This is a fork from Werner Randelshofer's version of JHotdraw.
I use JHotdraw as a generic application framework (not as a drawing app), as Werner Randelshofer has written a sound basis for document-oriented softwares.
You can license JHotDraw 7 either using an LGPL license or using a Creative Commons Attribution (by) 2.5 license.
I use the LGPL here.
