def caveats
unless use_default_names?; <<-EOS
All commands have been installed with the prefix 'g'. In order to use these
commands by default you can put some aliases in your bashrc. You can
accomplish this like so:
brew install coreutils --aliases >> ~/.bashrc
Please note the manpages are still referenced with the g-prefix.
