+# This parameter file sets up Misner initial data and finds the
+# apparent horizons in it with AHFinderDirect.
+#
+# This run shows the AHFinderDirect interpolator parameters you need
+# to set to run with PUGH::ghost_size = 2.
+#
+# Note that the grid is very high-resolution, but small (the outer
+# boundaries are very close in).  This isn't a problem for the purposes
+# of this test.  This run takes about 198 megabytes of memory, and
+# 36 cpu seconds on a 1.07GHz PIII laptop.
