"""
Current Fabric version constant plus version pretty-print method.

This functionality is contained in its own module to prevent circular import
problems with ``__init__.py`` (which is loaded by setup.py during installation,
which in turn needs access to this version information.)

    Return a version string for this package, based on `VERSION`.

    Takes a single argument, ``form``, which should be one of the following
    strings:

    * ``branch``: just the major + minor, e.g. "0.9", "1.0".
    * ``short`` (default): compact, e.g. "0.9rc1", "0.9.0". For package
      filenames or SCM tag identifiers.
    * ``normal``: human readable, e.g. "0.9", "0.9.1", "0.9 beta 1". For e.g.
      documentation site headers.
    * ``verbose``: like ``normal`` but fully explicit, e.g. "0.9 final". For
      tag commit messages, or anywhere that it's important to remove ambiguity
      between a branch and the first final release within that branch.
    * ``all``: Returns all of the above, as a dict.
