How to install:

Make sure you are using the latest version of PandaRoot!

Download the files from svn to a folder of your choice. (I suggest not to use a folder in $VMCWORKDIR.)

svn co  https://subversion.gsi.de/fairroot/pandaroot/development/mgaluska/eventFilter

Copy 
FairLinkDef.h
CMakeLists.txt
to $VMCWORKDIR/base and replace the existing files.

Copy all other files to 
$VMCWORKDIR/base/sim
and replace existing files.

Recompile PandaRoot.

Take a look at sim_complete.C for example usage of event filters in PandaRoot.

First make sure you did not change your original files and delete them, then you can run:
cp FairLinkDef.h $VMCWORKDIR/base
cp CMakeLists.txt $VMCWORKDIR/base
cp * $VMCWORKDIR/base/sim


Alternatively, you can use the script link.sh to delete the files in PandaRoot and to set hard links. Please read the script before you run it: It deletes the old files automatically!
