It is mostly an Emacs Lisp package but uses as a subprocess, an X Windows
program that graphically displays trees output by the textual OO-Browser.
I have an existing Makefile for this program, called xoobr, and have
started applying the various auto-configuration tools to it but need help
finishing it off. It should be very simple for anyone experienced with
autoconf and I will send the complete source code to you to work on.
