Gopher requires GNO (2.0.4, perhaps 2.0.6) and Marinetti (3.0b3).

Usage:

gopher [-o filename] [-O] gopher-url

-o filename: save as filename
-O: save as the remote filename

gopher urls look like:

gopher://server:port/path

where :port is optional.  The first character of path is actually
the type code (5 and 9 are binary, others are text).

A blank path is assumed to be a directory listing but could be anything.
