Show details about the installed library.

The ``version`` supports `Semantic Versioning <http://semver.org>`_ (
``<major>.<minor>.<patch>``) and can take any of the following forms:

* ``0.1.2`` - an exact version number. Use only this exact version
* ``^0.1.2`` - any compatible version (exact version for ``0.x.x`` versions
* ``~0.1.2`` - any version with the same major and minor versions, and an
  equal or greater patch version
* ``>0.1.2`` - any version greater than ``0.1.2``. ``>=``, ``<``, and ``<=``
  are also possible
* ``>0.1.0,!=0.2.0,<0.3.0`` - any version greater than ``0.1.0``, not equal to
  ``0.2.0`` and less than ``0.3.0``
