    Usage Details and Discussion
    This is an analogous tool to  icclu , but
    applying to MPP profile, rather
    than ICC profiles. Because MPP
    profiles can also contain a spectral description of device behavior,
    there are extra options in mpplu to describe how to convert spectral
    values into CIE tristimulus values.
    Some additional functionality is included in mpplu, analogous to  iccgamut, allowing gamut files and
    images to be generated from MPP profiles.
    
    The -v flag causes extra information about the profile to be
    printed.
    
    The -f flag is experimental, and should be ignored.
    
    Normally L*a*b* is displayed, but this can be changed using the the
    -p flag and XYZ, Yxy, or spectral values to be be displayed.
    
    If an illuminant, observer or Fluorescent Whitening Agent
    compensation is selected, then the CIE tristimulus values will be
    computed from the spectral information in the MPP profile (if
    present).
    
    The -l flag overrides any default ink limit (Total Area
    Coverage) recorded in the profile. The ink limit has an effect on
    the results of a gamut generated from the profile.
    
    The -i flag allows specifying a standard or custom
    illumination spectrum, applied to reflective spectral profile data
    to compute CIE tristimulus values. A, D50, D65,
    F5, F8, F10 are a selection of standard
    illuminant spectrums, with D50 being the default. If a
    filename is specified instead, it will be assumed to be an Argyll
    specific .sp spectrum file.
    
     The -o flag allows specifying a tristimulus
    observer, and is used to compute PCS (Profile Connection Space)
    tristimulus values. The following choices are available:
      1931_2 selects the standard CIE 1931 2 degree
    observer. The default.
      1964_10 selects the standard CIE 1964 10 degree
    observer.
      2012_2 selects the proposed CIE 2012 2 degree observer
      2012_10 selects the proposed CIE 2012 10 degree
    observer
      1955_2 selects the Stiles and Birch 1955 2 degree
    observer
      1978_2 selects the Judd and Voss 1978 2 degree
    observer
      shaw selects the Shaw and Fairchild 1997 2 degree
    observer
      file.cmf selects an observer specified by the
    given .cmf file.
    
    The -u flag enables Fluorescent Whitening Agent
    compensation, which compensates for the effect a different
    illuminant will have, on any Fluorescent Whitening Agent present in
    the reflective media.
    
    The -g flag causes mpplu to simply generate a gamut surface
    description from the profile, creating a .gam file with the same base
    name as the given profile.
    
    The -w flag causes the gamut surface to be generated in X3DOM format as well as .gam format.
    
    The -n flag suppresses the X3DOM
        axes.
        
        The -a n parameter sets a
        transparency level in the X3DOM surface.
    
    The -d parameter controls the level of detail displayed in
    the gamut surface. The parameter roughly corresponds to a deltaE
    value, so smaller values give greater detail. The default value is
    around 10, and is a good place to start. Small values may take a lot
    of time to generate, and will produce big files.
    
    The -t parameter invokes special MPP test and diagnostic
    output.
