+// Macro to make a tag file for a full run directly from ESDs and the GRP
+// Takes as parameters a text file with the location of all ESD files
+// for a given run (can be modified to work on any chain of ESDs)
+// Second argument is the run number, for which the GRP will be retrieved
+// Suitable for a GRID job - runs with pure ROOT to minimize memory 
+// consumption but needs ALIROOT package location to load only necessary
+// AliRoot libraries.
