Log Message:
py-zconfig: update to 3.2.0.

3.2.0 (2017-06-22)
------------------

- Drop support for Python 2.6 and 3.2 and add support for Python 3.6.

- Run tests with pypy and pypy3 as well.

- Host docs at https://zconfig.readthedocs.io

- BaseLoader is now an abstract class that cannot be instantiated.

- Allow ``nan``, ``inf`` and ``-inf`` values for floats in
  configurations. See
  https://github.com/zopefoundation/ZConfig/issues/16.

- Scripts ``zconfig`` (for schema validation) and
  ``zconfig_schema2html`` are ported to Python 3.

- A new ``ZConfig.sphinx`` `Sphinx extension
  \ 
<https://zconfig.readthedocs.io/en/latest/documenting-components.html#documenting-components>`_
  facilitates automatically documenting ZConfig components using their
  description and examples in Sphinx documentation. See
  https://github.com/zopefoundation/ZConfig/pull/25.

- Simplify internal schema processing of max and min occurrence
  values. See https://github.com/zopefoundation/ZConfig/issues/15.

- Almost all uses of ``type`` as a parameter name have been replaced
  with ``type_`` to avoid shadowing a builtin. These were typically
  not public APIs and weren't expected to be called with keyword
  arguments so there should not be any user-visible changes. See
  https://github.com/zopefoundation/ZConfig/issues/17

3.1.0 (2015-10-17)
------------------

- Add ability to do variable substitution from environment variables using
  $() syntax.

3.0.4 (2014-03-20)
------------------

- Added Python 3.4 support.

3.0.3 (2013-03-02)
------------------

- Added Python 3.2 support.

3.0.2 (2013-02-14)
------------------

3.0.1 (2013-02-13)
------------------

- Fix a bug in Python 3 with the custom string `repr()` function.

- Dropped Python 2.4 and 2.5 support.

2.9.3 (2012-06-25)
------------------

- Fixed: port values of 0 weren't allowed.  Port 0 is used to request
  an ephemeral port.

2.9.2 (2012-02-11)
------------------

- Adjust test classes to avoid base classes being considered separate
  test cases by (at least) the "nose" test runner.

2.7.0 (2009-06-11)
------------------

- Added a convenience function, ``ZConfig.configureLoggers(text)`` for
  configuring loggers.

- Relaxed the requirement for a logger name in logger sections,
  allowing the logger section to be used for both root and non-root
  loggers.
