-    Syntax:
-        :samp:`checkpoint("{filename}")`
-
-    Description:
-        saves the current state of the system in a portable file to 
-        allow one to take up where you left off -- possibly on another 
-        machine. Returning to this state is accomplished by running the 
-        program with the checkpoint file as the first argument. 
-        If the checkpoint file is inconsistent with the executable the 
-        program prints an error message and exits. 
-
-        At this time many portions of the computer state are left out of the 
-        checkpoint file, i.e. it is not as complete as a core dump. 
-        Some things that ARE included are: 
-        all interpreter symbols with definitions and values, 
-        all hoc instructions, 
-        all neuron state/parameters with mechanisms. 
-        Many aspects of the GUI are not included. 
-
-    .. warning::
-        There is not enough implementation at this time to make this 
-        facility useful. Use the :hoc:class:`SaveState` class instead.
