This scrapes GitHub's dep graph page to find dependents of a repo, and writes it to a file for processing.
This is useful because GitHub's API doesn't currently support querying dependents, and the page in the UI is not sorted.
pkg.go.dev
also shows dependents per-Go-package, including non-GitHub repos, but it's not sorted in any useful way to discover "popular" dependents.
Lines in the output are [repo] [stars] [forks]
It's incomplete and could probably be improved, but it scratches my itch. Feel free to fork it and do what you want.
