# Restart a rack app running under pow
 # http://pow.cx/
 #
 # Adds a kapow command that will restart an app
 #
 #   $ kapow myapp
 #
 # Supports command completion.
 #
 # If you are not already using completion you might need to enable it with
 # 
 #    autoload -U compinit compinit
 #

 # Changes:

 #

 # Defaults to the current application, and will walk up the tree to find 
 # a config.ru file and restart the corresponding app
 #
 # Will Detect if a app does not exist in pow and print a (slightly) helpful 
 # error message
