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/
We're currently using version 0.34 as downloaded from
http://pdftohtml.sourceforge.net. The only alterations made to the source
package were to remove some "CVS" directories and tidy up the makefiles
slightly (to use ./configure as with the rest of Greenstone).
Also, the #pragma statements were removed to work around a compiler bug
on Mac OS X.
