(** Grammar entry for tactics: proof mode(s).
  By default Coq's grammar has an empty entry (non-terminal) for
  tactics.  A plugin can register its non-terminal by providing a name
  and a grammar entry.

  For example the Ltac plugin register the "Classic" grammar
  entry for parsing its tactics.
