For installation, some knowledge about haskell toolchain
(cabal-install for example) is quite needed although it is not crazily
difficult once getting used to it. For you to just start, you need to
have ghc-7.4 or higher and cabal-install installed on your system, and
clone the following packages from http://github.com/hep-platform :
HEPUtil
conduit-util
LHEParser
LHE-sanitizer
madgraph-auto
madgraph-auto-model
pipeline-eventgen
evchain
and at each directory, you need to run cabal install
After evchain is installed, you need to write a script in haskell for
using evchain.
One actual example of such script is
