# IRAFARCH -- Determine or set the current platform architecture parameters.
#
# Usage: irafarch
# irafarch -set [<arch>] [opts]
# irafarch [ -hsi | -nbits | -pipe | -tapecap | -tape ]
#
# -mach print the iraf architecture name [default]
# -hsi print the HSI arch
# -nbits print number of bits in an int (32 or 64)
# -pipe does platform support display fifo pipes?
# -tapecap does platform require tapecap changes?
# -tape does platform support tape drives?
# -shlib does platform support iraf shared libs?
#
# -actual print actual architecture name regardless of IRAFARCH
# -set <arch> manually reset the iraf environment architecture
