[Rd] An lgrind definition for the S language

[Douglas Bates]

I seem to recall discussion of an language definition file for S for
use with the lgrind utility but I can't find any trace of it in an R
Site Search.  The lgrind utility takes a file of code in a particular
programming language and prepares it for "pretty printing" in LaTeX. 
In my version the available language definitions are

$ lgrind -s
When specifying a language case is insignificant. You can use the
name of the language, or, where available, one of the synonyms in
parantheses. Thus the following are legal and mark Tcl/Tk, Pascal
and Fortran input, respectively:
   lgrind -ltcl/tk ...
   lgrind -lpaSCAL ...
   lgrind -lf ...

Does anyone know of a similar facility for S code?
