+// DESCRIPTION:
+//
+// Contains helper functions to handle oscar user capabilities. Scanning and
+// adding capabilities are assumed to be more timecritical than looking up
+// capabilites. During the login sequence there could possibly be many hundred
+// scans but only a few lookups. So when you add or change something in this
+// code you must have this in mind, dont do anything that will slow down the
+// adding process too much.
