# While this is a good example script to teach about introspection,
# in real life it has been superceded by PyDoc, which is part of the
# standard library in Python 2.1 and later.
#
# Your IDE may already import the "help" function from pydoc
# automatically on startup; if not, do this:
#
# >>> from pydoc import help
#
# The help function in this module takes the object itself to get
# help on, but PyDoc can also take a string, like this:
#
# >>> help("string") # gets help on the string module
# >>> help("apihelper.help") # gets help on the function below
# >>> help() # enters an interactive help mode
#
# PyDoc can also act as an HTTP server to dynamically produce
# HTML-formatted documentation of any module in your path.
# That's wicked cool. Read more about PyDoc here:
# http://www.onlamp.com/pub/a/python/2001/04/18/pydoc.html
