script to print user schema

Does anyone have a sql script to produce a a copy of a users schema from the data dictionary? I have found a number of scripts to print out the describtions of the objects. (actually the one from the FAQ is about the best) But what I really want is a routine that produces an output file that can be run as a .sql.

ie) If I want to make a copy of a test database and use that output

    to create the userid in a production database.

Yes I can just use exp w/o the export rows option but I want to be able to check this resulting script into SCCS.
