+    Because ROOT depends on several installation-dependent
+    environment variables to function properly, you should
+    add the following commands to your shell initialization
+    script (.bashrc/.profile/etc.), or call them directly
+    before using ROOT.
+
+    For csh/tcsh users:
+      source `brew --prefix root`/bin/thisroot.csh
+    For bash/zsh users:
+      . $(brew --prefix root)/bin/thisroot.sh
