 # ### Load and Run an Existing MODFLOW-2005 Model
 # A model called the "Freyberg Model" is located in the modelpth folder.  In the following code block, we load that model, then change into a new workspace (modelpth) where we recreate and run the model.  For this to work properly, the MODFLOW-2005 executable (mf2005) must be in the path.  We verify that it worked correctly by checking for the presence of freyberg.hds and freyberg.cbc.
