brew install scarce/axel/axelAxel is agent orchestration, designed for Rex. Every commit on
main of scarce/axel that passes CI is released,
and its release workflow moves Formula/axel.rb here, so brew upgrade always
brings you the newest build.
Use the full name scarce/axel/axel: Homebrew core has an unrelated axel.
Looking for Sonata? It moved to scarce/homebrew-taps:
brew install --cask scarce/taps/sonata (existing installs migrate on their own).
