Provide list{addresses,aliases,users,relocated} subcommands The patch provides the list{addresses,aliases,users,relocated} subcommands to the UI. All commands actually take the same path in the code and only one query is run with different parameters for each case. There are still two shortcomings: 1. With alias domains, the output order is not as one might want it, e.g. foo@example.org bar@example.org foo@example.com bar@example.com when it should really be foo@ twice and then bar@ twice. I have not found a way to modify the SQL accordingly. 2. The SELECT queries for Accounts, Alias and Relocated are hard-coded in common.py.

:mod:`VirtualMailManager` ---  Initialization code and some functions
=====================================================================

.. module:: VirtualMailManager
  :synopsis: Initialization code and some functions

.. moduleauthor:: Pascal Volk <neverseen@users.sourceforge.net>

.. toctree::
   :maxdepth: 2

When the VirtualMailManager module, or one of its sub modules, is imported,
the following actions will be performed:

  - :func:`locale.setlocale` (with :const:`locale.LC_ALL`) is called, to set
    :const:`ENCODING`
  - :func:`gettext.install` is called, to have 18N support.

Constants and data
------------------

.. data:: ENCODING

  The systems current character encoding, e.g. ``'UTF-8'`` or
  ``'ANSI_X3.4-1968'`` (aka ASCII).


Functions
---------

.. function:: ace2idna(domainname)

  Converts the idn domain name *domainname* into punycode.

  :param domainname: the domain-ace representation (``xn--…``)
  :type domainname: str
  :rtype: unicode

.. function:: check_domainname(domainname)

  Returns the validated domain name *domainname*.

  It also converts the name of the domain from IDN to ASCII, if necessary.

  :param domainname: the name of the domain
  :type domainname: :obj:`basestring`
  :rtype: str
  :raise VirtualMailManager.errors.VMMError: if the domain name is
    too long or doesn't look like a valid domain name (label.label.label).

.. function:: check_localpart(localpart)

  Returns the validated local-part *localpart* of an e-mail address.

  :param localpart: The local-part of an e-mail address.
  :type localpart: str
  :rtype: str
  :raise VirtualMailManager.errors.VMMError: if the local-part is too
    long or contains invalid characters.

.. function:: exec_ok(binary)

  Checks if the *binary* exists and if it is executable.

  :param binary: path to the binary
  :type binary: str
  :rtype: str
  :raise VirtualMailManager.errors.VMMError: if *binary* isn't a file
    or is not executable.

.. function:: expand_path(path)

  Expands paths, starting with ``.`` or ``~``, to an absolute path.

  :param path: Path to a file or directory
  :type path: str
  :rtype: str

.. function:: get_unicode(string)

  Converts `string` to `unicode`, if necessary.

  :param string: The string taht should be converted
  :type string: str
  :rtype: unicode

.. function:: idn2ascii(domainname)

  Converts the idn domain name *domainname* into punycode.

  :param domainname: the unicode representation of the domain name
  :type domainname: unicode
  :rtype: str

.. function:: is_dir(path)

  Checks if *path* is a directory.

  :param path: Path to a directory
  :type path: str
  :rtype: str
  :raise VirtualMailManager.errors.VMMError: if *path* is not a directory.


Examples
--------

  >>> from VirtualMailManager import *
  >>> ace2idna('xn--pypal-4ve.tld')

  >>> check_domainname(u'pаypal.tld')
  'xn--pypal-4ve.tld'
  >>> check_localpart('john.doe')
  'john.doe'
  >>> exec_ok('usr/bin/vim')
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "./VirtualMailManager/__init__.py", line 93, in exec_ok
      NO_SUCH_BINARY)
  VirtualMailManager.errors.VMMError: 'usr/bin/vim' is not a file
  >>> exec_ok('/usr/bin/vim')
  '/usr/bin/vim'
  >>> expand_path('.')
  '/home/user/hg/vmm'
  >>> get_unicode('hello world')
  u'hello world'
  >>> is_dir('~/hg')
