:mod:`repoze.bfg` provides a default implementation of a
forbidden view; it can be overridden. See
:ref:`changing_the_forbidden_view`.
+ Thread Local
+ A thread-local variable is one which is essentially a global
+ variable in terms of how it is accessed and treated, however,
+ each `thread
+ <http://en.wikipedia.org/wiki/Thread_(computer_science)>` used by
+ the application may have a different value for this same "global"
+ variable. :mod:`repoze.bfg` uses a small number of thread local
+ variables, as described in :ref:`threadlocals_chapter`. See also
+ the `threading.local documentation
+ <http://docs.python.org/library/threading.html#threading.local>`
+ for more information.
