Announcing a new utility: 'trace'

The argument names could be useful, just as the name/pid (timing) prefix could be useful. Both could be optional. One thing that I really like about strace is that it defaults to being pretty terse. Pids are only included if tracing children is enabled, timing information is a whole set of options depending on what type of timing you need, etc. That way the simple case of just seeing what system calls are bing made isn't clouded by extra information. (Am I in the event loop or stuck on a futex?)
