Specifically, it can accept all the VCS tag specs that head could,
making it more useful for defining stable versions that come from
VCS instead of tarballs.
A new "SoftwareSpecification" class was added to implement this.
This new class holds a "spec" for downloading a software package.
It combines the url (or head url) with the "specs" [1] that head has
been able to take.
This allows both the stable (url) and unstable (head) specification
for a software package to co-exist without stomping on each others
"specs".
[1] "specs" contain instructions on which branch/tag/revision/etc. to use
from the source repository URL.

Features and usage are summarized on the homepage.
Quick Install to /usr/local
This script will prompt for confirmation before it does anything:
ruby -e "$(curl -fsS http://gist.github.com/raw/323731/install_homebrew.rb)"
Afterwards, install Xcode.
Umm… I thought I could install it anywhere?
Indeed, you can. Refer to our complete installation instructions.
Dude! Just give me a one-liner!
Okay then, but please note this installs Homebrew as root and we recommend against that.
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1
