Usage example:

1) Create an aab.conf file describing your template.

--- Example aab.conf:
Name: base
Version: 2015-08-21-1
Section: optional
Maintainer: Your Name
Headline: ArchLinux base image.
Architecture: x86_64
Source: http://archlinux.cu.be/$repo/os/$arch
--- End of example

2) Run as root:

  # ./aab init
  # ./aab bootstrap

3) Maybe install additional packages

  # ./aab install base-devel

4) Create the archive and clean up:

  # ./aab finalize
  # ./aab cleanup
