      Add the following to your .bashrc or equivalent:
        export GUILE_LOAD_PATH="#{HOMEBREW_PREFIX}/share/guile/site/3.0"
        export GUILE_LOAD_COMPILED_PATH="#{HOMEBREW_PREFIX}/lib/guile/3.0/site-ccache"
        export GUILE_SYSTEM_EXTENSIONS_PATH="#{HOMEBREW_PREFIX}/lib/guile/3.0/extensions"

      Then run the following to initialize msg:
        msg machine init
    EOS
  end

  test do
    system "/opt/homebrew/bin/msg"
  end
