+    ppOpen-APPL/FVM ia a coupling library that enables weak
+    coupling on various simulation models, such as an
+    atmospheric model and an ocean model, a seismic model
+    and a structure model.  For getting very wide
+    applicability, ppohMATHMP is designed so as that it is
+    independent from grid structure.  Instead of grid
+    structure, ppOpen-APPL/FVM requires a data set
+    called 'mapping table'. Mapping table is composed of
+    a correspondence table of grid indexes between a send
+    model and a receive model and interpolation coefficients.
+    A subroutine for making a mapping table file is provided
+    by ppohMATHMP API.
+
+    Current version of ppohMATHMP is ver.1.0 which targets
+    scalar data exchange.  An exchange code of vector data
+    which requires rotation calculation is under
