Probably I should have explained it before. I agree that the "manpage"
isn't very useful, but I still think it is a lot better than nothing.

Whithout manpage (as the situation is today) the user is left to
himself to figure out where to find documentation. If he is smart
enough, he will look at the port Makefile to see if there is a web
site for the project. If he is not smart enough, he will be without
documentation.

With the manpage, and the USERDOC file (both are installed by this
patch), he can quickly find a pointer to the documentation.
