A CVS repository for Panda can now be found at https://savannah.nongnu.org/projects/panda/
I have finally gotten around to making my AUUG 2001 presentation available online. The slides can be found here. The talk covers how to use Panda and PandaLex
PDF 1.4 has now been released in the sense that Adobe Acrobat 5 supports it (as has Illustrator 9 for some time).
The PDF parsing code has been forked into the separate PandaLex project, which should make this code more useful to people who only want to parse PDF documents.
Please note that this is a testing release and might not work as expected. The documentation inside the release is also not always up to date — check main.c for samples of how to use the functions. Please report any problems to me and to the Panda Development mailing list mentioned at the top of this page.
