% Based on Young Ryu's txfonts.sty, v.3.2.1
% Changes to original txfonts.sty:
% Change by Thomas Esser, June 2002:
% Replaced hex numbers by octal to avoid trouble with active "
% as in german.sty.
% Approved for release by Young Ryu (the author) in January 2005.
%
% Changes from original txfonts.sty by Michael Sharpe, msharpe at ucsd dot edu;
% Text and math versions now separate.
% Math version doesn't require newtxtext.sty;
% Added scaled keyword and osf option;
% Modified the definition of \k to bypass problem with grouping;
