :)
Let me also know if thereís a better place to post patches :)
