Faulty script on published page https://www.torproject.org/docs/tor-doc-osx.html.en
I tried the published link on the page that is attached: ruby -e "$(curl -fsSkL https://raw.github.com/Homebrew/homebrew/go/install)"
and got an error message and the following updated link.
The current correct script to download and install 'Homebrew' appearsto be: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You may wish to make the correction on the published information for the Tor Project.
