Proofreading documents with awk

[Evan Heit]

I am looking for someone who has written a program in awk that will
will allow me to proofread my papers by by looking for word repetitions.

For example, the word "will" is repeated unnecessarily at the beginning of
the second line of this message, and the word "by" is also repeated.  I'm
looking for an awk program to catch word repetitions like these.

Of course, a program in something other than awk (a gnuemacs function?) would
be just as good.  Thanks in advance.
