"""ZODB undo support for Zope.
This package is used to support the Prefix object that Zope uses for
undo. It is a separate package only to aid configuration management.
This package is included in Zope and ZODB3, so that ZODB3 is suitable
for running a ZEO server that handles Zope undo.

"""A Prefix() is equal to any string it as a prefix of.
This class can be compared to a string (or arbitrary sequence).
The comparison will return True if the prefix value is a prefix of
the string being compared.
Two prefixes can not be compared.
