27  A user-defined wrapper around string objects

29  This class is "borrowed" from the Python 2.2 UserString and modified 
30  slightly for use with SCons.  It is *NOT* guaranteed to be fully compliant 
31  with the standard UserString class from all later versions of Python. 
32  In particular, it does not necessarily contain all of the methods found 
33  in later versions.
