-# Polymorphic class system built on top of core Jam facilities.
-#
-# Classes are defined by 'class' keywords::
-#
-#     class myclass
-#     {
-#         rule __init__ ( arg1 )     # constructor
-#         {
-#             self.attribute = $(arg1) ;
-#         }
-#
-#         rule method1 ( )           # method
-#         {
-#             return [ method2 ] ;
-#         }
-#
-#         rule method2 ( )           # method
-#         {
-#             return $(self.attribute) ;
-#         }
-#     }
-#
-# The __init__ rule is the constructor, and sets member variables.
-#
-# New instances are created by invoking [ new <class> <args...> ]:
-#
-#     local x = [ new myclass foo ] ;        # x is a new myclass object
-#     assert.result foo : [ $(x).method1 ] ; # $(x).method1 returns "foo"
-#
-# Derived class are created by mentioning base classes in the declaration::
-#
-#     class derived : myclass
-#     {
-#          rule __init__ ( arg )
-#          {
-#              myclass.__init__ $(arg) ;  # call base __init__
-#
-#          }
-#
-#          rule method2 ( )           # method override
-#          {
-#              return $(self.attribute)XXX ;
-#          }
-#     }
-#
-# All methods operate virtually, replacing behavior in the base classes. For
-# example::
-#
-#     local y = [ new derived foo ] ;            # y is a new derived object
-#     assert.result fooXXX : [ $(y).method1 ] ;  # $(y).method1 returns "foo"
-#
-# Each class instance is its own core Jam module. All instance attributes and
-# methods are accessible without additional qualification from within the class
-# instance. All rules imported in class declaration, or visible in base classses
-# are also visible. Base methods are available in qualified form:
-# base-name.method-name. By convention, attribute names are prefixed with
-# "self.".
