This is pdftohtml, which was based at:
     http://www.ra.informatik.uni-stuttgart.de/~gosho/pdftohtml/

It has recently been picked up again, and is currently based at:
    http://pdftohtml.sourceforge.net/

The version is based on version 0.22, with some code included from
version 0.31. It has been modified for Greenstone use, particularly
the file xpdf/HtmlOutputDev.cc, in an attempt to get text and images
in roughly the right place without using javascript or multiple pages.

Known problems:
      tables with text.
      multi-column pages.
      some image types don't get extracted.
