""" | ||
ReST directive for embedding Youtube and Vimeo videos. | ||
There are two directives added: ``youtube``. The only | ||
argument is the video id of the video to include. | ||
Both directives have three optional arguments: ``height``, ``width`` | ||
and ``align``. Default height is 281 and default width is 500. | ||
Example:: | ||
.. youtube:: anwy2MPT5RE | ||
:height: 315 | ||
:width: 560 | ||
:align: left | ||
