+    This script enables per-page and per-group customizations in the
+    local/ subdirectory (or whatever directory is given by $LocalDir).  
+    For example, to create customizations for the 'Demo' group, place 
+    them in a file called local/Demo.php.  To customize a single page, 
+    use the full page name (e.g., local/Demo.MyPage.php).  
+    Per-page/per-group customizations can be handled at any time by adding
+	include_once("scripts/pgcust.php");
+    to config.php.  It is automatically included by scripts/stdconfig.php
+    unless $EnablePGCust is set to zero in config.php.
+
+    A page's customization is loaded first, followed by any group
+    customization.  If no page or group customizations are loaded,
+    then 'local/default.php' is loaded.  
+
+    A per-page configuration file can prevent its group's config from 
+    loading by setting $EnablePGCust=0;.  A per-page configuration file 
+    can force group customizations to be loaded first by using include_once
+    on the group customization file.
