For the eqnarray* environment:
<assign|eqnarray*|<macro|body|<with|paragraph mode|center|mode|math|formula
style|true|interline space|0.45fn|<surround|<format|no page break
before><vspace*|0.5fn>|<vspace|0.5fn><format|no indentation
after>|<tformat|<twith|table hyphen|y>|<twith|table
width|1par>|<twith|table min cols|3>|<twith|table max
cols|3>|<cwith|1|-1|1|1|cell lsep|0spc>|<cwith|1|-1|-1|-1|cell
rsep|0spc>|<cwith|1|-1|1|-1|cell bsep|0sep>|<cwith|1|-1|1|-1|cell
tsep|0sep>|<cwith|1|-1|1|1|cell hpart|1>|<cwith|1|-1|-1|-1|cell
hpart|1>|<cwith|1|-1|1|1|cell halign|r>|<cwith|1|-1|1|1|cell
hyphen|b>|<cwith|1|-1|2|-2|cell halign|c>|<cwith|1|-1|-1|-1|cell
halign|l>|<cwith|1|-1|-1|-1|cell hyphen|t>|<arg|body>>>>>>
in the 'tformat' command I don't understand precisely how the 'cwith' command
works. The 'cell halign|l' command is clear but the '|1|-1|-1|-1|' remains a
mystery.

From my point of view this is a problem for tensor notation: in the
expression A_{ijk} the index ijk should not be typed with a roman font.

I can help for this task but I don't know much about the Scheme language...
A good thing to do in parsetex.cc would be to delete all comments before
actually parsing the LaTeX file.

I worked with 1.0.0.9
