** Development version **

Features:
- Version checks can now be carried out against the following source code
  configuration tools and repositories:
  - PyPI
  - GitHub
  - Git (a local (offline) repository)
- The Git tag is now obtained using the ls-remote tool which is flexible
  to both directory paths (for local repositories) and URLs (for GitHub).
- The version of an *installed* library can be checked rather than using
  the _version.py file.
