/** 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!
/path/to/frink /path/to/airfoilPoster.frink /path/to/airfoils/n*.dat
