#
# Include this Makefile in your project to pull in the Nerves versions
# of all of the build tools.
#
# NOTE: If you source nerves-env.sh, then including this script is not
# necessary. Basically, the rule is to do one or the other. Sourcing
# nerves-env.sh has the advantage that the environment is set properly
# on the commandline should you need to run commands manually.
