#  Discussion:
#
#    This is simply a list of the total system size,
#    and the files that describe the subsystems.
#
#    The first subsystem is a matrix A and right hand side B
#    whose residual norm || A * X - B || is to be minimized.
#
#    The second subsystem is a matrix C and right hand side D
#    which represent constraints, that is, it must be the
#    case that C * X = D exactly.
#
#    The third subsystem is a matrix E and right hand side H
#    which represent positivity constraints, that is, it must be the
#    case that E * X >= H.
#
#    The L-infinity solution is ( 4/3, -1/3, 2/3 ) with
#    objective function value 2/3.
