# A hacky script to generate .pkg.tar.?z files using satellites.
# It's a fairly simple wrapper to astronaut, that generates pacman packages.

# This may also serve as an example on how you can wrap astronaut to package in any format.
# Sure, no dependency resolution, and the packages won't make it in any official repositories,
#   but it isn't meant for that anyway.
