/bin/cat is the minimal starting point. Are you looking for the content
filter to do something specific?

        - It may need a MIME parser.

        - It may need to parse RFC822 addresses in headers

        - It may need a policy database

        - It may need archive decoding modules

        - It may a virus signature database

        - ...

Find the most similar open source filter and start there.

If my response solves your problem, the best way to thank me is to not

"It worked, thanks" in the "Subject" so I can delete these quickly.
