Abstract
The program MadGraph is presented which automatically generates postscript Feynman diagrams and Fortran code to calculate arbitrary tree level helicity amplitudes by calling HELAS[1] subroutines. The program is written in Fortran and is available in Unix and VMS versions. MadGraph currently includes standard model interactions of QCD and QFD, but is easily modified to include additional models such as supersymmetry.

Standard Latex file. 21 pages. 1 postscript figure appended after "\end{document}". Uses epsf.sty (available from hep-ph) to place figure. Can be TeXed without the figure if you don't have postscript. Harcopies or postscript file of entire paper available on request. MAD/PH/813
