 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.
