CompHEP -------------The newest and next to newest versions of CompHEP are now installed under /mn/kvant/hep/ CompHEP. To start the newest version (which Kyrre compiled on his machine), do cd /mn/kvant/hep/CompHEP/comphep-4.5.1 make setup WDIR=$HOME/CompHEPWorkDir for example, to make a working directory CompHEPWorkDir under your home directory. Then you can cd to this directory and do ./comphep if you are not using a UiO PC, you can just copy the archive comphep-4.5.1.tgz and compile it locally. I used: ./configure --with-gcc4 --with-m64 make all ("--with-m64" is for 64-bit)
