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
