"""
Script for installation and distribution.

You can use environment variable `NNI_RELEASE` to set release version.

If release version is not set, default to a development build whose version string will be `999.dev0`.


## Development ##

Build and install for development:

  $ python setup.py develop

Uninstall:

  $ pip uninstall nni

Remove generated files: (use "--all" to remove toolchain and built wheel)

  $ python setup.py clean [--all]

Build TypeScript modules without install:

  $ python setup.py build_ts


## Release ##

Build wheel package:

  $ NNI_RELEASE=2.0 python setup.py build_ts
  $ NNI_RELEASE=2.0 python setup.py bdist_wheel -p manylinux1_x86_64

Where "2.0" is version string and "manylinux1_x86_64" is platform.
The platform may also be "macosx_10_9_x86_64" or "win_amd64".

`build_ts` must be manually invoked before `bdist_wheel`,
or setuptools cannot locate JS files which should be packed into wheel.
