Hey, I have been hacking on HyperTag over the last few days. I am keen on feedback and potential contributors.

From the README: What is the point of HyperTag's existence? HyperTag offers some unique features such as the import function that make it very convenient to use. Also HyperTag's code base is written in Python and thus extremely small (<500 LOC) compared to TMSU (>10,000 LOC) and SuperTag (>25,000 LOC), making it very easy to modify / extend / fix it yourself.
