+=== SUMMARY ===
+
+The Signup Status Limit submodule allows you to limit the number of
+signups for each status on any given node.  On each node, you can
+select if you want to use a global limit across all status values, or
+to use per-status limits.
+
+
+=== DETAILS ===
+
+// TODO
+
+
+=== UPGRADING FROM DRUPAL 5 ===
+
+// TODO
+
+
+=== SUPPORT ===
+
+Bug reports, feature requests and support questions should use the
+"Signup status limit" component in the Signup status issue queue on
+drupal.org:
+
+http://drupal.org/project/issues/signup_status
+
+
+=== CREDITS ===
+
+In Drupal 5, some of this functionality existed directly inside the
+signup_status module, which was written by Jeffery Beeman
+(http://drupal.org/user/16734 -- "jrbeeman").
+
+The Drupal 6 version was a complete rewrite by Derek Wright
+(http://drupal.org/user/46549 -- "dww").
