runsteps

A controlled sequential command runner.

What does that mean? Given a series of commands, perhaps a directory of shell scripts, and a mechanism for specfying the order of those commands, runsteps will execute them and monitor them for state and failure.

More specifically, runsteps collects running times, output and return codes of each executed step and controls the environment variables of the step. A mechanism for any step to 'save' key value pairs for use as environment variables in following steps is also provided. This allows the steps to 'share' small bits of data between themselves as the entire run progresses.
