<p>
   This script converts a word file (most versions supported) into a
pure ASCII, a PDF or a PostScript version. Currently, only PostScript
and PDF carry images, and those images might be distorted or such. It's
based on the nice program antiword. see <a
href=http://antiword.cjb.net>antiword.cjb.net</a> for more information
about antiword. Currently, max file size is 3MiB for the upload. This
should be enough!
</p><p>Currently, I tend to end up with the ascii version being 1/100th
of the word document, and the pdf/ps versions being 1/10th of the size.
So if you're gonna send me a word document, rethink that. I'll not read
it. I'll read ascii, and probably pdf/ps too.</p>
