+"""ExtensionClass
+
+Extension Class exists to support types derived from the old ExtensionType
+meta-class that preceeded Python 2.2 and new-style classes.
+
+As a meta-class, ExtensionClass provides the following features:
+
+- Support for a class initialiser:
+
+  >>> from ExtensionClass import ExtensionClass, Base
+
+  >>> class C(Base):
+  ...   def __class_init__(self):
+  ...      print 'class init called'
+  ...      print self.__name__
+  ...   def bar(self):
+  ...      return 'bar called'
+  class init called
+  C
+  >>> c = C()
+  >>> int(c.__class__ is C)
+  1
+  >>> int(c.__class__ is type(c))
+  1
+
+- Making sure that every instance of the meta-class has Base as a base class:
+
+  >>> class X:
+  ...     __metaclass__ = ExtensionClass
+
+  >>> Base in X.__mro__
+  1
+
+- Provide an inheritedAttribute method for looking up attributes in
+  base classes:
+
+  >>> class C2(C):
+  ...   def bar(*a):
+  ...      return C2.inheritedAttribute('bar')(*a), 42
+  class init called
+  C2
+  >>> o = C2()
+  >>> o.bar()
+  ('bar called', 42)
+
+  This is for compatability with old code. New code should use super
+  instead.   
+
+The base class, Base, exists mainly to support the __of__ protocol.
+The __of__ protocol is similar to __get__ except that __of__ is called
+when an implementor is retrieved from an instance as well as from a
+class:
+
+>>> class O(Base):
+...   def __of__(*a):
+...      return a
+ 
+>>> o1 = O()
+>>> o2 = O()
+>>> C.o1 = o1
+>>> c.o2 = o2
+>>> c.o1 == (o1, c)
+1
+>>> C.o1 == o1
+1
+>>> int(c.o2 == (o2, c))
+1
+
+We accomplish this by making a class that implements __of__ a
+descriptor and treating all descriptor ExtensionClasses this way. That
+is, if an extension class is a descriptor, it's __get__ method will be
+called even when it is retrieved from an instance.
+
+>>> class O(Base):
+...   def __get__(*a):
+...      return a
+... 
+>>> o1 = O()
+>>> o2 = O()
+>>> C.o1 = o1
+>>> c.o2 = o2
+>>> int(c.o1 == (o1, c, type(c)))
+1
+>>> int(C.o1 == (o1, None, type(c)))
+1
+>>> int(c.o2 == (o2, c, type(c)))
+1

+"""Records
+
+Records are used to provide compact storage for database query result rows.
+
+They don't use instance dictionaries. Rather, they store they data in
+a compact array internally. They use a record schema to map names to
+positions within the array.
+
+>>> class R(Record):
+...     __record_schema__ = {'a': 0, 'b': 1, 'c': 2}
+
+>>> r = R()
+>>> r.__dict__
+Traceback (most recent call last):
+...
+AttributeError: __dict__
+
+>>> r.a
+>>> r.a = 1
+>>> r.a
+1
+>>> r.b
+>>> r.c
+
+Records can be used as mapping objects:
+
+>>> "%(a)s %(b)s %(c)s" % r
+'1 None None'
+
+>>> r['a']
+1
+
+>>> r['b'] = 42
+
+And like sequences:
+
+>>> r[0]
+1
+>>> r[1]
+42
+>>> list(r)
+[1, 42, None]
