Changes since 1.6: +36 -15 lines 

license update of CMU parts.  due to communication with wcw+@andrew.cmu.edu,
pushed for by tygs@netcologne.de.  Apparently we also now known how to talk
to the lawyers there, if we were so mad.  Note that a few other copyright
issues in pppd still remain, so this does not close this story.
