src 0.7

[src](http://www.catb.org/~esr/src/) is a simple revision control system “with a modern UI for single-file solo projects kept possibly more than one to a directory”. This is a new RCS-like by Eric S. Raymond, still in its early stage (first release less than a week ago).

It has been on [HN](https://news.ycombinator.com/item?id=8601727)’s homepage for a couple hours now.
Done. The reasoning behind that is that `python` should be a symlink to `python2` or `python3`, which themselves are symlinks to more specific versions (e.g. `python2.7`/`python3.4`).

`src` has planned support for both Python 2 and Python 3, which will allow them to use `python` instead of `python2`. There’s a patch, but it fails their regression tests for now.
