	  but is treated as potentially having missing (often
	  by having the valid_* attributes of NetCDF.)

          'legend_size') By defualt it is shown in the right margin of vpt.
	  'legend' is a String to show, or true to show the name of the
	  current GPhys object.

	  >>  not to take 
	  >>    na_other = self.data.val.fill(other)
          >>  which is inefficitent. But this would require a
  	  by re-activating l.636 (be removing comment-out chars).
	  Plus, a minor debug of an enbug on Jun 16.

	  * not to take 
	      na_other = self.data.val.fill(other)
            which is inefficitent. But this would require a
	    future new version of NArrayMiss (later than 1.1.1)
	  * set nil to units of a Numric/NArray for
	    correct units handling bor both add/sub and mlt/div (see below).
	* varray.rb : 
	  * Binary_operators_Uconv (+,-,add!,sbt!) : to use other's units

	* gphys_netcdf_io.rb: NetCDF_IO::open : improved handling of
	  files without coordinate variables. (add "_#{dim}" to

Mon Jun  6  2005   T Horinouchi
	* gphys_io_common.rb: IO_Common::each_along_dims_write : changed to
	  use the new grid obtained with *_IO::write_grid

          Date: Wed, 27 Apr 2005 11:00:40 +0900)]
	* gphys_netcdf_io.rb: GPhys::NetCDF_IO::write_grid : changed
	  to return a Grid object, in which all VArrays in the original
	  grid are replaced with the new ones in the file (the return

	* grads_gridded.rb: GrADSVar#initialize: added attribute 
	  'missing_value', which is 'undef' in GrADS_Gridded.
	* grads_gridded.rb: GrADS_Gridded#parse_ctl: change in the
	  relative path intepretation: to deal with path without
	  '^' at the beginning (BEFORE: '^hoge' -> absolute path,
	  'hoge' -> remained relative; AFTER: both -> absolute path.
	  So you don't need to be at the data directory anymore.)
Tue May 24  2005   T Horinouchi
	* grads_gridded.rb: GrADS_Gridded#get_dim: to use float for
 	  spacial dimensions as well as time.
	  GrADSVar#vartype: to return 'float' for coordinate variables.

	* gdir.rb: sort gdirs and texts in list_*; plus, a very minor change
	* gdir_connect_ftp-like.rb: start_dcl: to call 
	  DCL.swpset('lwait',false) (if you don't like it, you don't need to
	  use start_dcl.)
Wed May 11  2005   T Horinouchi
	* Merged gphys-remote-0.4 in gphys:
	  * commands bin/gdir_server and bin/gdir_client
	    (the former was renamed from gdir_server.rb in gphys-remote).
	  * irb start-up file lib/numru/gdir_connect_ftp-like.rb
            (renamed from gphys_connect_ftp-like.rb in gphys-remote).
Tue May 10  2005   T Horinouchi
	* ggraph.rb: GGraph's visualization methods are changed to call
	  DCL.gropn(1) if gropn/sgopn has not been called
	  (by introducing GGraph::gropn_1_if_not_yet).
	* gdir.rb: Added GDir.pwd, GDir#each_dir, GDir#each_data.
          show, show_v are reorganized and renamed to list_all,
	  list_all_v, which returns the result as strings.
	  ls / ls_l now prints their results.
Mon May  9  2005   T Horinouchi
	* subsetmapping.rb: SubsetMapping1D.new: support reversed range.
	* varray.rb: VArray#val: interpret Hash slicers for NArray/NArrayMiss
	* ggraph.rb: 
	  GGraph::map: added option 'fill'.

	  the anti-clockwise coordinate to get around a bug in UMFMAP in
	  DCL 5.3
Fri May  6  2005   T Horinouchi < T Koshiro
	* ggraph.rb: GGraph::map added options "dgridmj" and "dgridmn"
Wed Apr 27  2005   T Horinouchi
	* ggraph.rb: separated annotate_at from annotate
Fri Apr 15  2005   T Horinouchi
	* ggraph.rb: Further modification for map projection:
	  The strategy of the previous edition was not good.
	  If map is to be drawn, 'itr' should be 10 and axes should be drawn
	  afterwards. Eliminated the new "map" and introduced "map_axes".
Fri Apr 15  2005   T Horinouchi
	* lib/numru/gdir.rb: added GDir#open_all_data. Renamed ls_v ->
	  ls_l, which I originally meant. Supported path in show, show_v.
	  Support the path argument in show and show_v
	* gphys_io.rb: corrrected a spell miss of method name in documentation
	* ggraph.rb: Revision regarding map projection:
	  * GGraph::fig: Option changed from map_lat_range -> map_window
	    (the latter includes log-lat range, and the former is eliminated).
	    Added new option 'map_fit', which is for itr=10 and 11.
	    Changed the default behavior for itr=10 (cylindrical) to fit
            the map to the data window (equiv to 'map_fit'=>true). 
	    Concequently, the default window for itr=10 is now the same as 
	    with itr=1.
	  * GGraph::tone & GGraph::contour: added option 'map_fit', 
	    which draws map etc by switching temporarilly to itr=10 and
	    calling GGraph::map.
	* sample/map_projection.rb: Revised according to the change 
	  of ggraph.rb. New samples were added regarding the 'map_fit'
	  option of fig and the 'map' option of tone/contour.
	* doc/: updated
Wed Apr 13  2005   T Horinouchi
	* lib/numru/gdir.rb: Imported (moved) from gphys-remote-0.3. It will be
	  maintained here.

Mon Apr  4  2005   S Nishizawa
	* grib.rb, grib_params.rb: change not to set attribute of "units" when variables have no unit.
Fri Apr  1  2005   T Horinouchi
        * gphys_netcdf_io.rb: added a test regarging packed data.
	* Revised netcdf convension handling. This improves attribute 
	  handling of the user's guide convention (the default one)
	  regarding data missing etc.
	  * attributenetcdf.rb: AttributeNetCDF#initialize to extend
	    Attribute_Mixin whose default is defined in netcdf_convention.rb
	  * netcdf_convention.rb: created module Attribute_Mixin
	    in NetCDF_Convention_Users_Guide. Moved contents of 
	    VArray_Mixin to Attribute_NetCDF, which is to move
	    attribute editor on copying (deep-cloning) from VArrayNetCDF
	    to AttributeNetCDF (which is used in VArrayNetCDF).
	* grads_gridded.rb: minor revision of documentation.
	  allowed modes: "r" & "w+" --> "r" & "w" (read only / write only).
	* doc/: updated
Thu Mar 31  2005   S Nishizawa
	* grib.rb: remove @define_mode and Grib#enddef
	           change value by units to write
	* varraygrib.rb: change as removing Grib#enddef
	* gphys_grib_io.rb: small change in test
Thu Mar 31  2005   T Horinouchi
	* grib.rb: Grib: eliminated @mode and introduced @define_mode
	  (It is a half-hearted job, since no @define_mode check is
	  introduced in the write method)
Thu Mar 31  2005   T Horinouchi
	* grib.rb: minor update of Grib#initialize (to refuse "w+"; 
	  corresponding error message at l.1268; documentation of file mode).
Wed Mar 30  2005   R Mizuta
	* gphys_grads_io.rb, varraygrads.rb:

	  gives more readable control file in GrADS output
	* gphys_grads_io.rb: bug in the test code fixed
Tue Mar 29  2005   T Horincouhi
	* gphys_io.rb: Added methods parse_gturl and open_gturl
	  (the former was moved from bin/gpprint to gphys_io.rb).
