# A make command with no arguments will build the source disc variant with
# encrypted binaries, checksums enabled, the standard commander and crc32
# verification of the game binaries
#
# Optional arguments for the make command are:
#
#   variant=<release>   Build the specified variant:
#
#                         source-disc (default)
#                         text-sources
#                         sth
#
#   disc=no             Build a version to load from cassette rather than disc
#
#   protect=no          Disable block-level tape protection code (disc=no only)
#
#   commander=max       Start with a maxed-out commander
#
#   encrypt=no          Disable encryption and checksum routines
#
#   verify=no           Disable crc32 verification of the game binaries
#
# So, for example:
#
#   make variant=text-sources commander=max encrypt=no verify=no
#
# will build an unencrypted text sources variant with a maxed-out commander
# 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
#   1 = BBC Micro cassette
#
# _VARIANT
#   1 = Source disc
#   2 = Text sources
#   3 = Stairway to Hell (default)
#
# _MAX_COMMANDER
#   TRUE  = Maxed-out commander
#   FALSE = Standard commander
#
# _REMOVE_CHECKSUMS
#   TRUE  = Disable checksum routines
#   FALSE = Enable checksum routines
#
# _MATCH_ORIGINAL_BINARIES
#   TRUE  = Match binaries to released version (i.e. fill workspaces with noise)
#   FALSE = Zero-fill workspaces
#
# _DISC
#   TRUE  = Build for loading from disc
#   FALSE = Build for loading from cassette
#
# _PROT
#   TRUE  = Apply block-level tape protection
#   FALSE = Do not apply block-level tape protection
#
# The encrypt and verify arguments are passed to the elite-checksum.py and
# crc32.py scripts, rather than BeebAsm
