# 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
