+        The class allows to guess option names for positional options, which
+        are specified on the command line and are identified by the position.
+        The class uses the information provided by the user to associate a name
+        with every positional option, or tell that no name is known. 
+
+        The primary assumption is that only the relative order of the
+        positional options themselves matters, and that any interleaving
+        ordinary options don't affect interpretation of positional options.
+        
+        The user initializes the class by specifying that first N positional 
+        options should be given the name X1, following M options should be given 
+        the name X2 and so on.
