This action download the latest version of McNeel's standalone YAK tool, also known as the Rhino Package Manager.

You can provide an auth token to allow YAK to push packages to a specific account. YAK will search for this token on a YAK_TOKEN environment variable. Since the naming of the variable in your context may vary, passing a value here will effectively set the YAK_TOKEN env var from that point onward.

This token is obtained by running yak.exe --ci on your local machine.

This is an optional input, as it is only required if you are pushing

The version of YAK that was installed. This is for reference only.

An example of this can be found in the test action

Our own GH_SizeAnalyzer uses this action to build and deploy to the marketplace on every pushed tag.
