% Based on Young Ryu's txfonts.sty, v.3.2.1
% Text and math are now loaded in separate sty files---the text
% font family need not be txtext. The text font loaded when this package
% is processed is used for operator names, mathrm, mathit, 
% and likewise for mathsf and mathtt.
% The original txfonts math fonts have been replaced by virtual fonts which
% render less tightly so that there are many fewer instances 
% of glyph collisions.
% These modifications are by Michael Sharpe, msharpe at ucsd dot edu
