+
+    This function takes a notebook filename and returns the notebook
+    format (json/py) and the notebook name. This logic can be
+    summarized as follows:
+
+    * notebook.ipynb -> (notebook.ipynb, notebook, json)
+    * notebook.json  -> (notebook.json, notebook, json)
+    * notebook.py    -> (notebook.py, notebook, py)
+    * notebook       -> (notebook.ipynb, notebook, json)
+
+    Parameters
+    ----------
+    fname : unicode
+        The notebook filename. The filename can use a specific filename
+        extention (.ipynb, .json, .py) or none, in which case .ipynb will
+        be assumed.
+
+    Returns
+    -------
+    (fname, name, format) : (unicode, unicode, unicode)
+        The filename, notebook name and format.
