Project:Repository mirror and CI

The project is currently running:
 * basic automated QA checks against all repositories (sync, validate metadata),
 * git mirrors of repositories with pregenerated metadata cache.

On todo:
 * automatically file bugs against new QA violations in repositories.

Resources:
 * QA check results
 * repository mirrors
 * XML repository list using mirrors as sources (for layman)
 * scripts used to run the mirror&CI

In order to make layman use the mirrors instead of original repositories, use the following configuration:

Note that the mirror's XML file must come after Gentoo's in order to overrride the mirrored Gentoo repositories.

The scripts are running on hardware provided by Todd Goodman. Result files and mirrors are hosted on GitHub.
