    <para>The Debian OpenStack packages are maintained on Debian Sid
      (also known as Debian Unstable) - the current development
      version. Backported packages run correctly on Debian Wheezy with
      one caveat:</para>
    <para>All OpenStack packages are written in Python. All packages
      support version 2.7; porting to Python version 3 is ongoing.
      Note that Debian Wheezy uses
      Python 2.6 and 2.7, with Python 2.7 as the default interpreter;
      Sid has only Python 2.7. There is one packaging change between
      these two. In Python 2.6, you installed the
        <package>python-argparse</package> package separately. In
      Python 2.7, this package is installed by default. Unfortunately,
      in Python 2.7, this package does not include <code>Provides:
        python-argparse</code> directive.</para>
    <step>
    <para>Because the packages are maintained in Sid where the
        <code>Provides: python-argparse</code> directive causes an
      error, and the Debian OpenStack maintainer wants to maintain one
      version of the OpenStack packages, you must manually install the
        <package>python-argparse</package> on each OpenStack system
      that runs Debian Wheezy before you install the other OpenStack
      packages. Use the following command to install the
      package:</para>
    <screen><prompt>#</prompt> <userinput>apt-get install python-argparse</userinput></screen>
    <para>This caveat applies to most OpenStack packages in
      Wheezy.</para>
