Supported targets: prepare, develop, docs, dist, clean, test, docker, and push_docker.

Please note that all build targets require a virtualenv to be active.

The 'prepare' target installs Toil's build requirements into the current virtualenv.

The 'develop' target creates an editable install of Toil and its runtime requirements in the
current virtualenv. The install is called 'editable' because changes to the source code
immediately affect the virtualenv. Set the 'extras' variable to ensure that the 'develop' target
installs support for extras; some tests require extras to be installed. Consult setup.py for the
list of supported extras. To install Toil in develop mode with all extras, run

	make develop extras=[all]

The 'dist' target creates a source distribution and a wheel of Toil. It is used
for some unit tests and for installing the currently checked out version of Toil
into the appliance image.

The 'clean' target cleans up the side effects of 'develop', 'dist', 'docs', and 'docker'
on this machine. It does not undo externally visible effects like removing packages already
uploaded to PyPI.

The 'docs' target uses Sphinx to create HTML documentation in the docs/_build directory

Targets are provided to run Toil's tests. Note that these targets do *not* automatically install
Toil's dependencies; it is recommended to 'make develop' before running any of them.

The 'test' target runs Toil's unit tests in parallel with pytest. It will run some docker tests and
setup. Note: this target does not capture output from the terminal. For any of the test targets,
set the 'tests' variable to run a particular test, e.g.

	make test tests=src/toil/test/sort/sortTest.py::SortTest::testSort
    
The 'cov' variable can be set to '' to suppress the test coverage report.
    
The 'test_offline' target is similar, but runs only tests that don't need
Internet or Docker by default.  The 'test_offline' target takes the same
arguments as the 'test' target.

    make test_offline tests=src/toil/test/src/threadingTest.py

The 'docker' target builds the Docker images that make up the Toil appliance. You may set the
TOIL_DOCKER_REGISTRY variable to override the default registry that the 'push_docker' target pushes
the appliance images to, for example:

	TOIL_DOCKER_REGISTRY=quay.io/USER make docker

You might also want to build just for one architecture and load into your
Docker daemon. We have a 'load_docker' target for this.

    make load_docker arch=linux/amd64

If Docker is not installed, Docker-related targets tasks and tests will be skipped. The
same can be achieved by setting TOIL_DOCKER_REGISTRY to an empty string.

The 'push_docker' target pushes the Toil appliance images to a remote Docker registry. It
requires the TOIL_DOCKER_REGISTRY variable to be set to a value other than the default to avoid
accidentally pushing to the official Docker registry for Toil.

The TOIL_DOCKER_NAME environment variable can be set to customize the appliance image name that
is created by the 'docker' target and pushed by the 'push_docker' target.
