    27  A user-defined wrapper around string objects
    28
    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.
