Comment (by jstolarek):

 `-frule-check` flag is not described at all. Here's an excerpt from
 `Rules.lhs`:

 {{{
    We want to know what sites have rules that could have fired but didn't.
    This pass runs over the tree (without changing it) and reports such.

 \begin{code}
 -- | Report partial matches for rules beginning with the specified
 -- string for the purposes of error reporting
 }}}
