DESCRIPTION="A high-speed compression/decompression library by Google"
HOMEPAGE="https://github.com/google/snappy"
SRC_URI="https://github.com/google/${PN}/archive/${PV}.tar.gz -> ${P}.tar.gz"
LICENSE="BSD"
SLOT="0/${PV%%.*}"
KEYWORDS="~alpha amd64 arm arm64 ~hppa ~ia64 ~mips ppc ppc64 ~s390 ~sparc x86 ~amd64-linux ~x86-linux ~x64-macos"
IUSE="test"
RESTRICT="!test? ( test )"
# all test dependencies are optional:
# - gflags-2.2 is supposedly needed for command-line option parsing
# but it's a huge hack and does not work,
# - gtest probably gives nicer output,
# - compression libraries are used for benchmarks which we do not run.
DEPEND="test? ( dev-cpp/gtest )"
# AUTHORS is useless, ChangeLog is stale
