-// Since it is not of use for general HyperRogue players,

-// How to use:
-
-// hyper -embed <start of filename> -- visualize a social network
-//   embedded into hyperbolic plane, see:
-//   https://bitbucket.org/HaiZhung/hyperbolic-embedder/overview
-//   (it uses the same format)
-
-// hyper -tess <parameter file> -- visualize a horocyclic tesselation,
+// This is the main file for such graph visualizations. It is used
+// by SAG, SOM, DHRG, and some other modules.
