Include files for code fragments?

[Jeff Bailey]

I'm work on a small programming guide, and I want to make sure that every 
example I include will compile and run correctly.  My idea is to:

@address@hidden main.cpp}

That way I know that there's never any copying errors on the examples.

I can't seem to get it to work, however.  Any suggestions?
