To be more verbose:

/**
  * Base URL (optional).
  *
  * If you are experiencing issues with different site domains,
  * uncomment the Base URL statement below (remove the leading hash sign)
  * and fill in the URL to your Drupal installation.
  *
  * You might also want to force users to use a given domain.
  * See the .htaccess file for more information.

And:

   # If your site can be accessed both with and without the prefix www.
   # can use one of the following settings to force user to use only one
   #
   # If you want the site to be accessed WITH the www. only, adapt and
   # uncomment the following:
   # RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
   # RewriteRule .* http://www.example.com/ [L,R=301]
   #
   # If you want the site to be accessed only WITHOUT the www. prefix,
   # and uncomment the following:
   # RewriteCond %{HTTP_HOST} !^example\.com$ [NC]
   # RewriteRule .* http://example.com/ [L,R=301]
