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 // | |
