* The buildout script generated by bootstrap honors more of the settings
in the designated configuration file (e.g., buildout.cfg).
Bugs fixed:
- The handling and documenting of default buildout options was normalized.
This means, among other things, that ``bin/buildout -vv`` and
``bin/buildout annotate`` correctly list more of the options.

command-line assignments. We've discussed most of these options
already, but let's review them and touch on some we haven't discussed:
allow-hosts
On some environments the links visited by `zc.buildout` can be forbidden by
paranoid firewalls. These URLs might be in the chain of links visited by
`zc.buildout` as defined by buildout's `find-links` option, or as defined
by various eggs in their `url`, `download_url`, `dependency_links` metadata.
The fact that package_index works like a spider and might visit links and
go to other locations makes this even harder.
The `allow-hosts` option provides a way to prevent this, and
works exactly like the one provided in `easy_install`.
You can provide a list of allowed host, together with wildcards::
[buildout]
...
allow-hosts =
*.python.org
example.com
All URLs that does not match these hosts will not be visited.
allow-picked-versions
By default, the buildout will choose the best match for a given requirement
if the requirement is not specified precisely (for instance, using the
"versions" option. This behavior corresponds to the
"allow-picked-versions" being set to its default value, "true". If
"allow-picked-versions" is "false," instead of picking the best match,
buildout will raise an error. This helps enforce repeatability.

Locations can be urls::
[buildout]
...
find-links = http://download.zope.org/distribution/

A download cache can be used as the basis of application source releases.
In an application source release, we want to distribute an application that
can be built without making any network accesses. In this case, we
distribute a buildout with download cache and tell the buildout to install
from the download cache only, without making network accesses. The
buildout install-from-cache option can be used to signal that packages
should be installed only from the download cache.

newest
By default buildout and recipes will try to find the newest versions of
distributions needed to satisfy requirements. This can be very time
consuming, especially when incrementally working on setting up a buildout
or working on a recipe. The buildout "newest" option can be used to to
suppress this. If the "newest" option is set to false, then new
distributions won't be sought if an installed distribution meets
requirements. The "newest" option can also be set to false using the -N
command-line option. See also the "offline" option.
offline
The "offline" option goes a bit further than the "newest" option. If the
buildout "offline" option is given a value of "true", the buildout and
recipes that are aware of the option will avoid doing network access. This
is handy when running the buildout when not connected to the internet. It
also makes buildouts run much faster. This option is typically set using
the buildout -o option.
parts

parts-directory

prefer-final
Currently, when searching for new releases, the newest available
release is used. This isn't usually ideal, as you may get a
development release or alpha releases not ready to be widely used.
You can request that final releases be preferred using the prefer
final option in the buildout section::

prefer-final = true
When the prefer-final option is set to true, then when searching for
new releases, final releases are preferred. If there are final
releases that satisfy distribution requirements, then those releases
are used even if newer non-final releases are available. The buildout
prefer-final option can be used to override this behavior.
In buildout version 2, final releases will be preferred by default.

newest releases.

This follows the policy followed by setuptools itself. Experience shows
this policy to to be inconvenient. Zipped eggs make debugging more
difficult and often import more slowly. You can include an unzip option in
the buildout section to change the default unzipping policy ("unzip =
true").
