title: PHP_CodeSniffer rules documentation
body: <p>Where is it possible to find documentation on <a href="http://pear.php.net/package/PHP_CodeSniffer" rel="noreferrer">PHP_CodeSniffer</a> rules available? Seems to me like the rules exist, but nobody knows the list of them and their properties. I faced the essential problem, I want to customize a standard and force curly brace start on the same line after statement divided by one space and cannot see any way to do it. And this is only one issue, but I have many others.
  Thank you.</p>
