How to include cweb-generated plain tex files in latex (OT?)

[Peter.Robinson@t-online.de]

Dear list,
please forgive this somewhat OT question, but a hour's worth of googling didnt turn up a solution. I have done a recent programming project 
with Knuths literate programming cweb package, which is an amazing tool that generates C code and documentation automagically.
Now I would like to include the generated plain tex files in a LaTeX document, but this seems to generate 100s of
errors. Is there something I am missing?

THanks

Peter
