A simple PHP script to generate the XML necessary for Sonar to detect the Drupal Coder module's sniffs. See: https://drupal.org/node/2082563

 * Generate rules for Drupal Coding Standards Sniffs.
 *
 * SonarQube requires manually-entered PHP CodeSniffer rules if you use anything
 * outside of the standard set of rules. In this case, there are a bunch of
 * Drupal-specific sniffs that we'd like to use.
 *
 * This file takes an array of sniff keys and generates the appropriate XML to
 * pasted into the sonar.phpCodesniffer.customRules.definition setting inside
 * Sonar's Configuration area.
 *
 * After pasting the generated XML, you need to restart the SonarQube server,
 * then enable all the rules you want to use in a quality profile.
 *
 * @see http://docs.codehaus.org/display/SONAR/PHP+Custom+Coding+Rules
 * @see http://docs.codehaus.org/display/SONAR/Quality+Profiles
