 This product provides a way to have consistent backups when running a
 multi-storage instance (only ZEO is supported at the moment).

 Here, T2 was able to commit entirely, but it must not be saved. This is
 because transactions are stored in ZODB in the order they are committed.
 So is T2 is in the backup, a part of T1 will also be, and backup will be

+USAGE
+=====
+
+Put product in Zope Products to activate Zope-side patches.

+PYTHONPATH issues
+-----------------
+
+To run server and scripts there is a need to set correct PYTHONPATH - at least
+to product directory and for some tools to Zope lib/python.

+=================
 
 TIDStorage fixes those issues by keeping track of transaction-to-tid relations
 for all (ZODB, via ZEO) storages involved in any transaction, and by tracking
