DESCRIPTION="POSIX 1003.1e capabilities"
HOMEPAGE="https://people.redhat.com/sgrubb/libcap-ng/"
# Patch works around / reverts a behaviour change because not all consumers were ready.
# Keep this patch for a bit longer until Fedora stop shipping it (not clear what else
# other than gnome-keyring was broken by it: bug #759550)
# Fedora 0.8.2 https://src.fedoraproject.org/rpms/libcap-ng/c/a5b0f536df1132d8e7afa4c0ce07b630e7970cad?branch=master
