Jordan K. Hubbard 6f52f41fb2 A programmatic interface to ftp. I need this for several other
components of the system.

The license is poorly worded, though I have an (email only) release
from the author for unlimited FreeBSD use.  I will try to get something
more concrete, though the author's remote location makes this difficult.
