What Does tools.trace Do?
A very basic tutorial for a rather simple library: tools.trace
The easiest way to get up and running is to install leiningen to get your REPL up and running and nrepl.el to connect to it from emacs where you can then navigate to src/what_does_tools_trace_do/core.el and C-M-f C-x C-e
to your heart's content.
If you have other getting started tips, feel free to send me a pull request. :)
