  29  <ul><li>To return a list of links, one per line :<br>
  30     {links}</li>
  31     <li>To return a list, seperated by a # <br>
  32       {links sep=#}</li>
  33     <li>To return a list for the category humor <br>
  34       {links cat=humor}</li>
  35     <li>To return a list without the category stores <br>
  36       {links notcat=stores}</li>
  37     <li>To limit the number of links returned <br>
  38       {links num=5}</li>
  39     <li>The default behavior is to return the list in <br>
  40      or as set in the admin panel. This <br>
  41       can be changed with one of the following key words <br>
  42      <br>
  43       {links ord=nicename} <br>
  44       {links ord=category}</li>
  45     <li>To return a list in descending order <br>
  46       {links desc=TRUE}</li>
  47     <li>cat and notcat are mutually exclusive and cannot <br>
  48       be used together. They can both be used with sep, <br>
  49       ord, num and desc which can all be used together. <br>
  50       Category names and ord key words are case sensative.</li>
