The majority of the work in this library is done by iText.
http://www.lowagie.com/iText/

The version bundled in this release is 2.1.2u. 

The files in the library must be named itext.jar (not iText-2.1.2u.jar) 
because they're specifically included on the classpath as part of the
build/platform/make.sh scripts.
