A user-defined wrapper around string objects
|
|
|
|
This class is "borrowed" from the Python 2.2 UserString and modified
|
|
slightly for use with SCons. It is *NOT* guaranteed to be fully compliant
|
|
with the standard UserString class from all later versions of Python.
|
|
In particular, it does not necessarily contain all of the methods found
|
|
in later versions.
