Usage: $(basename $0) [--debug] <branch>
This script takes the intended branch, "testing" or "stable", as the single
parameter. It then tries to autodetermine the correct release name, builds
gluon for the corresponding branch and all supported platforms (excluding
x86*), and optionally signs it if an ecdsutils keyfile is found (standard path:
~/.ecdsakey)
