!/bin/bash

1. Run all examples
2. Update verison number in railib/__init__.py
3. Tag the repo with the version number:
$ git tag <version>
$ git push origin --tags
4. Run ./release-build, make sure no issues
5. Run this script
6. Verify that the expected version appears on https://pypi.org

In order to upload to PyPI you will need to login to https://pypi.org,
using credentials that IT can provide, and create an API Token in the
rai-sdk project. Then you need to create a $HOME/.pypirc file that looks
like the following:

~~~
[distutils]
index-servers =
pypi

[pypi]
username = __token__
password = <API Token>
[rai-sdk]
username = __token__
password = <API Token>
~~~

The upload script will error on the .egg file, you you can ignore, the error
is benign.

Note, the script requires twine: `pip install twine`

set -ex

./release-build

./release-upload
