# A make command with no arguments will build the Ian Bell Superior Software
# 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:
#
#                         ib-superior (default)
#                         ib-acornsoft
#
#   commander=max       Start with a maxed-out commander
#
#   verify=no           Disable crc32 verification of the game binaries
#
# So, for example:
#
#   make variant=ib-acornsoft commander=max verify=no
#
# will build the Ian Bell Acornsoft variant with a maxed-out commander and
# no crc32 verification
