Subject: [svn-r1424] Pulled CVS checkout codes to form a new partition of
 checkout that does cvs checkout only.  Moved the "make distclean" code from
 the "test" to the "release" part.  (A distclean should definitely be applied
 as part of the release command.  Also, test might fail for other silly
 reason, like AFS temporary out.  The distclean blew away the option of trying
 the tests by hand.
