"""Youtube-dlg setup file.

Examples:
    Windows::

        python setup.py py2exe

    Linux::

        python setup.py install

    Build source distribution::

        python setup.py sdist

    Build platform distribution::

        python setup.py bdist

    Build the translations::

        python setup.py build_trans

    Build with updates disabled::

        python setup.py build --no-updates

Requirements:

    * GNU gettext utilities

Notes:
    If you get 'TypeError: decoding Unicode is not supported' when you run
    py2exe then apply the following patch::

        http://sourceforge.net/p/py2exe/patches/28/

    Basic steps of the setup::

        * Run pre-build tasks
        * Call setup handler based on OS & options
            * Set up hicolor icons (if supported by platform)
            * Set up fallback pixmaps icon (if supported by platform)
            * Set up package level pixmaps icons (*.png)
            * Set up package level i18n files (*.mo)
            * Set up scripts (executables) (if supported by platform)
        * Run setup
