Does the new version supersede the previous version?: Yes
Nature of problem:
The program computes the Feynman rules of any quantum field theory, expressed in four-dimensional spacetime, directly from the Lagrangian of the model. Various interfaces to Feynman diagram calculators are included that allow the exportation of the interaction vertices in a format readable by different Monte Carlo event generators or symbolic calculation tools.
FeynRules works in three steps:

Summary of revisions:
Mathematica version 7.0 or higher. The Lagrangian must fulfill basic quantum field theory requirements, such as locality and Lorentz and gauge invariance. Fields with spin 0, 1/2, 1, 3/2 and 2 are supported.
Translation interfaces to various Feynman diagram generators exist. Superfields are also supported and can be expanded in terms of their component fields, which allows the performance of various sets of superspace computations.
The computation of the Feynman rules from a Lagrangian varies with the complexity of the model, and runs from a few seconds to several minutes. See Section 7 of the present manuscript for more information.
