+/**
+ * @file makeGlobalHistoConfigObject.C
+ * @brief Creation of Global Histo component configuration objects in OCDB
+ *
+ * <pre>
+ * Usage:
+ *  aliroot -b -q makeGlobalHistoConfigObject.C'("path", "key", "uri", runmin, runmax)'
+ * </pre>
+ *
+ * Create an OCDB entry with a TObjString containing param.
+ * Many HLT components understand configuration strings containing
+ * arguments and parameters just like the command line arguments.
+ * This macro facilitates the creation of an appropriate object
+ * from a parameter string.
+ * As another approach the TObjString parameters are stored in a TMap
+ * associated to a key. A TMap object is generated if 'key' is specified.
+ *
+ * Parameters: <br>
+ * - path           path of the entry within the OCDB (e.g. HLT/ConfigHLT/GlobalHisto)
+ * - uri   (opt)    the OCDB URI, default $ALICE_ROOT/OCDB   
+ * - runmin (opt)   default 0
+ * - runmax (opt)   default 999999999
+ * The parameters of the component configuration should be defined inside function makeString().
+ *
+ * Note: The configuration procedure of an HLT component is not
+ * restricted to that scheme. The implementation is up to the
+ * developer and more complex objects are possible.
