31 // some fake data has to be created.
32 //
33 // The "fake" input data can be taken using either (a) or (b):
34 // (a) data from a file: Use ReadDCSAliasMap()
35 // the format of the file is explained in ReadDCSAliasMap()
36 // To use it uncomment the following line:
37 //
38 //TMap* dcsAliasMap = ReadDCSAliasMap();
39 //
40 // (b) generated in this macro: Use CreateDCSAliasMap() and its documentation

50 // The shuttle can also process files that originate from DCS, DAQ and HLT.

52 // the online machinery would be there.

54 // calibration programs in DCS, DAQ or HLT. These files can then be retrieved using the Shuttle.
55 //
56 // Files are added with the function AliTestShuttle::AddInputFile. The syntax is:
