# nu-anywhere
# This script injects a Nu Console into a running Cocoa application.
#
# This script must be run as root.
#
# Because paths to the framework and bundle are hard-coded,
# this script must be run from the current directory.
#
# The application must already be running.
#
# Usage: sudo nu-anywhere <application>
#
# Examples: sudo nu-anywhere "Address Book"
# sudo nu-anywhere Safari
#
# Changes for NuSomewhere:
# Changes the load command and the NuConsole bundle so that it reads from the current directory for each.
# Also adds injection of the NuInspect bundle.
