MuPDF ===== The MuPDF is a library and a set of example PDF viewers. It's not full-featured and it cannot replace more complex products for all tasks (there is probably no support for forms nor annotations). But for viewing of PDF files it is excellent because: - it is FAST. It's much faster than the XPdf, actually, - the viewer are controlled from the keyboard, - it can run almost everywhere. I have been using an older version of this nice thing on my Ben NanoNote as it's only PDF viewer. And recently the Nekochan.net user Jimmer recently made an IRIX port of the basic (X11) viewer [2]. The viewer can handle PDF files that are too new both for the last Adobe Reader version available here (4.x) and it's official replacement (a polished XPdf). And it can handle the files several times (!) faster than these old programs. It might be not so important on a modern PC but it's very noticeable on a computer with only 250 MHz processor. The recent MuPDF can even handle EPUB files. It's not perfect (some images are ignored) but it has no problem with Czech language characters and text rendering is very nice. Of course, no one should use a SGI workstation as an e-book reader but it's useful to have a possibility to see these files. So it's a nice feature, too. That's a nice improvement for my workstation!
