// Method 1: Create automatically XML collections using alien 'find' command.
//===========
// Define production directory LFN

//===========
// If no path mentioned data is supposed to be in the work directory (see SetGridWorkingDir())
// XML collections added via this method can be combined with the first method if
// the content is compatible (using or not tags)

// Declare all libraries (other than the default ones for the framework). These will be
// loaded by the generated analysis macro and compiled runtime.
// Add par files, if needed.

// (AddTaskTagCreation.C can be removed from SetAdditionalLibs, if available in the grid aliroot version)

//=====================================================================

//=====================================================================
