+
+==> libtool
+In order to prevent conflicts with Apple's own libtool we have prepended a "g"
+so, you have instead: glibtool and glibtoolize.
+==> lua
+You may also want luarocks:
+  brew install luarocks
+==> mariadb
+A "/etc/my.cnf" from another install may interfere with a Homebrew-built
+server starting up correctly.
+
+MySQL is configured to only allow connections from localhost by default
+
+To connect:
+    mysql -uroot
+
+To have launchd start mariadb now and restart at login:
+  brew services start mariadb
+Or, if you don't want/need a background service you can just run:
+  mysql.server start
+==> mono
+To use the assemblies from other formulae you need to set:
+  export MONO_GAC_PREFIX="/usr/local"
+```

+
+
+### Environnement:
+
+- `HOMEBREW_AUTO_UPDATE_SECS`: If set, Homebrew will only check for autoupdates once per this seconds interval.
+
+  *Default:* `300`.
+
+- `HOMEBREW_GITHUB_API_TOKEN`: A personal access token for the GitHub API, used by Homebrew for features such as `brew search`. You can create one at https://github.com/settings/tokens. If set, GitHub will allow you a greater number of API requests. For more information, see: https://developer.github.com/v3/#rate-limiting
+
+  *Note:* Homebrew doesn’t require permissions for any of the scopes.
+
+- `HOMEBREW_NO_AUTO_UPDATE`: If set, Homebrew will not auto-update before running `brew install`, `brew upgrade` or `brew tap`.
+
+- `HOMEBREW_VERBOSE`: If set, Homebrew always assumes `--verbose` when running commands.
+
+
