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 // | |
