---+FPMC interface for Athena
---++How to compile FPMC and interface
   * Fpmc currnetly works only with relaese 14.2.20 (in rel. 14.2.10., 14.2.22 etc. are some compilation problems, will be solved in near future)
   * Log to Lxplus
   * Go to working directory
   * Create directory <code>testarea/14.2.20</code> (<code>mkdir -p testarea/14.2.20</code>)
   * <code>cd testarea/14.2.20</code>
   * Copy source files for Fpmc: <code>cp -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/External .</code>
   * Copy source files for Fpmc interface: <code>cp -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/Generators .</code>
   * Copy configuration files for developer setting: <code>cp  -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/cmthome2 .</code>
   * Edit <code>requierments</code> file: change line <code>macro ATLAS_TEST_AREA ${HOME}/rp220/testarea14</code> to point to right working directory, e.g. <code>macro ATLAS_TEST_AREA ${HOME}/testarea</code>
   * Run initila setup: <code>source /afs/cern.ch/sw/contrib/CMT/v1r20p20080222/mgr/setup.sh</code>
   * Create setup scripts: <code>cd cmthome2; cmt config; cd ..</code>
   * Setup enviroment: <code>source cmthome2/setup.sh -tag=14.2.20,32</code>
   * Compile Fpmc: 
   <pre>
    cd External/Fpmc/cmt
    cmt config
    source setup.sh
    gmake
    </pre>
   * Compile Fpmc interface:
    <pre>
    cd ../../../Generators/Fpmc_i/cmt
    cmt config
    source setup.sh
    gmake
    </pre>
   * Now <code>cmthome2</code> can be removed: <code>cd ../../..; rm -rf cmthome2</code>
   * Create directory for user setup and copy requirement file: <code>mkdir cmthome; cd cmthome; cp  /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/cmthome/requirements .</code>
   * Edit <code>requierments</code> file: change line <code>macro ATLAS_TEST_AREA ${HOME}/rp220/testarea14</code> to point to right working directory, e.g. <code>macro ATLAS_TEST_AREA ${HOME}/testarea</code>
   * Create setup scripts: <code>cmt config</code>
   * Set up user enviroment: <code>source setup.sh -tag=14.2.20</code>
   * Check out Physics analysis package: <code>cd ..; cmt co !PhysicsAnalysis/AnalysisCommon/UserAnalysis</code>
   * Done, now for common usage see section bellow

---++How to run FPMC
   * Log to Lxplus
   * Go to <code>testarea/14.2.20</code>
   * Set up user enviroment: <code>source cmthome/setup.sh -tag=14.2.20</code>
   * Go to Physic analysis package into run directory: <code>cd !PhysicsAnalysis/AnalysisCommon/UserAnalysis/run</code>
   * Create python job options scritp e.g. <code>jobOptions.fpmc.py</code>, which should looks like:
   <pre>
