+===================================================
+ Analysis task for the calculation of the trigger chamber efficiency.
+ Diego STOCCO, Torino
+----------------------------------------------------------------
+
+Purpose: produce histograms for the trigger chamber efficiency determination
+from MUON track info. The task works either with input ESD or AOD (default is ESD).
+
+This version works either locally or on grid.
+
+Files:
+AliAnalysisTaskTrigChEff.cxx -source files of the analysis task
+AliAnalysisTaskTrigChEff.h
+
+AnalysisTrigChEff.C - main macro for analysis
+
+Test analysis:
+- Preliminary: copy the following packages in the current working directory
+ - STEERBase.par
+ - ESD.par
+ - AOD.par
+ - ANALYSIS.par
+ - ANALYSISalice.par
+If the packages are not present, create them:
+cd $ALICE_ROOT
+make STEERBase.par
+make ESD.par
+...
+
+ - Local test:
+ root
+ .x AnalysisTrigChEff.C(kMlocal)
+
+ by default the macro searches for ESD in $ALICE_ROOT/MUON/test_out.100
+ The directory is generated by MUON/AlirootRun_MUONtest.sh (see README in MUON).
+
+ - Grid test (interactive):
+ root
+ .x AnalysisTrigChEff.C(kMlocalGrid)
+
+ by default the macro searches for a wn.xml in the current directory, with the list
+ of grid files to analyse.
