# GETARCH -- Determine or set the current platform architecture parameters.
#
# Usage: getarch
# getarch -set [<arch>] [opts]
#
# -mach print the architecture name [default]
# -current print the currently configured arch
# -nbits print number of bits in an int (32 or 64)
#
# -actual print actual architecture name regardless of VOCARCH
# -set <arch> manually reset the environment architecture
