Mac OS X temp files in release 0.6.2?

Hi,

While unpacking radiant-0.6.2 I noticed some (temp?) files that seem
to be generated on a Mac OS X and are not present in the official
repository.

I assume these were included in the release by ‘accident’?:

radiant-0.6.2/._CHANGELOG
radiant-0.6.2/._CONTRIBUTORS
radiant-0.6.2/._Rakefile
radiant-0.6.2/app/controllers/._application.rb
etc…

Best regards,

Jeroen J.
