"None" license

[Arno Hautala]

I'm putting together a Portfile for "symlinks" by Mark Lord. The
source doesn't come with a license and the author has stated that it
doesn't have one [1]. Is there such an identifier for the license
field in a Portfile?

For that matter, is there documentation on valid identifiers?
