The <a href=":pathauto_pattern">"Patterns"</a> page is used to configure automatic path aliasing.  New patterns are created here using the <a href=":add_form">Add Pathauto pattern</a> button which presents a form to simplify pattern creation thru the use of <a href="token">available tokens</a>. The patterns page provides a list of all patterns on the site and allows you to edit and reorder them. An alias is generated for the first pattern that applies.
