+# this include file provides support for i18n
+#
+
+# usage:
+#   use the _() function for returning translated strings of
+#   text.  The string can contain escape codes %h for HTML
+#   and %s for regular text.
+#
+# supporting scripts:
+#   there is a supporting script, web/utils/genpopo, that will
+#   parse the PHP files and create PHP include files that contain
+#   a mapping for each translated language.  The include files
+#   have the form,
+#
+#     $_t["en"]["My cat is large."] = "My cat is large.";
+#     $_t["es"]["My cat is large."] = "Mi gato esta grande.";
+#
+# examples:
+#   print _("%s has %s apples.", array("Bill", "5"));
+#   print _("This is a %h%s%h problem!", array("<b>","major","</b>"));
+

+	if (!$LANG) {

+	$translated = $_t[$lang][$tag];
