% Based originally on Young Ryu's pxfonts.sty, v.1.1.1
%
% Changes from original pxfonts.sty by Michael Sharpe, msharpe at ucsd dot edu;
% Text and math versions now separate. 
% Added scaled keyword and osf option;
% Modified the definition of \k to bypass problem with grouping.
% Text is now directed to an extension of TeXGyrePagella rather than ppl.
