+This library uses iText 2.1.7, which is the last LGPL/MPL version of the iText project. 
+
+We've used iText for several years. The license for iText has changed for subsequent versions and is no longer compatible with Processing, so we're stuck at 2.x. 
+
+At the iText site, there's also some [vague wording](http://lowagie.com/itext2) about legal liability for commercial projects using the 2.x series. It's not clear where this leaves us.
+
+Bruno Lowagie did an enormous amount of (free) work with the iText project, and we certainly don't fault him for the new commercial license. 
+
+We're using iText in a very limited way--drawing to it like it's a Java Graphics2D object. There might be other options for us in this space, but it's not much of a priority.
