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.
ScUtil is currently being converted from old code to new code, to take better advantage of newly available tools, to strip the cruft that came from early naïve language problems, to provide more rigorous testing, and so forth. It will be release quality when the project tracker reaches 1.0, but I'm releasing it now to support dependencies, to get feedback and to encourage bug reports.
This library is believed to be efficiently implemented at all points. Efficiency tips are, however, both appreciated and taken seriously.
ScUtil is free and MIT licensed, because the GPL is evil.
