Version 0.7.1a -> Version 0.7.2
   main improvement with the help of four(!) patches from Vadim Godunko.
   At this place I'd very much like to express my gratitude to him.
   - improved makefallb
   - change types from Ada-types to Interfaces.C-types wherever necessary to
     ensure correct data size independend of architecture or compiler
     Mapping Ada-type <-> C-type is not necessarily 1:1 as it is with GNAT
     Sorry, this will almost certainly break some applications
   - in x_lib.ads:
      add X_Create_Simple_Window
      move X_*_Event representative clause into private area to satisfy GNAT 3.14p
   - in x_lib-extensions-print.ad?:
      add Xp_Get_Locale_Net_String and Xp_Notify_Pdm
   - in x_toolkit.ads:
      add type Cardinal_Array
   - in xm_widgets-manager-spin_box spec. and body:
      add Arrow_Orientation resource and Wrap constraint resource
   - in xm_widgets-protocols spec. and body:
      add Null_Xt_Pointer as default value of Closure in
      Xm_Add_Protocol_Callback, Xm_Add_WM_Protocol_Callback,
      Xm_Remove_Protocol_Callback, Xm_Remove_WM_Protocol_Callback
   - in xm_widgets:
      define Xm_String_Tag_Array, Xm_Tab_List
      add tab list related routines Xm_String_Table_Propose_Tablist and
      Xm_Tab_List_Free
      change Xm_Rendition_Free, Xm_Render_Table_Free, Xm_Parse_Mapping_Free,
      Xm_Parse_Table_Free, Xm_String_Free, Xm_String_Free_Context
      argument access
      add functions Xm_Render_Table_Copy, Xm_Render_Table_Get_Rendition
      add type Orientation with Append_Set and Append_Get routines
      (replaces multiple occurences, in Xm_Widgets.Manager.Paned_Window,
       Xm_Widgets.Manager.Row_Column, Xm_Widgets.Manager.Scale,
       Xm_Widgets.Primitive.Scroll_Bar, Xm_Widgets.Primitive.Separator)
   - new packages Xm_Widgets.Print (Print support via X Print Protocol)
                  X_Wide_Strings, Xm_Widgets.Manager.Row_Column.Simple
   - minor modifications for GNAT 3.14p compatibility in
     xm_widgets-drag_context.ads
     (see there)
   - new package Xm_Widgets-Manager-Spin_Box-Simple:
      only available in Motif 2.1 and later
   - major improvements of the example programs xmmore, clock and mandel
   - some bug fixes (remove memory leaks, make work-around for bug in
     Gnat 3.13p runtime lib)
   - add new sort and search routines (in directory generic)
   - new example program show_printers
      (needs X-Print Server, started e.g. by Xprt :1 &)
   - new example program xau_test

ATTENTION: changes to Local.conf
   - define new variable GNAT313p_BUG in Local.conf
   - add new variable XP_LIB in Local.conf

since Version 0.7
   - put the binding itself under a less restrictive copyright similar to that
     of GNAT. This allows the unrestricted incorporation of the binding even in
     commercial and classified programs

since Version 0.61
   - adapted complete package to Motif2.1 (in Local.conf set IS_MOTIF21 to 1,
     don't set IS_MOTIF20 !) and added support for X11R6.3 (IS_X11R63)
   - corrected the name of the resource Xm_N_Through_Color in
     Xm_Widgets.Primitive.Scroll_Bar
   - corrected the name of the resource Xm_N_Select_Color in
     Xm_Widgets.Primitive.List
   - changed name of type Edit_Mode_Type to Edit_Mode in
     Xm_Widgets.Primitive.CS_Text (was already changed in
     Xm_Widgets.Primitive.Text)
   - changed Value of State_Type to Withdrawn (added trailing "n") in
     X_Lib.Property
   - added "_Type" to types Audible_Warning, Delete_Response,
     Keyboard_Focus_Policy and Input_Policy in Xm_Widgets.Shell
   - renamed package X_Lib.Atoms to X_Lib.Predefined_Atoms
   - renamed State_Type in X_Lib.Property to Window_State
   - moved routines concerning X_lib extensions to new package X_Lib.Extensions
   - created new package X_Lib.Extensions.Print (Print extension, not yet
     tested, only for X11R6.3)
   - added new package X_Auth (authorization)
   - moved definition of Protocol_Family (former Host_Family) and
     Net_Address (former Host_Family) to new package X_Connection
   - changed the Mandel example program. With gnat 3.12p on Linux 2.3.x with
     Motif2.1, XFree86 3.3.6 and glibc 2.1 it calculates the Mandelbrot set
     using 10 threads! Note: for this example program your Motif and the
     X libraries must be thread safe
   - include additions and changes from Vadim Godunko (vadik@zto.rost.ru)
   - bug fixes, thank you for the bug reports, James Bean and Joerg Schaefer
   - many minor changes
   - put the code under GNU General Public License

