Comment (by dcoudert):
In the description of method {{{graph_classes.smallgraphs}}} is weird:
{{{
sage: graph_classes.smallgraphs?
Type: CachedMethodCallerNoArgs
String form: Cached version of <function smallgraphs at 0x1132b62a8>
File: /Users/dcoudert/sage/local/lib/python2.7/site-
packages/sage/misc/cachefunc.so
Definition: graph_classes.smallgraphs(self)
Docstring:
Returns a dictionary associating a graph to a graph description
string.
Upon the first call, this loads the database from the local XML
files. Subsequent calls are cached.
EXAMPLES:
sage: t = graph_classes.inclusions()
sage: type(t)
<type 'list'>
sage: t[0]
{'sub': 'gc_1', 'super': 'gc_2'}
Class docstring:
Utility class that is used by "CachedMethod" to bind a cached
method to an instance, in the case of a method that does not accept
any arguments except "self".
Note: The return value "None" would not be cached. So, if you
have a method that does not accept arguments and may return
"None" after a lengthy computation, then "@cached_method" should
not be used.
EXAMPLE:
sage: P.<a,b,c,d> = QQ[]
sage: I = P*[a,b]
sage: I.gens
Cached version of <function gens at 0x...>
sage: type(I.gens)
<type 'sage.misc.cachefunc.CachedMethodCallerNoArgs'>
sage: I.gens is I.gens
True
sage: I.gens() is I.gens()
True

Init docstring:
EXAMPLES:
sage: class Foo:
....: def __init__(self, x):
....: self._x = x
....: @cached_method
....: def f(self):
....: return self._x^2
sage: a = Foo(2)
sage: print a.f.get_cache()
None
sage: a.f()
4
sage: a.f.get_cache()
4
Call docstring:
Call the cached method.
EXAMPLE:
sage: P.<a,b,c,d> = QQ[]
sage: I = P*[a,b]
sage: I.gens() # indirect doctest
[a, b]
sage: I.gens() is I.gens()
True
}}}
Furthermore, the example exposes {{{graph_classes.inclusions()}}} but not
{{{graph_classes.smallgraphs()}}}.
The rest seems ok.
David.
