CommitLineData
b1c2e580 1/////////////////////////////////////////////////////////////////////////////
2// Generator using UHKM 3.0 as an external generator. //
3// ( only the HYDJET++ part is implemented for a moment) //
4// temporary link: //
5// http://lav01.sinp.msu.ru/~igor/hydjet++/hydjet++.txt //
6// The main UHKM options are accessable through this interface. //
7// Uses the TUHKMgen implementation of TGenerator. //
8// Author of the first implementation: Sergey Zaporozhets //
9// (zaporozh@sunhe.jinr.ru) //
10// Futhers modifications were made by //
11// Ionut Cristian Arsene (i.c.arsene@fys.uio.no) //
12// & Malinina Liudmila(malinina@lav01.sinp.msu.ru) using as an example //
13// AliGenTherminator.cxx created by Adam Kisiel //
