6  (JF 04/01/05) The <a href="" target="_top">COIN-OR</a> Branch and Cut code
7  is designed to be a high quality mixed integer code provided under the terms of the
8  <a href="" target="_top">Common Public License</a>.
9  CBC is written in C++, and is primarily intended to be used as a callable
10  library (though a rudimentary stand-alone executable exists).
11  The first documented release was .90.0  The current release is version .90.0.

52  (JF 04/01/05) People from all around the world  are already helping.  There are
53  probably ten people who are do not always post to discussions but are constantly
54  "improving" the code by demanding performance or bug fixes or enhancements.  And there
55  are others posting questions to discussion groups.
