\string\mathchardef's prepared, 11 math families preloaded.}
\let\mathpreloaded=K
% Math modifiers:
% \lightmath .... Light version of math
% \widermath .... More amount of spaces between characters
% \bfnmath ...... Normal \bf in math (by default is sans bf)
% \sansmath ..... Sans serif math
% \uprightmath .. Capital letters are upright
% \bbcharss ..... Blackboard characters sans serif
% \greekup ...... Lowercase greek upright
% \partialup .... Upright partial derivations symbol
% \narowiints ... Multiplied integrals narrower
% \kpmathreset .. Returns to the default setting
% Basic math selectors:
% \normalmath ... Normal version
% \boldmath ..... Bold version
% Usage: [math-modifiers]\basic-math-selector
% See the file kp-fonts.tex for text modifiers documentation.
