+"""XmlInfo.py is a module for quick introspection of XML Documents.  It will print all the Ids of
+the components defined in an XML document and (if possible) their Doc strings.  Usage:
+    python XmlInfo.py [fileName] [-b] [-i]
+    Example:
+    python XmlInfo.py config/C5Sign.xml
+
+With no flags all components are printed.  With -b, behaviors are printed.  With -i, inputs are
+printed.  (And both if both are specified)
