(written in C). The Word document must first be saved to disk in RTF format. I'd like to hear of experiences with these. (They only handle RTF versions up to WinWord 2, not yet WinWord 6; there are great differences between these rtf versions and I definitely have problems with WinWord6-rtf with any rtf-converter.)

First, Paul Dubois <dubois@primate.wisc.edu> wrote an RTF reader and converter to plain text or troff. The version is dated April 1991.

a) Based on this reader, Robert Lupton <rhl@astro.princeton.edu> wrote the rtf2TeX converter. Last revision date: May 1992

He comments on this as follows (README-file):

 This is a first attempt at an RTF to TeX converter. The parts that handle
 fonts and such like seem to work pretty well, although they could be
 improved, but the table handling is a problem. I had a good deal of trouble
 trying to figure out what particular rtf control codes were supposed to do;
 this makes it hard to convert them into TeX. I have tried to produce good
 TeX, but this is not easy due to the sloppy way that many RTF writers
 generate redundant font and other changes.  Many things are not handled at
 all, more due to my lacking motivation than to their intrinsic
 difficulty. For example, I don't support double columns, but it would be
 easy enough to do (I'd generate a control sequence to do it, and add the TeX
 code required to the TeX_defs file. I even have the TeX somewhere...).

So far the beginning of the README file. Later he commented:

citation begin>>
 Most (all?) RTF is hopelessly unstructured
 (the equivalent of \bf \it Hello \rm World \bf He \it \rm said. )

and the code that I wrote tries valiantly to convert this to something
sensible, in this case {\it Hello\/} World {\bf He} said.

 It is this attempt to make the output TeX usable that makes the code
 complicated...  I did not try to convert equations or tables as I could find
 no adaquate description of either; I don't think that it would be very hard.

My comment is: Tables yes, but formulas will be difficult. Can be found on all CTAN sites, dir …/support/rtf2tex

b) Based on these two, Erwin Wechtl wrote the rtf2LaTeX converter. Last revision date: Aug. 1993

He comments on this as follows (README-file):

citation begin>>
 rtf2LaTeX is a filter built on Paul DuBois' RTF reader that converts RTF
 (Microsoft's Rich Text Format) into LaTeX. rtf2LaTeX expends a good deal of
 effort in an attempt to make the resulting LaTeX maintainable and
 modifiable.
