+=head1 DESCRIPTION
+
+This script will take a userid and search the Active Directory for the user and
+return an image file if the user has an image associated with his 
+thumbnailPhoto attribute.
+
+This can be configured into Perforce Swarn as documented:
+
+http://www.perforce.com/perforce/doc.current/manuals/swarm/admin.avatars.html
+
+One would use something like
+
+  // this block should be a peer of 'p4'
+  'avatars' => array(
+    'http_url'  => 'http://<server>/cgi-bin/getPicture.pl?userid={user}'
+    'https_url' => 'http://<server>/cgi-bin/getPicture.pl?userid={user}',
+  ),
