Feynman diagrams are the standard method for communicating complicated high-energy physics calculations.

FeynDiagram is a library of C++ routines that allows you to draw high-quality PostScript Feynman diagrams by writing a short C++ program to describe the diagram (ie. where the vertices and lines go). Knowledge of C++ is not necessary, but a C++ compiler is.

FeynDiagram may be freely downloaded and distributed.
