"Subclass determination is done in a fairly straightforward way, but includes"
" a wrinkle that implementors of extensions to the class system may want to "
"be aware of.  If :class:`A` and :class:`B` are class objects, :class:`B` is "
"a subclass of :class:`A` if it inherits from :class:`A` either directly or "
"indirectly.  If either is not a class object, a more general mechanism is "
"used to determine the class relationship of the two objects.  When testing "
"if *B* is a subclass of *A*, if *A* is *B*, :c:func:`PyObject_IsSubclass` "
"returns true.  If *A* and *B* are different objects, *B*'s "
":attr:`~class.__bases__` attribute is searched in a depth-first fashion for "
"*A* --- the presence of the :attr:`~class.__bases__` attribute is considered"
" sufficient for this determination."

"Returns ``1`` if the class *derived* is identical to or derived from the "
"class *cls*, otherwise returns ``0``.  In case of an error, returns ``-1``. "

"The result will be ``1`` when at least one of the checks returns ``1``, "
"otherwise it will be ``0``. If either *derived* or *cls* is not an actual "
"class object (or tuple), this function uses the generic algorithm described "

"Derives a file descriptor from a Python object.  If the object is an integer"
" or long integer, its value is returned.  If not, the object's "

"This is equivalent to the Python expression ``dir(o)``, returning a "
"(possibly empty) list of strings appropriate for the object argument, or "
