<><> opam-depext.1.2.3 installed successfully <><><><><><><><><><><><><><><><><>
=> opam-depext is unnecessary when used with opam >= 2.1. Please use opam install directly instead

<><> ocaml-compiler.5.5.0~alpha1 installed successfully <><><><><><><><><><><><>
=> This switch had to be compiled from sources, but future switches with the 🐌

# To update the current shell environment, run: eval $(opam env)
