title: How can i get more info about a brew formula before installing?
body: <p>I know i can do something like </p>
  
  <pre><code>## brew info FORMULA_NAME
  brew info wgetpaste
  </code></pre>
  
  <h2>Output</h2>
  
  <pre><code>wgetpaste: stable 2.20
  http://wgetpaste.zlin.dk/
  Not installed
  https://github.com/mxcl/homebrew/commits/master/Library/Formula/wgetpaste.rb
  </code></pre>
  
  <p>Then i can follow the url to get some info about the formula before installing. Do we have any way to get this info in command line using brew?</p>
