#
# This module can either be compiled to produce an 'ni488' module that uses
# the National Instruments GPIB libraries, or to produce a 'linux_gpib'
# module that uses the Linux GPIB package that can be downloaded from
# http://linux-gpib.sourceforge.net/.  You cannot simultaneously build
# it for both.
#
# The National Instruments GPIB drivers are cross platform, but they have
# only been tested with MX under Linux.
