Emacs.app was installed to:
#{prefix}
Command-line emacs can be used by setting up an alias:
alias emacs="#{prefix}/Emacs.app/Contents/MacOS/Emacs -nw"
To link the application to a normal Mac OS X location:
brew linkapps
or:
ln -s #{prefix}/Emacs.app /Applications

s += <<-EOS.undent
Because the official bazaar repository might be slow, we include an option for
pulling HEAD from an unofficial Git mirror:
brew install emacs --HEAD --use-git-head
There is inevitably some lag between checkins made to the official Emacs bazaar
repository and their appearance on the Savannah mirror. See
http://git.savannah.gnu.org/cgit/emacs.git for the mirror's status. The Emacs
devs do not provide support for the git mirror, and they might reject bug
reports filed with git version information. Use it at your own risk.
