 Run commands across a set of hosts interactively!
 =================================================
 
-Basic configuration file is in `multiball.cfg.example` in the distribution. Customize to your liking. 
+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.

-- keep track of previous command outputs for last command, and any previous command with target list and command line
-- calling commands and alieses from command line
-- tagging and filtering commands (so oupgrade gets a tag, and we can filter them)
-- saving the last host set in a .file
-- allow server groups
-- allow grepping of output from a command, and then populating the target list from matchintg on it
-- add 'watch' to run a command repeatedly until it succeeds (interruptable)
-- add the number of servers for each group of services too
-- notice when you don't sudo in front of command and it errors and ask you if you meant to sudo
-- autocomplete for environment variable names (requires heirarchical completer)
-- implement target aliases (-filteralias) which gives a label to an argument to -hosts
-- ad-hoc host groupings with assigned names, and a host grouping stack
-- Assign each output group to a number that can be easily selected with a -target etc. But also allow matching
-  against those groups. Output groupings survive until the next command.
-- allow scripts that use -safe to prompt for safety / restore safety after running
-- Add variables that can be set and passed to commands
-- implement various commented commands in the command list
-- implement interactive alias system
-- Catch more exceptions in fabtools, and also add retries
-- Make the runner aware of multiple commands so that it can combine outputs and make 'overall success' or 'overall failure'
-- make C-c break the connections not the program
-- make a /summary command that *only* outputs the summary of a remote command, not the stdout/stderr
