The Linear Equations Preprocessor solves linear equations and then substitutes the solutions into a document at prescribed locations. It provides linear equation solving capability similar to what is provided by MetaPost, as a general purpose preprocessor. It can be used with SVG to specify the position of graphics objects using a set of linear equations. Version 1.1 of lineqpp has been released at its new home on GitHub. https://github.com/ramsdell/lineqpp/downloads A manual is online. http://www.ccs.neu.edu/home/ramsdell/tools/lineqpp.html John
