+* - comment code (Boss)
+* - replace remaining MDB magic constants with #defines (Hofer)
+* - support command line option to "disable_mdb" to run without
+*   connected MDB (instead of failing to launch); in this
+*   mode, print out what WOULD be done with MDB (Grothoff)
+* - in keyboard interaction, distinguish between
+*   payment pending and payment not pending, allow
+*   'c', only if pending (Grothoff)
+* - have new state for waiting for MDB to signal vend success/failure
+*   in keyboard interaction prompt for success y/n at that time (or c cancel) 
(Grothoff)
+* - add key strokes for "failure to vend" and "vend successful"
+*   (useful when faking MDB interaction), factor out function for
+    the respective operations! (Grothoff)
+* - implement refunds on failure to vend (TBD)
