Sanity Check
============

Imports::

    >>> import email
    >>> import pkginfo
    >>> from distutils.dist import Distribution
    >>> from StringIO import StringIO

Representative metadata::

    >>> attrs = dict(name='name', version='0.0', description='description', url='http://example.org')

Make a distribution::

    >>> distribution = Distribution(attrs)
    >>> buffer = StringIO()
    >>> distribution.metadata.write_pkg_file(buffer)
    >>> pkginfo_dist = pkginfo.Distribution()
    >>> pkginfo_dist.parse(buffer.getvalue())
    >>> newattrs = dict([(i, getattr(pkginfo_dist, i)) for i in pkginfo_dist])
    >>> newattrs['name'] == 'name'
    True
    >>> newattrs['home_page'] == 'http://example.org'
    True

Convert to email::

    >>> message = email.message.Message()
    >>> for key, value in newattrs.items():
    ...     message[key] = value
    >>> message.keys()
    >>> message.items()
