But Word2TeX surely won't format the LaTeX output exactly
like it looked in Word.  Therefore, after running Word2TeX,
you will have to do some manual editing of the LaTeX file to
finish formatting the LaTeX version of your paper; this will
require some knowledge of LaTeX.  Word2TeX is available
discounted for about $85; there are also free programs
to help with the Word to TeX conversion.  I suspect that
in all cases you will have to learn something about LaTeX
to finish off the formatting.
