[Groff] Better OCR for UTP Transcription Project

[Stewart Russell]

[or, oh no, Stewart's banging on aboot djvu again]

I've just noticed that djvuzone.org's Any2DjVu server does OCR. It 
returns a djvu file with an embedded text chunk that can be accessed 
using djvutext.

It's pretty accurate -- looks similar to current OmniPage accuracy, 
which is better than gocr and (I assume) Clara. Our Cultural Imperialism 
Control Department requires me to note that it's English only, for the 
moment.

Kudos again to Ralph for finding this.
