Thank you for your willingness to help make NumPy the best array system
available.
 
We have a few simple rules: 
 
   * try hard to keep the SVN repository in a buildable state and to not
     indiscriminately muck with what others have contributed.
 
   * Simple changes (including bug fixes) and obvious improvements are 
     always welcome.  Changes that fundamentally change behavior need 
     discussion on numpy-discussions@scipy.org before anything is 
     done.
 
   * Please add meaningful comments when you check changes in.  These
     comments form the basis of the change-log.  
 
   * Add unit tests to excercise new code, and regression tests
     whenever you fix a bug.
