The update of the gist was in my to-do list for today ;-)
I would like to keep the the name of the `RevealHelpTransformer` because is reveal-specific... to use with reveal-specific templates... in the future, if I want to use impress.js, I will need a `ImpressHelpTransformer` and impress-specific templates... so.. I feel that we need to keep the identity of the `RevealHelpTransformer`
