Stores the appupdater repository files. Also runs a script to generate signatures:
Generate a key for each new release.
make key
Take note of the public id - this is the number after the slash when doing:
make list_keys
http://www.gnupg.org/gph/en/manual/x135.html
Note that we're using detached signatures (.asc) not regular signatures (.sig)
make signatures
After all this - it doesn't work. Problems with verifying the detached signatures on the appupdater side.
