Short description

A set of LaTeX macros to have symbols designed for Graph Theory. Symbols are available for (directed and undirected) adjacency and incidency, for logical operations on one relation, or many relations (of same arity), instead of boolean values (meta-not, meta-or, meta-and), etc. All symbol macros come in two "flavors": a normal one that works in both text mode and math mode, without any spacing control; a "Relation" one that works only in math mode, with automatic spacing of mathematical relations.

Installation

1. Run "make" to build all the files.
2. Run "make clean" to remove the unnecessary files.

Support

This package is gratis and free. But if you can star it on GitHub, it is a nice encouragement.
