3 loadlibs.C    //modified version of the one used for GEMtest code. I haven't looked into this so it probably contains a lot of stuff that is not needed
4
5 AliToyMCTrack, AliToyMCEvent //classes for storing event and track parameters
6
7 AliToyMCEventGenerator   //base class for event generators, contains DistortTrack method to distort track using method borrowed from AliTPCCorrection
8
9 AliToyMCEventGeneratorSimple  //simple first MC event generator, borrowing from Marians macro. Inherits from AliToyMCEventGenerator to get DistortTrack method. Generate(Double_t time) generates and returns an event at time time
10
11 makeTree.C  //short macro to generate events from a poisson distr and storing in a ROOT tree.
