    A new version of the Python module which wraps GnuPG has been
    released.

    What Changed?
    =============
    This is a minor enhancement and bug-fix release. See the project
    website ( http://code.google.com/p/python-gnupg/ ) for more
    information. Summary:

    Better support for status messages from GnuPG.
    Support for additional arguments to be passed to GnuPG.
    Bugs in tests which used Latin-1 encoded data have been fixed by
    specifying that encoding.
    On verification (including after decryption), the signer trust level
    is returned in integer and text formats.

    The current version passes all tests on Windows (CPython 2.4, 2.5,
    2.6, 2.7, 3.1 and Jython 2.5.1), Mac OS X (Python 2.5) and Ubuntu
    (CPython 2.4, 2.5, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11
    has been used for the tests.

    What Does It Do?
    ================
    The gnupg module allows Python programs to make use of the
    functionality provided by the Gnu Privacy Guard (abbreviated GPG or
    GnuPG). Using this module, Python programs can encrypt and decrypt
    data, digitally sign documents and verify digital signatures, manage
    (generate, list and delete) encryption keys, using proven Public Key
    Infrastructure (PKI) encryption technology based on OpenPGP.

    This module is expected to be used with Python versions >= 2.4, as it
    makes use of the subprocess module which appeared in that version of
    Python. This module is a newer version derived from earlier work by
    Andrew Kuchling, Richard Jones and Steve Traugott.

    A test suite using unittest is included with the source distribution.

    Simple usage:

    >>> import gnupg
    >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')
    >>> gpg.list_keys()

    [{
    ...
    'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',
    'keyid': '197D5DAC68F1AAB2',
    'length': '1024',
    'type': 'pub',
    'uids': ['', 'Gary Gross (A test user) <>']},
    {
    ...
    'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
    'keyid': '0C5FEFA7A921FC4A',
    'length': '1024',
    ...
    'uids': ['', 'Danny Davis (A test user) <>']}]
    >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
    >>> str(encrypted)

    '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n
    \nhQIOA/6NHMDTXUwcEAf
    ....
    -----END PGP MESSAGE-----\n'
    >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')
    >>> str(decrypted)

    'Hello, world!'
    >>> signed = gpg.sign("Goodbye, world!", passphrase='secret')
    >>> verified = gpg.verify(str(signed))
    >>> print "Verified" if verified else "Not verified"

    'Verified'

    patches and suggestions for improvement). Enjoy!
