@kingledion
Thank you for the first contribution.

While this change would do its bit, I think the main issue is CLI does not infer the kind automatically.
And I confirmed that .rs extension is not considered in CLI.
https://github.com/apache/openwhisk-cli/blob/master/commands/action.go#L58

Do you have an interest in fixing the CLI instead?

[rabbah]

I propose we can accept this doc update until the cli is patched.

[dgrove-oss]

Agreed; let's update the docs with the workaround, fix the cli, release the cli, then revert the doc update.

[style95]

Got it.
