* messy_ncregrid_tools_e5.f90: bug fix in SUBROUTINE
  RGTOOL_E5_READ_NCFILE (allocation of global field
  (not scattered))

-----------------------------------------------------
changes from v1.1b to v1.2b
-----------------------------------------------------
* SUBROUTINE RGTEVENT_INIT_NML(messy_ncregrid_tools_e5.f90):
  active RG_TRIG(.) in RGTEVENTS-namelists must not longer have
  successive numbers
* SUBROUTINE RGTEVENT_READ (messy_ncregrid_tools_e5.f90):
  new optional INTENT(OUT) parameter for event status
* mo_mz_regrid* renamed to messy_ncregrid*
  since ncregrid is now essential part of the
  Modular Earth Submodel System (MESSy)
  (http://www.messy-interface.org)
* mo_mz_regrid_tools_e5.f90 (SUBROUTINE TRACER_INIT):
  initialization of LAGRANGIAN tracers
* mo_mz_regrid_tools_e5.f90 (SUBROUTINE TRACER_INIT):
  regridding of tracers is skipped, if all tracers
  have been initialized from rerun-files

-----------------------------------------------------
changes from v1.0b to v1.1b
-----------------------------------------------------
* mo_mz_regrid_interface_echam5.f90:
  adaption to echam5.1.07: gmu -> gl_gmu
* mo_mz_regrid_tools_e5.f90:
  - changes for vectorization: nglon -> nproma
  - factor (1. - eps) in tracer initialisation at t-1
    after restart (SUBROUTINE TRACER_INIT)
  - changes for MPI-parallelisation:
    - 3D(4D) fields are now distributed by scatter_gp,
      if regridding was performed in all dimensions
      (otherwise the complete field is distributed via p_bcast)
    - The 2D surface pressure (ps) is now distributed by scatter_gp,
      if regridding was performed along the horizontal dimensions
      (otherwise the complete field is distributed via p_bcast)
    (SUBROUTINES RGTOOL_E5_READ_NCVAR and RGTOOL_E5_READ_NCFILE)
* mo_mz_regrid_tools_e5.f90:
  'CALL finish' moved to within I/O-processor blocks

-----------------------------------------------------
changes from v0.9a1.10 to v1.0b
-----------------------------------------------------
* minor bug fixes + better f90/f95 standard conformance
* New SUBROUTINE RGTEVENT_READ (mo_mz_regrid_tools_e5.f90):
  RGTEVENT-status testing and NCREGRID data input
  via RGTOOL_E5_READ_NCVAR or RGTOOL_E5_READ_NCFILE
* Two new PUBLIC INTEGER PARAMETERS:
  RGREAD_NCVAR and RGREAD_NCFILE to control RGTEVENT_READ
* 'vname' in SUBROUTINE RGTOOL_E5_READ_NCFILE is renamed  
  to 'vars'.
* The maximum number of RGTEVENTS per module is now 500 instead of
  100 (PARAMETER NMAXRGTE in mo_mz_regrid_tools_e5.f90)
* New parameter (LOGICAL, OPTIONAL, INTENT(IN)) in 
  SUBROUTINE RGTEVENT_STATUS (mo_mz_regrid_tools_e5.f90):
  lstop = .true.  -> STOP echam5 in case the event is not found
  lstop = .false. -> output WARNING message

-----------------------------------------------------
changes from v0.9a1.09 to v0.9a1.10 (15 November 2002)
-----------------------------------------------------
* New module in examples/tools (mo_mz_regrid_tools_e5.f90)
  with ECHAM-5 specific routines for coupling NCREGRID
  to ECHAM-5:
   RGTEVENT              ! RG-TRIGGER EVENT STRUCTURE
   RGTOOL_E5_READ_NCVAR  ! READ ONE FIELD WITH NCREGRID
   RGTOOL_E5_READ_NCFILE ! READ ONE FIELD WITH NCREGRID
   RGTEVENT_INIT_NML     ! READ RGT-EVENT INFORMATION FROM NAMELIST
   RGTEVENT_STATUS       ! GET STATUS OF NAMED/INDEXED EVENT AND
                         ! UPDATE RESTART FILE
   TRACER_INIT           ! INITIALIZE TRACER
