## Basic targets.
##
##   This Makefile wraps basic build and test targets for ease-of-use. Bazel
##   is run inside a canonical Docker container in order to simplify up-front
##   requirements.
##
##   There are common arguments that may be passed to targets. These are:
##     STARTUP_OPTIONS - Bazel startup options.
##     OPTIONS - Build or test options.
##     TARGETS - The bazel targets.
##     ARGS    - Arguments for run or sudo.
##
##   Additionally, the copy target expects a DESTINATION to be provided.
##
##   For example, to build runsc using this Makefile, you can run:
##     make build OPTIONS="" TARGETS="//runsc"'
##
help: ## Shows all targets and help from the Makefile (this message).

				printf "%s\n", $$2; \
			} \
		}'
build: ## Builds the given $(TARGETS) with the given $(OPTIONS). E.g. make build TARGETS=runsc
test:  ## Tests the given $(TARGETS) with the given $(OPTIONS). E.g. make test TARGETS=pkg/buffer:buffer_test
copy:  ## Copies the given $(TARGETS) to the given $(DESTINATION). E.g. make copy TARGETS=runsc DESTINATION=/tmp
run:   ## Runs the given $(TARGETS), built with $(OPTIONS), using $(ARGS). E.g. make run TARGETS=runsc ARGS=-version
sudo:  ## Runs the given $(TARGETS) as per run, but using "sudo -E". E.g. make sudo TARGETS=test/root:root_test ARGS=-test.v

## Docker image targets.
##
##   Images used by the tests must also be built and available locally.
##   The canonical test targets defined below will automatically load
##   relevant images. These can be loaded or built manually via these
##   targets.
##
##   (*) Note that you may provide an ARCH parameter in order to build
##   and load images from an alternate archiecture (using qemu). When
##   bazel is run as a server, this has the effect of running an full
##   cross-architecture chain, and can produce cross-compiled binaries.
