## TODO
# * Add license text
# * Create symlinks from pkgbase to pkgname[@] for easy package finding

## GOALS
# * Have a searchable database of PKGBUILD metadata
# * Have an interface for source-only builds
# * Possibility to hook up ABS dirs besides ABSROOT (low priority)
# * Tell updates and non available binary packages (working on this)
