Note: The iText support module is functional, but incomplete. So feel free to download the sources and extend them. Joining the project is easy and there's a mailing list as well. So, feel free to become part of this project if you find this functionality useful.
If you encounter problems setting everything up (which is a little tricky since you need the iText API JAR to compile the module and also to make the functionality itself work), please join the mailing list and send an e-mail there. It is probably best to keep all queries about this module in the same place.
