38   * Adds the site descriptor (<code>site.xml</code>) to the list of files to be installed/deployed.<br/>
39   * For Maven-2.x this is enabled by default only when the project has <code>pom</code> packaging since it will be used by modules inheriting,
40   * but this can be enabled for other projects packaging if needed.<br/>
41   * This default execution has been removed from the built-in lifecycle of Maven 3.x for <code>pom</code>-projects.
42   * Users that actually use those projects to provide a common site descriptor for sub modules will need to explicitly define this goal execution to restore the intended behavior.
