Hungry ViewKit

A C++ class library for developing Motif application programs (although this restriction will be lifted once LessTif is finished). It follows the API of the Iris(tm) ViewKit, put out by SGI. The Hungry ViewKit is a superset of the Iris ViewKit, so any code developed for the Iris version will work with the Hungry version, but possibly not vice versa.
