"""Store version info for this BE installation.

By default, use the Git-generated information in
:py:mod:`~libbe._version`, but allow manual overriding by setting
:py:data:`libbe.version._VERSION`.  This allows support of both the "I
don't want to be bothered setting version strings" and the "I want
complete control over the version strings" workflows.
