   4 Subject: [PATCH] libweston/weston-log: Add an iterator for going over scope
   5  list
   6
   7 libweston users, with the weston-debug protocol doesn't have a way
   8 to list the debug scopes. This adds an iterator function to browse
   9 over the opaque weston_log_scope.
  10
  11 This also adds two helper functions to get the scope name and its
  12 description.
