3// This class runs the test preprocessor
4// It uses AliTestShuttle to simulate a full Shuttle process

6// The input data is created in the functions
7// CreateDCSAliasMap() creates input that would in the same way come from DCS
8// ReadDCSAliasMap() reads from a file
9// CreateInputFilesMap() creates a list of local files, that can be accessed by the shuttle

36 // To use it uncomment the following line:

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.

56 // Files are added with the function AliTestShuttle::AddInputFile. The syntax is:
