diffcoeff: a package to ease the writing of a variety of differential coefficients Andrew Parsloe (ajparsloe@gmail.com) This work may be distributed and/or modified under the conditions of the LaTeX Project Public License, either version 1.3c of this license or (at your option) any later version. The latest version of this license is in http://www.latex-project.org/lppl.txt %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Version 5.0 of diffcoeff introduces many interface incompat- ibilities with version 4. For that reason v5.0 and v4.2 are are packaged together. Version 4 can always be used to comp- ile an older document by using the trailing optional argument in the \usepackage statement, e.g., \usepackage{diffcoeff}[=v4] The aim in both versions is to ease the writing of differential coefficients (derivatives) and related quantities (jacobians, differentials). Both versions require xtemplate from the l3packages bundle. Version 5 also requires the mleftright package.
