+Integration with the warnings module
+------------------------------------
+
+The :func:`captureWarnings` function can be used to integrate :mod:`logging`
+with the :mod:`warnings` module.
+
+.. function:: captureWarnings(capture)
+
+ This function is used to turn the capture of warnings by logging on and
+ off.
+
+ If `capture` is `True`, warnings issued by the :mod:`warnings` module
+ will be redirected to the logging system. Specifically, a warning will be
+ formatted using :func:`warnings.formatwarning` and the resulting string
+ logged to a logger named "py.warnings" with a severity of `WARNING`.
+
+ If `capture` is `False`, the redirection of warnings to the logging system
+ will stop, and warnings will be redirected to their original destinations
+ (i.e. those in effect before `captureWarnings(True)` was called).
