  19  <p>This is a basic GreyMatter to WordPress import script.</p>
  20  <p>What it does:</p>
  21  <ul>
  22  <li>Parses gm-authors.cgi to import (new) authors. Everyone is imported at level 1.</li>
  23  <li>Parses the entries cgi files to import posts, comments, and karma on posts (although karma is not used on WordPress yet).<br />If authors are found not to be in gm-authors.cgi, imports them at level 0.</li>
  24  <li>Detects duplicate entries or comments. If you don't import everything the first time, or this import should fail in the middle, duplicate entries will not be made when you try again.</li>
  25  </ul>
  26  <p>What it does not:</p>
  27  <ul>
  28  <li>Parse gm-counter.cgi, gm-banlist.cgi, gm-cplog.cgi (you can make a CP log hack if you really feel like it, but I question the need of a CP log).</li>
  29  <li>Import gm-templates.</li>
  30  <li>Doesn't keep entries on top.</li>
  31  </ul>
