# Makefile module to deploy tfkit
#
# Will add bin/tfkit_init utility, and use it to guess URI to tfkit.git,
# and clone tfkit to current directory.
#
# Adds targets: test to run tfkit tests, tfkit to deploy tfkit, tfkit_update to
# pull tfkit updates, and tfkit_delete to remove the tfkit code.
#
# NOTE: Do not edit this file in your project directory as it will overwrite
#       itself when you call tfkit_update!!!
