Hi Peter,
Yes, but why don't researchers just publish their TEX file? You can
regard that as the "source code" for generating PDF/PS whatever no?
Building a .tex file can be rather hard with packages and what-not,
plus quite a few of us use lhst2tex as a preprocessor. It's not
impossible, but its not trivial either, and I can't imagine that
anyone would use a .tex over a PDF.
If there is a much better format than PDF as generated by the standard
class files, it should be the authors creating it, not other people
post-processing the tex.
Thanks
Neil
