# This Makefile is used by the developer. It is not needed in any way to build
# a checkout of the neXGB repository.
# It will be useful, however, if you are hacking at the code generator.
# i.e., after making a change to the code generator, run 'make' in the
# xgb directory. This will build xgbgen and regenerate each sub-package.
# 'make test' will then run any appropriate tests (just tests xproto right now).
# 'make bench' will test a couple of benchmarks.
# 'make build-all' will then try to build each extension. This isn't strictly
# necessary, but it's a good idea to make sure each sub-package is a valid
# Go package.
