Software to strip TeX commands?

[Ted Bentley]

Is anyone aware of software to take TeX and LaTeX commands out of a
document so that it could be run through spell(1) without producing
too many extra character strings?  What I am looking for is something
like deroff for stripping troff input.

Please respond by mail about availability.  I will summarize the
results for the net.

Thanks 
Ted Bentley
