# The board and variant command line options can be used in a number of ways
# to specify the board and variant. The board can encode both pieces of
# information separated by underscores. Or the variant can be passed using
# the separate variant option. This function extracts the canonical board and
# variant information and provides it in the BOARD, VARIANT and BOARD_VARIANT
# variables.
