Standard installation
==============================

Once all the prerequisites are satisfied, ARS can be installed in any of these
simple alternatives. **To install ARS we recommend you to use pip**.

**pip**

It "is a tool for installing and managing Python packages, such as those found
in the Python Package Index. It’s a replacement for easy_install."
(`pip-installer.org <http://www.pip-installer.org/>`_)

This program is not part of standard Python installations. However, it is
widely used because it has ``easy_install``'s functionality plus uninstall and
upgrade features.
::

   pip install ARS


**Easy Install**

It "is a Python module (``easy_install``) bundled with ``setuptools`` that lets
you automatically download, build, install, and manage Python packages."
(`packages.python.org/distribute
<http://packages.python.org/distribute/easy_install.html>`_)
::

   easy_install ARS


**setup.py install**

This is the standard way to install a module distribution.
It uses the official and built-in ``distutils`` package.

For this, you need to `download ARS <http://pypi.python.org/pypi/ARS/>`_,
extract the contents from the archive (e.g. ``.zip``, ``.tar.bz2``),
and run (from its root directory)::

   python setup.py install
