Pepperfish profiler was the only one I could use that was pure lua,
working with 5.1, single file, and produced a useful output without
having to hack it in any way.

The problem I have is that the output is too verbose and it is hard to
follow. It would be awesome to produce a dot file for graphviz to
produce the same results as google perf, for instance [1]. Or even
pure text output a little more structured, like ruby-prof does [2],
[3].
