This is a simple simulation example showing how to run event simulation using the Hijing event generator interface from AliRoot.
The configuration of AliGenHijing is performed by the function hijing(double energy = 5020., double bMin = 0., double bMax = 20.) defined in the macro aliroot_hijing.macro.
The macro file is specified via --configKeyValues setting GeneratorExternal.fileName whereas the specific function call to retrieven the configuration is specified via GeneratorExternal.funcName.
To run this example you need to load an AliRoot package compatible with the O2. for more details, https://alice.its.cern.ch/jira/browse/AOGM-246
AliRoot needs to be loaded after O2 in the following sense:
alienv enter O2/latest,AliRoot/latest
The other order may show unresolved symbol problems.
