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.
Any chance of working on a more involved patch which allows this to be set through an environment variable in the Makefile? Would like to try and get something that upstream can accept so we don't need to carry a patch forever. Thanks!
