Remove unused buildout. Replace distutils with distribute.

Remove unused buildout. Replace distutils with distribute.

[Gary Poster (gary)]

Great! Thank you.

Rather than copying over ez_setup.py from Launchpad, I suggest using the distribute version. http://packages.python.org/distribute/using.html describes details very roughly. http://python-distribute.org/distribute_setup.py

Moreover, see this discussion, and contain your weeping. And talk to barry if you want to. http://old.nabble.com/to-distribute_setup()-or-not,-that-is-the-question-td33210691.html I kind of like Piotr's approach in that thread:

import sys
try:
   import setuptools
except ImportError:
   if '--download-distribute' in sys.argv:
    import distribute_setup
        distribute_setup.use_setuptools()
   else:
       print >>sys.stderr, 'Please install distribute or add --download-distribute argument'"
       exit(1)

He didn't get a reply though.

Did I mention the idea about running away?

review: Approve

[Brad Crittenden (bac)]

Gary thanks for the review. Unfortunately I didn't see your suggestions and toggled the review to 'Approved', which caused tarmac to automatically land it. I've moved it back to 'WIP', will push the changes using your suggestions, will go back to 'Approved' and see if tarmac will re-land.

Replace ez_setup with distribute_setup

35. By Brad Crittenden on 2012-06-26

Cleaned up some lint so that we can run pocketlint as a pre-commit hook.

[Brad Crittenden (bac)]

Changes made, except for the suggestion from Piotr.

+"""Bootstrap distribute installation
+
+If you want to use setuptools in your package's setup.py, just include this
+file in the same directory with it, and add this to the top of your setup.py::
+
+    from distribute_setup import use_setuptools
+    use_setuptools()
+
+If you want to require a specific version of setuptools, set a download
+mirror, or use an alternate download directory, you can do so by supplying
+the appropriate options to ``use_setuptools()``.
+
+This file can also be run as a script to install or upgrade setuptools.
