+Description of files in this directory
+======================================
+
+$Header$
+
+This file contains (typically) one file for each model, containing
+a Fortran-callable subroutine
+ subroutine Exact__model_name_coords(
+ $ x, y, z, t,
+ $ gdtt, gdtx, gdty, gdtz,
+ $ gdxx, gdyy, gdzz, gdxy, gdyz, gdzx,
+ $ gutt, gutx, guty, gutz,
+ $ guxx, guyy, guzz, guxy, guyz, guzx)
+to compute the 4-metric $g_{ab}$ and inverse 4-metric $g^{ab}$.
+
+FIXME: Wouldn't it be cleaner to just compute $g_{ab}$,
+ and use a 4x4 matrix inversion to get the other one?
