# Top level Makefile for the entire project
#
# This Makefile encodes the "go generate" prerequeisites ensuring that the proper tooling is installed and
# that the generate steps are executed when their prerequeisites files change.
#
# This Makefile follows a few conventions:
#
#    * All cmds must be added to this top level Makefile.
#    * All binaries are placed in ./bin, its recommended to add this directory to your PATH.
#    * Each package that has a need to run go generate, must have its own Makefile for that purpose.
#    * All recursive Makefiles must support the all and clean targets
#

# SUBDIRS are directories that have their own Makefile.
# It is required that all subdirs have the `all` and `clean` targets.
