game-data-packager will read GOG.com archives
or windows Steam installations and will create .rpm's
for local use that install needed game assets in
/usr/share/rott

it's easy to add optional support for G-D-P
in a non-intrusive way; if this tool it not used,
the ROTT launcher will default to the previous
behaviour (autodownloader or zenity prompt).
