Added. Latest version at http://people.freebsd.org/~gordon/man.sh

It's a slightly different heuristic than the existing man implementation
since I don't support the notion of MANPATH_MAP. Here's the order:

Default manpaths (/usr/share/man:/usr/share/openssl/man:/usr/local/man)
Parse $PATH (path/man:path/MAN:(if ending in /bin)path/../man)
Parse config files

Thanks!
