+ """Convenience function for looking up server-side objects
+ through PERF directories and for multiple uses. The object
+ name can be given as "MODULE.OBJECT", which will look up the
+ named OBJECT in the named MODULE, and can be followed by any
+ number of slash-separated names, which will assume that the
+ object to the left of the slash is a PERF directory, and will
+ return the object in that directory by the name to the right
+ of the slash. For instance, find("pdm.perf.sysres/cputime")
+ will return the built-in attribute for reading the CPU time
+ used by the server process.
+
+ The proxy objects returned by this function are cached and the
+ same object is returned the next time the same name is
+ requested, which means that they are kept live until the
+ client connection is closed.
