Automatically fill in author, author URL, license, and so on
To reduce duplication across projects, I should just have the template fill in the default author (aka me), also the author URL, and the license, and the vcs, and also deduce the license from the git URL. By default; users can just override that, but since this template is probably not going to be used on other websites there's no need to assume that.
Deleting a branch is permanent. It CANNOT be undone. Continue?
