    55Sherpa is a multi-purpose event generator that can be used to generate events in various physics models both at the parton and hadron level. The program can account for parton showering and hadronisation, and, where appropriate, also underlying events.

    7 The Sherpa Monte Carlo is publicly available and can be obtained from [http://www.sherpa-mc.de/ www.sherpa-mc.de/]. The interface to !FeynRules will be available from version Sherpa-1.1.0 on. If you experience any problems with the !FeynRules--Sherpa interface send an email to Claude.Duhr@uclouvain.be and sschuman@staffmail.ed.ac.uk

    10 The !FeynRules interface to Sherpa enables the user to implement his new physics model into Sherpa just by knowing the lagrangian and the !FeynRules model file. The interface is called via 
    11 {{{WriteSHOutput[L1, L2, L3,...] }}} 
    12  
    13 where L1, L2, L3, ... denote the lagrangians which should be used to calculate Feynman rules from.<br /><br />Running the interface creates in the current working directory a new subdirectory !ModelNameSH, where !ModelName is the name of the the !FeynRules model file. This directory contains all the files needed for the implementation of the new model into Sherpa. These files follow a convention agreed on between the !FeynRules and Sherpa authors to provide maximal possible generality and flexibility by being compliant with the Sherpa standards.
