This is a library containing a bunch of routines that I have found useful for setting up and running experiments remotely.
Some of these utilities execute a sequence of steps. They require a shell as input and actually run a command remotely.
The rest only construct a command that can be executed and return it to the caller without executing anything.
There are also some utilities that don't construct or run commands. They are just useful functions for constructing commands.
The centos and ubuntu submodules contain routines specifically useful for those platforms.
