+Sailfish Access Control
+=======================
+
+This package provides a thin wrapper library on top of the getuid, getpwuid, getgrouplist, and friends.
+Checking whether a user belongs to a group should be done via this Sailfish
+Access Control library.
+
+This will make it easier to fix for instance rerentrancy issues.
