Hundreds of functions of a variety of topics, from statistics to string parsing, module utilities to network tools.
Everyone's pet library accumulates features over time. My erlang library got big, fast. I often find myself giving functions from it out to other people, and a lot of my other libraries are dependant on ScUtil in various ways, so I figured what the hell, let's give it away.
This library is believed to be efficiently implemented at all points. Efficiency tips are, however, both appreciated and taken seriously.
ScUtil uses the TestErl library for unit, regression and stochastic testing.
ScUtil is free and MIT licensed, because the GPL is evil.
ScUtil is written by John Haugeland, from http://fullof.bs/ .
