The notice "The license for this application is the Common Development and Distribution License (CDDL), and not the GPL as shown elsewhere. Apparently Google Code does not allow CDDL, so as a concession, you can use this code under GPL v2, if you so choose." appeared at http://code.google.com/p/graphmaker/ at the time of download.  I (Jason Wolfe) have made some changes to these files, which are also placed under the CDDL.
