| 32 | // Description: |
---|
| 33 | // cloned from BabarEvtReadGenerator, it interpets the information in the |
---|
| 34 | // stdhep ascii files produced by GenFwkInt and passes it along to G4 |
---|
| 35 | // (both vertex and 4-vector information). |
---|
| 36 | // |
---|
| 37 | // This class is used in the Bogus standalone application. |
