/* Specify inclusion of subsystems within the monitor here.
   Subsystems are included/excluded by defining a few macros to 1/0.
   Following are the subsystem groupings based on commands and/or capability:

    INCLUDE_MEMCMDS:        dm, pm, cm, fm, sm, mt
    INCLUDE_PIO:            pio
    INCLUDE_EDIT:           edit
    INCLUDE_DEBUG:          argv, at, dr, go, pr, ss, vfy
    INCLUDE_DISASSEMBLER:   dis
    INCLUDE_UNPACK:         unpack and huffman file decompression
    INCLUDE_ETHERNET:       ether
    INCLUDE_TFS:            tfs
    INCLUDE_MALLOC:         malloc
    INCLUDE_SHELLVAR:       set and shell variables
    INCLUDE_XMODEM:         xmodem
    INCLUDE_UNZIP:          unzip and zlib file decompression
    INCLUDE_EE:             let (expression evaluator)
    INCLUDE_FLASH:          flash operations (required by TFS)
    INCLUDE_CRYPT:          unix-crypt instead of my own "cheap crypt"
                            (see common/crypt.c)
    INCLUDE_LINEEDIT:       vi-like line editor for command line interface
                            and edit.

   Note that these INCLUDE macros allow the monitor to be built in a 
   variety of configurations; some of which may put extreme limitations
   on the capability of the monitor.  For example, it is recommended that
   at least INCLUDE_ETHERNET or INCLUDE_XMODEM be defined otherwise
   there is no download capability in the monitor.  The primary function
   of these macros is to limit complexity during monitor installation on 
   a new system and to save flash space if a particular module is of no
   value.

   A starting point for building a monitor must include:
        SHELLVAR, MALLOC & XMODEM
