[mitchell]

=================

[tom_gross]

- Quote path on windows to handle paths with spaces correctly
[tom_gross]

=================

- Sort top_level metadata to avoid error building omelette if they are out of
order. Fixes https://bugs.launchpad.net/collective.buildout/+bug/553005.
Thanks to Leonardo Rochael Almeida.

=================

- Provide an update function (equivalent to install) to avoid spurious "recipe
"doesn't define an update method" warning.
[davisagli]

- Print a warning rather than aborting the buildout if junction.exe is missing
on Windows.
[davisagli]

- Made the tests compatible with a zc.buildout installed with Distribute
rather than Setuptools.
[pumazi]

- Handle OSErrors on symlink and warn the user. MacOSX can raise OSError due
to an existing file here even if os.path.exists returns False.
[MatthewWilkes]

- Include modules from namespace packages in the omelette. (Namespace packages
cannot define anything in __init__.py, but they can contain modules.)
[hathawsh]

- Made the tests compatible with virtualenv.

================

- Adjusted log-levels to be slightly less verbose for non-critical
errors. [malthe]

================

- Fixed 'OSError [Errno 20] Not a directory' on zipped eggs, for
example when adding the z3c.sqlalchemy==1.3.5 egg.
