[1]	20	! Revision 1.2 2004/04/30 13:12:17 raasch
	21	! Switched from mpi_alltoallv to the simpler mpi_alltoall,
	22	! all former transpose-routine files collected in this file, enlarged
	23	! transposition arrays introduced
	24	!
	25	! Revision 1.1 2004/04/30 13:08:16 raasch
	26	! Initial revision (collection of former routines transpose_xy, transpose_xz,
	27	! transpose_yx, transpose_yz, transpose_zx, transpose_zy)
