cweb - how to use?

[Patrick Gundlach <gundlach@irb.cs.uni-dortmund.de>]

Hi!

I just tried to use the cweb macros but the only thing I get are 
error messages:

gundlach@sarti:~/tmp$ texexec --usemodule cweb wc.tex

the same with the other special cweb macros.

I would like to have a file like CWEB-MAC.PDF
