# 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.
#
#    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.
