I’m fond of saying ‘All you have to do is…’ is one of the biggest lies ever

Good luck! i’ve actually had some limited success using ps2ascii’s more complex
output modes to derive structure from font/size specifications and
spacing/location,
converting a PDF file to some kind of markup. Of course, it’s very specific to
individual documents — it’s actually a collection of scripts, one of which
returns
a list of fonts and sizes used in a document and the number of characters used
for each. i would use that to build a table, specifying whether strings with
that
format were inline or block, and the kind of markup to wrap them in.
Paragraph detection is, um, fun. Some books use indents, others use vertical
space. And don’t get me started on definition lists or tables…
