sh and/or csh compilers?

[R. P. C. Rodgers, M.D.]

Dear Netlanders,

I keep hearing rumors of the existence of compilers for various UNIX
shells, but have never come across one (or even an add for one).
Does anyone know of any such beast, or (better yet) have direct
experience with one?  How good are they, and do they significantly
improve execution time?

Thanks and Cheerio, Rick Rodgers
