"""make Mozilla contributors more productive

This extension adds Mozilla-centric commands and functionality to Mercurial
to enable contributors to Firefox and related applications to be more

Included are commands that interface with Mozilla's automation infrastructure.
These allow developers to quickly check the status of repositories and builds
without having to leave the comfort of the terminal.
