-# prompted variables are a list of variable names and a description
-# that will be presented to the user, or a list of variable dictionaries
-# with the following accepted keys / value types: 
-#    'name' / text
-#    'prompt' / text (optional)
-#    'private' / boolean (optional)
+# here's basic mode prompting.  Specify a hash of variable names and a prompt for
+# each.
