10 | // copy some alice objects from 1 file to another | |
11 | // | |
12 | // ToDo: | |
13 | // add support for more events in 1 file | |
14 | // | |
15 | // | |
16 | // Note: | |
17 | // copied objects are not deleted, I assume that the root | |
18 | // session is exited after this copy | |
19 | // | |
20 | // Example: | |
21 | // aliroot -b -q CopyAli.C\("galice.root","TreeK.root",0,1,1,1\) | |
22 | // | |
23 | // History: | |
24 | // | |
25 | // 21.3.02 - first version | |
