+"""Generate Python documentation in HTML or text for interactive use.
+
+In the Python interpreter, do "from pydoc import help" to provide online
+help. Calling help(thing) on a Python object documents the object.
+
+Or, at the shell command line outside of Python:
+
+Run "pydoc <name>" to show documentation on something. <name> may be
+the name of a function, module, package, or a dotted reference to a
+class or function within a module or module in a package. If the
+argument contains a path segment delimiter (e.g. slash on Unix,
+backslash on Windows) it is treated as the path to a Python source file.
+
+Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines
+of all available modules.
+
+Run "pydoc -p <port>" to start an HTTP server on a given port on the
+local machine to generate documentation web pages.
+
+For platforms without a command line, "pydoc -g" starts the HTTP server
+and also pops up a little window for controlling it.
+
+Run "pydoc -w <name>" to write out the HTML documentation for a module
+to a file named "<name>.html".
+
+Module docs for core modules are assumed to be in
+
+ http://docs.python.org/library/
+
+This can be overridden by setting the PYTHONDOCS environment variable
+to a different URL or to a local directory containing the Library
+Reference Manual pages.
