Repoze.profile

----------------

- Added optional support for directly writing out the profiling data in the
KCacheGrind format.

- Avoid a dependency on `elementtree` when used with Python 2.5 and later.
In those Python versions we used the built-in xml.etree support.

----------------

- ``discard_first_request = true`` did not work!

- Added tests for ``discard_first_request`` and ``flush_at_shutdown``.

- Converted CHANGES.txt to ReST.

- Bump ez_setup.py version.

----------------

- ``discard_first_request = false`` did not work.

- Clearing the profile data from the user interface did not properly
discard profiler state.

----------------

- Initial PyPI release.

----------------

- Remove dependency-link to http://dist.repoze.org to prevent
easy_install from adding that to its search path.

- Incorporated a patch from Alec Flett <alecfmetaweb.com> to uses
``cProfile``, if available, rather than pure Python ``profile``.

- Bump ez_setup.py version.

----------------

- Added compatibility with Python 2.5.

- Made setup.py depend explicitly on ElementTree 1.2.6: meld needs it
but meld isn't a setuptools package.
