+C This program provides an example of how to call the C version of AMD
+C from a Fortran program.  It is HIGHLY non-portable.
+
+C The amd_order routine returns PERM (1) < 0 if an error occurs.
+C (-1: out of memory, -2: invalid matrix)
+
+C Note that the input matrix is 0-based.  From Fortran, column j of the
+C matrix is in AI (AP (I)+1 ... AP (I+1)).  The row indices in this
+C set are in the range 0 to N-1.  To demonstrate this translation,
+C the input matrix is printed in 1-based form.  This program uses
+C the same 5-by-5 test matrix as amd_simple.c.
