define MSP_HELP

 MSP extras:

   debug    : compile with minimal optimization and debug symbols
   debugopt : compile with debug symbols
   xnp      : compile for network programming

 Programmer options:

   bsl,auto      : (default) use BSL programmer on the first mote found
   bsl,<port>    : use BSL programmer on <port> serial port
   bsl,ref,<ref> : use BSL programmer on the mote with reference <ref>

   The dev or host parameter for the programmer option need not be specified,
   in which case it is expected to be defined as in an environment variable of
   the same name in all caps (such as BSL).
