customise template instantiation

[spdegabrielle]

Extend raco new to support additional arguments to customise template instantiation
e.g. renaming main.scrbl to $PACKAGE-NAME.scrbl

extension options:

• 'template variables' using e.g. scribble/text
• Maybe the raco new(prev raco from-template) command could look for some optional .from-template.rkt code in the template, and if found, run it.
• raco scaffold already has sophisticated facilities to generate code https://docs.racket-lang.org/scaffold/

How about having prompts at the terminal to change different options? Something similar to when you run npm init and you change a bunch of settings for your project. Can add a -i flag to tell it when to interactively let you change certain things.

That is a great idea!

I think 'charterm' will be helpful for interactive prompt stuff.

Sounds good! I'm getting started on this now 👍

After taking a very brief look at charterm, I think that'll be a little overkill for this honestly...
