        explanation of the format. Remember to keep these files sorted. The file
        <c>use.local.desc</c> is automatically generated from entries in the
        package's <c>metadata.xml</c> and may be used by tools that parse the tree.
+       Since <c>use.local.desc</c> is automatically generated it must never be
