Version information
-------------------
.. data:: __version__
The version of :mod:`pyudev` as string. This string contains a major and a
minor version number, and optionally a revision in the form
``major.minor.revision``. As said, the ``revision`` part is optional and
may not be present.
This attribute is mainly intended for display purposes, use
:data:`__version_info__` to check the version of :mod:`pyudev` in source
code.
.. data:: __version_info__
The version of :mod:`pyudev` as tuple of integers. This tuple contains a
major and a minor number, and optionally a revision number in the form
``(major, minor, revision)``. As said, the ``revision`` component is
optional and may not be present.
