+Overview
+    Marshalling hotfix for ZTUtils
+
+Installation
+
+    To install the hotfix, unpack the tarball file into the
+    'Products' directory of your site's INSTANCE_HOME, and then restart
+    your Zope application server.
+    
+    E.g., if on your system, the Zope software is installed in
+    '/opt/lib/zope2.7', and your instance is in '/var/lib/zope'::
+
+      # cd /var/lib/zope/Products
+      # tar xzf /tmp/ZTUtils_hotfix.tar.gz
+      # ../bin/zopectl restart
+
+Removeal
+
+    To remove the hotfix, simply remove the product folder
+    and restart the application server.
+    
+    E.g., for the same setup::
+    
+      # cd /var/lib/zope/Products
+      # rm -r ZTUtils_hotfix
+      # ../bin/zopectl restart
