+"""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]
