-How to use the documentation
-----------------------------
 
-MOOSE documentation is split into Python documentation and builtin
-documentation. The functions and classes that are only part of the
-Python interface can be viewed via Python's builtin ``help``
-function::
+from __future__ import print_function
+from __future__ import absolute_import 
+    
 
->>> help(moose.connect)
+from contextlib import closing
+import warnings
+import platform
+import pydoc
+import os
+from io import StringIO
+from collections import defaultdict
 
-The documentation built into main C++ code of MOOSE can be accessed
-via the module function ``doc``::
+import moose
+from moose._moose import *
+import moose.SBML
 
->>> moose.doc('Neutral')
+# Wrapper to get moose version information.
+__version__ = moose._moose.__version__
+VERSION = moose._moose.VERSION
 
-To get documentation about a particular field::

-    Parameters
-    ----------
-    arg : str/class/melement/vec
-        A string specifying a moose class name and a field name
-        separated by a dot. e.g., 'Neutral.name'. Prepending `moose.`
-        is allowed. Thus moose.doc('moose.Neutral.name') is equivalent
-        to the above.
-        It can also be string specifying just a moose class name or a
-        moose class or a moose object (instance of melement or vec
-        or there subclasses). In that case, the builtin documentation
-        for the corresponding moose class is displayed.
-
-    paged: bool
-        Whether to display the docs via builtin pager or print and
-        exit. If not specified, it defaults to False and
-        moose.doc(xyz) will print help on xyz and return control to
