+# 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
