 Run commands across a set of hosts interactively!
+=================================================
+
+Basic configuration file is in multiball.cfg.example in the distribution. Customize to your liking. Host list is loaded from,
+by default, your ssh configuration (assuming you have a specific ssh configuration for your all hosts like Autonomic has). You
+can also use arbitrary host lists (documented in configuration file).

+Planned features, see __main__.py's comments.
