You mean it's run at the same time as "make"?

was?

Should this instead be in a snippet in the origin record?

Would it make sense to have it in #:make-flags?

>+from natural semantics through structural operational, axiomatic, and
>+denotational semantics, for a miniature example of an imperative programming
>+language.  Their encoding, the proofs of equivalence of different styles,
>+abstract interpretation, and the proof of soundess obtained from axiomatic
>+semantics or abstract interpretation is done in Coq.  The tools can be run
>+inside Coq, thus making them available for proof by reflection.  Code can also
>+be extracted and connected to a yacc-based parser, thanks to the use of a
>+functor parameterized by a module type of strings.  A hand-written parser is
>+also provided in Coq, without associated proofs.")
