Macros to do fast simulation of processes important for tuning of reconstruction.

+#############################################################################################
-Currently fast simulation of ionization digitization and cluster
-finder - AliTPCclusterFast
-And the edge effect in rphi testEdgeFit.C
+How to use it?
+a) which macro to use (I know it was somewhere in AliRoot but with the GIT page I dont find it anymore),
+b) what is the basic functionality of the functions
+c) what do I need to run it (aliroot version?)
+d) how would I run it and extract space point resolution and dEdx resolution
+ (best step by step for dummies)?
+
+a) Which macro to use (I know it was somewhere in AliRoot
+
+ Example case - submit 40 jobs with 100 tracks.
+
+ source $ALICE_ROOT/TPCdev/TPC/fastSimul/simul.sh
+ makeEnvLocal #this is just example please setup your environmnet script to set env variables
+ makeSubmitRUN 40 100
+
+c) what do I need to run it (aliroot version?)
+ Recent AliRoot
+
+
+b) What is the basic functionality of the functions?
+ Provides cluster and track functionitility - possible to modify parameters of the reconstruction/ resp. harware setup See example usage simul.C:DrawdEdxResolExample()
