cl-wkb implements the OGC Well-Known Binary geographic geometry data model, and provides WKB encoding and decoding functionality.

Three people have asked for it—two in one day—so today I've released it under a BSD-like license.

Of probably more use to Lisp GIS hackers (together with cl-wkb, or overall), I'm throwing in: cl-geo, a set of geographic data structures and operations.

I hope some people find it to be useful.
