+% Deprecation stuff.
+% Should be extended to allow an index / list of deprecated stuff.  But
+% there's a lot of stuff that needs to be done to make that automatable.
+%
+% First parameter is the release number that deprecates the feature, the
+% second is the action the should be taken by users of the feature.
+%
+% Example:
+%
+%  \deprecated {1.5.1}
+%    {Use \method{frobnicate()} instead.}
