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
