Always unzipping eggs

=====================

By default, zc.buildout doesn't unzip zip-safe eggs.

    >>> write('buildout.cfg',

    ... '''

    ... [buildout]

    ... parts = eggs

    ... find-links = %(link_server)s

    ...

    ... [eggs]

    ... recipe = zc.recipe.egg

    ... eggs = demo

    ... ''' % globals())

    >>> _ = system(buildout)

    >>> ls('eggs')

    -  demo-0.4c1-py2.4.egg

    -  demoneeded-1.2c1-py2.4.egg

    d  setuptools-0.6c8-py2.4.egg

    -  zc.buildout.egg-link

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.

    >>> write('buildout.cfg',

    ... '''

    ... [buildout]

    ... parts = eggs

    ... find-links = %(link_server)s

    ... unzip = true

    ...

    ... [eggs]

    ... recipe = zc.recipe.egg

    ... eggs = demo

    ... ''' % globals())

    >>> import os

    >>> for name in os.listdir('eggs'):

    ...     if name.startswith('demo'):

    ...         remove('eggs', name)

    >>> _ = system(buildout)

    >>> ls('eggs')

    d  demo-0.4c1-py2.4.egg

    d  demoneeded-1.2c1-py2.4.egg

    d  setuptools-0.6c8-py2.4.egg

    -  zc.buildout.egg-link
