DESCRIPTION="A spaceship bridge simulator game"
HOMEPAGE="https://daid.github.io/EmptyEpsilon/"
# This bundles SeriousProton as the build system does not support using
# a separate SeriousProton instance (and currently EmptyEpsilon seems to
# be the only consumer).
SRC_URI="https://github.com/daid/EmptyEpsilon/archive/EE-${PV}.tar.gz -> EmptyEpsilon-${PV}.tar.gz
https://github.com/daid/SeriousProton/archive/EE-${PV}.tar.gz -> SeriousProton-${PV}.tar.gz"
# EmptyEpsilon is mostly licensed under GPL, however the art ressources
# use Creative Commons and the bundled SeriousProton is MIT-licensed.
