Brew formula (for macOS)

[yvele]

Looks like this from the official doc doesn't work anymore:

brew install --HEAD homebrew/head-only/gitstats

Error: homebrew/head-only was deprecated. This tap is now empty and all its contents were either deleted or migrated.

https://github.com/Homebrew/homebrew-head-only/blob/master/gitstats.rb leads to a 404 error

When I try brew install gitstats I get the following error:

Warning: No available formula with the name "gitstats". Did you mean gitslave?

Homebrew 4.2.2 macOS Montery v12.6

I also get the same error too, how do I fix this problem?
