//
// This is an example steering macro for running RSN analysis task
// with the AliEn plugin on PROOF.
//
// Inputs:
//
//   - runMode     = AliEn plugin run mode
//   - suffix      = eventual suffix which is attached to the automatic name created for outputs
//   - partname    = a string which defines the resonance name (used for output)
//   - runList     = configuration file whith gives list of runs, pattern, prefix, options and AliEn path
//   - split       = corresponding JDL value
//   - nmerge      = number of outputs to be merged per stage
//
//   - taskList    = a string containin all the 'add-task' macros to be used
//   - taskPath    = the uniqu pathe where all 'add-task' macros (and all their needs) are stored
//
//   - workDirBase = path of the working directory (starting from AliEn home)
//   - outDir      = path of the output directory (w.r. to workDir)
//
// Notes:
//
//   - in case the source is an ESD, and if inputs are a MC production
//     the MC input handler is created by default
//
//
// In principle, the user should never modify this macro.
