long_description = """*A Python interface to UNIDATA's UDUNITS-2 library with CF
extensions*

**Note: Versions 3.0.0 and later are only compatible with version Python 3. Use version 1.9 for Python 2 compatibility.**

Store, combine and compare physical units and convert numeric values
to different units.

Units are as defined in `UNIDATA's UDUNITS-2 library
<http://www.unidata.ucar.edu/software/udunits/>`_, except for
reference time units (such as ``'days since 2000-12-1'`` in the
``'proleptic_gregorian'`` calendar), which are handled by the `cftime
python package <https://pypi.python.org/pypi/cftime>`_.

In addition, some units are either new to, modified from, or removed
from the standard UDUNITS-2 database in order to be more consistent
with the `CF conventions <http://cfconventions.org/>`_.
