You will need a configuration file for the user performing the building.
Place it at ~/.config/arch_repo_builder/config.xml - you can find an example one in sample.config.xml

It also requires the following packages to be installed on the buildbox, and the buildbox (not the repo mirror server
itself, necessarily) needs to be Arch:

- devtools
- namcap
- pacman
- rsync
- python-gpgme
- python-lxml
- python-paramiko
- python-requests

It is designed to be run as a *non-root* user. Use the regen_sudoers.py script to create a sudoers
CMND_ALIAS (https://www.sudo.ws/man/1.7.10/sudoers.man.html) to add for your packaging user.
