I have a simple descriptor to create a cached property as shown below.

The problem is that when I use the help() function on them, I don't
get the doc string from the function that is being wrapped.

What do I need to do to get the doc string of the wrapped function to
apper when using help()?
take a look at
http://pypi.python.org/pypi/decorator
and possibly
http://docs.python.org/library/functools.html#functools.update_wrapper
That doesn't help. The descriptor *does* have its docstring copied from
the function. But pydoc (the module behind the help system) doesn't handle
the case - "normal" properties are handled specially, but a generic
descriptor like that is not understood.
(and it's not so easy to fix - pydoc does a lot of things, all intermixed:
it tries to discover all
methods and attributes, determine which are relevant, extract
documentation from them, organize and clasify such documentation, generate
HTML files/text files/present it to the user/run a webserver/invoke the
pager... Too much for my taste, but I disgress...)
