Clap: How to generate completion scripts?

[chevdor]

I am not seeing any where where the completion script is actually generated:

• I don´t see the 'completions' feature that I have seen in some old issues
• no completion seems to be generated when using --release

How does the generation of the completion scripts work ?

After building a simple sample using --release, I get the following:

I should probably add an example to examples dir that explains this. But the details can be found here:

https://docs.rs/clap/2.32.0/clap/struct.App.html#method.gen_completions

I'm going to close this for now, and mark as "after v3 release"

Thanks @kbknapp that´s the link I was missing.
