+Subject: [PATCH] libweston/weston-log: Add an iterator for going over scope
+ list
+
+libweston users, with the weston-debug protocol doesn't have a way
+to list the debug scopes. This adds an iterator function to browse
+over the opaque weston_log_scope.
+
+This also adds two helper functions to get the scope name and its
+description.
