''' Provide a version for the Bokeh library.

This module uses `versioneer`_ to manage version strings. During development,
`versioneer`_ will compute a version string from the current git revision.
For packaged releases based off tags, the version string is hard coded in the
files packaged for distribution.

Attributes:
    __version__:
        The full version string for this installed Bokeh library

Functions:
    base_version:
        Return the base version string, without any "dev", "rc" or local build
        information appended.
