Options

Improved error reporting/handling: 

- Added "logical tracebacks" that show functionally what the buildout
  was doing when an error occurs.  Don't show a Python traceback
  unless the -D option is used.

- Added a -D option that causes the buildout to print a traceback and
  start the pdb post-mortem debugger when an error occurs.

Debugging buildouts
===================
Buildouts can be pretty complex. When things go wrong, it isn't
always obvious why. Errors can occur due to problems in user input or
due to bugs in zc.buildout or recipes. When an error occurs, Python's
post-mortem debugger can be used to inspect the state of the buildout
or recipe code were there error occured. To enable this, use the -D
option to the buildout. Let's create a recipe that has a bug:
>>> mkdir(sample_buildout, 'recipes')
>>> write(sample_buildout, 'recipes', 'mkdir.py',
... """
... import os, zc.buildout
...
... class Mkdir:
...
... def __init__(self, buildout, name, options):
... self.name, self.options = name, options
... options['path'] = os.path.join(
... buildout['buildout']['directory'],
... options['path'],
... )
...
... def install(self):
... directory = self.options['directory']
... os.mkdir(directory)
... return directory
...
... def update(self):
... pass
... """)
>>> write(sample_buildout, 'recipes', 'setup.py',
... """
... from setuptools import setup
...
... setup(name = "recipes",

And create a buildout that uses it:
