    General notice:
    This code is part of a boot-monitor package developed as a generic base
    platform for embedded system designs.  As such, it is likely to be
    distributed to various projects beyond the control of the original
    author.  Please notify the author of any enhancements made or bugs found
    so that all may benefit from the changes.  In addition, notification back
    to the author will allow the new user to pick up changes that may have
    been made by other users after this version of the code was distributed.

/* 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.
