paths to set up a custom interpreter part that has the distributions
or parts in the path. For example::

New features: New features:
- The buildout init command now accepts distribution requirements and
paths to set up a custom interpreter part that has the distributions

python bootstrap.py init BeautifulSoup
- Added buildout:socket-timout option so that socket timeout can be configured - Added buildout:socket-timout option so that socket timeout can be configured
both from command line and from config files. (gotcha) both from command line and from config files. (gotcha)

When using the ``init`` command, you can specify distribution requirements
or paths to use:
>>> cd(sample_bootstrapped)
>>> remove('setup.cfg')
>>> remove('bin', 'buildout')
>>> print system(buildout + ' -csetup.cfg init demo other ./src'),

This causes a ``py`` part to be included that sets up a custom python
interpreter with the given requirements or paths:
>>> cat('setup.cfg')
[buildout]
parts = py
<BLANKLINE>
[py]
recipe = zc.recipe.egg
interpreter = py
eggs =
demo
other
extra-paths =
./src
Passing requirements or paths causes the the builout to be run as part
of initialization. In the example above, we got a number of
distributions installed and 2 scripts generated. The first, ``demo``,
was defined by the ``demo`` project. The second, ``py`` was defined by
the generated configuration. It's a "custom interpreter" that behaves
like a standard Python interpeter, except that includes the specified
eggs and extra paths in it's Python path.
We specified a source directory that didn't exist. Buildout created it
for us:
>>> ls('.')
- .installed.cfg
d bin
d develop-eggs
d eggs
d parts
- setup.cfg
d src
>>> uncd()
.. Make sure it works if the dir is already there:
>>> cd(sample_bootstrapped)
>>> _ = system(buildout + ' -csetup.cfg buildout:parts=')
>>> remove('setup.cfg')
>>> print system(buildout + ' -csetup.cfg init demo other ./src'),
