I no longer develop !PDF. Development of !PDF is however continued by Colin Granville. You can find the latest version of !PDF at this site.
If you want to view my old !PDF page you can go here.
I would like to thank Derek Noonberg for developing xpdf in the first place and Colin Granville for continuing development of !PDF now that I am busy with other things.
I would also like to thank all who have contributed to the development of !PDF by reporting bugs, giving advice and telling me to keep on going.
