Repo-Types - Awesome !

[Marc Weber]

Hi,

I was looking for a way to add the repository location to .cabal files.
I found the existing implementation.

However it's very likely that this new feature is missed.
So what about showing a note when runinng sdist or such?

Eg

Note: You haven't specified a repository location.
You should specify a repository location so that others can
check latest changes before writing a patch. Duplicating efforts can be
avoided. Try ./setup --repo-help to print some examples which you can copy
into your cabal file.

I really appreciate this new repository location feature!
Thank you for adding it!
