/** This plots a poster or chart of various airfoils.

    All of the airfoils can be downloaded from:
    https://m-selig.ae.illinois.edu/ads/archives/coord_seligFmt.zip

    Usage:
       frink airfoilPoster.frink [filenames]

    This program is most easily run from the directory where the airfoils are
    extracted.  If no filenames are specified, this will render all .dat files
    in the current directory:

       frink airfoilPoster.frink

    If airfoil filenames are specified, this will render the specified airfoils
    which can be in a different directory.  Most generally, the command-line
    below will render the airfoils n*.dat.  MAKE SURE TO ADJUST ALL PATHS TO
    MATCH YOUR SYSTEM!
