Not surprising! I couldn't find any inteligible text strings in
the file. The very short prologue in the file defines procedures
for drawing commands and image handling, but no text string handling.
The pages themselves are made up of calls to the drawing procedures,
and ASCII85 encoded images. Is there an option on the pdf2ps command
to get text as text, rather than graphics, in the PostScript output?
If not, then I think we can quickly rule out ghostscript's pdf2ps as a
potential pdf_parser.
