# A make command with no arguments will build the PAL variant with
# the standard commander and crc32 verification of the game binaries
#
# Optional arguments for the make command are:
#
#   variant=<release>   Build the specified variant:
#
#                         pal (default)
#                         ntsc
#
#   commander=max       Start with a maxed-out commander
#
#   match=no            Do not attempt to match the original game binaries
#                       (i.e. omit workspace noise)
#
#   verify=no           Disable crc32 verification of the game binaries
#
# So, for example:
#
#   make variant=ntsc commander=max match=no verify=no
#
# will build an NTSC variant with a maxed-out commander, no workspace noise
# and no crc32 verification
#
# The following variables are written into elite-build-options.asm depending on
# the above arguments, so they can be passed to BeebAsm:
#
# _VERSION
#   7 = NES
#
# _VARIANT
#   1 = NTSC (default)
#   2 = PAL
#
# _MAX_COMMANDER
#   TRUE  = Maxed-out commander
#   FALSE = Standard commander
#
# _MATCH_ORIGINAL_BINARIES
#   TRUE  = Match binaries to released version (i.e. fill workspaces with noise)
#   FALSE = Zero-fill workspaces
#
# The verify argument is passed to the crc32.py script, rather than BeebAsm