since Version 0.6:
   - removed error in utils/xpm2axpm.adb (corrected in patch 1)

since Version 0.5:
   - added X_Create_Bitmap_From_Data, X_Query_Best_Stipple, X_Query_Best_Tile,
     X_Restack_Windows and procedures for private color cells
     (X_Alloc_Color_Cells, X_Alloc_Color_Cells, X_Store_*Color*) and the until
     then missing X_Free_Colors
     to X_Lib,
     X_Query_Best_Cursor and X_Recolor_Cursor
     to X_Lib.Cursor,
     X_Get_Standard_Colormap, X_Set_Standard_Colormap
     to X_Lib.Std_Colormap
   - moved type Window_ID_Array_Type from X_Lib.Property to X_Lib, because it is
     already used there
   - corrected call of X_Sync (had wrong number of parameters!)
   - changed procedure names in Xm_Widgets.Primitive.List to be similar to the
     C-Interface of M*tif and also changed some type names
   - changed Append and Element routines in X_Toolkit.Resource so that for
     Resource_Size the Ada 'Size attribute can be used
     (Resource_Size is now in bits, not in bytes)
   - changed import interface definition of some routines (defined as function
     returning an integer in the Xlib C-interface, but in fact being a
     procedure, e.g. XFreeColors)
   - changed the functions in X_Image X_Image_Funcs returning an integer
     to procedures
   - new package Interfaces.C.Strings.String_Lists handling C type char**
     parameters
   - completely rewrote X_Command_Line, put internally used procedures into
     child package X_Command_Line.Internal
   - renamed several packages:
        String_List_C_Interface  => String_List_Conversion (also changed)
	X_Toolkit.X_Private      => X_Toolkit.Internal
	X_Toolkit_Private        => Resource_Strings
	X_Lib.Resource.X_Private => X_Lib.Resource.Internal
   - corrected many errors in Xpm_Lib

Version 0.4 to 0.5:
   - changed "child type" constraint resources type to reflect the extension
     of this type by the class main window
   - added Image Cache functions to Xm_Widgets
   - added Parse Mapping/Parse Table functions to Xm_Widgets
     (e.g. Xm_String_Unparse)
   - changes to package X_Lib:
        o added simple types Bits_8, Bits_16 and Bits_32
          (necessary for data transfer e.g. window properties)
        o added X_Query_Tree
        o moved host access functions to new subpackage X_Lib.Host_Access
	o renamed and generalized subpackage X_Lib.Window_Manager to
	  X_Lib.Property
        o moved functions X_Intern_Atom and X_Get_Atom_Name to newly created
	  subpackage X_Lib.Property
        o added grab functions and several types connected to them
   - added to package X_Toolkit:
        o procedures Xt_Last_Event_Processed and Xt_Last_Timestamp_Processed
	o procedures Xt_Register_Drawable and Xt_Unregister_Drawable
        o procedure Xt_Set_WM_Colormap_Windows
        o procedures Xt_Find_File and Xt_Resolve_Pathname
   - removed from package X_Toolkit:
        o type Modifiers. It is replaced by the Modifiers_Mask_Type from X_Lib
   - added new package interfaces.c.wstrings similar to interfaces.w.strings,
     to support wchar_t*, i.e. C-style wide character strings
     (normally wchar_t /= Wide_Character, because wchar_t uses 32 bits but
      Wide_Character only 16 bits. it is therefore VERY INPORTANT that
      the constant wchar_t_bits in System.Parameters is correctly set for
      your os)
   - changed some type names in Xm_Widgets.Transfer
   - added many type names in Xm_Widgets.Manager.Container and also corrected
     many errors

   - IMPORTANT : changed To_Callback_Struct to return Callback_Struct_Access
                 instead of Callback_Struct_Recs, because sometimes the
                 Callback_Structs have to return parameters as well

Version 0.3 to 0.4:
   - exchanged "echo" with "printf". This solves a problem on strict SYSV
     systems
     thanks to Stephane Barbey (stephane.barbey@di.epfl.ch)
   - added many Xlib routines (X_Height_Of_Screen, X_Height_MM_Of_Screen,
     X_Width_Of_Screen, X_Width_MM_Of_Screen, X_Load_Font, X_Map_Window,
     X_Create_Window, X_Change_Window_Atttributes, X_Window_Events, ...)
   - new X_Lib sub-packages Std_Colormap and Window_Manager
   - removed error in X_Parse_Color
   - had to change Event_Type into an integer type (from enumeration type),
     because of the extensions defining their additional events
   - added Standard Colormap functions to X_Misc_Utils
   - changed Callback_Reason from enumeration type to a type derived from
     integer because of extensions which are then integrateable
     I got the hint in your comment to the GL widget, Chip (chipr@niestu.com)!
   - new example program "image" by Jim Bean
   - changed Depth-Parameter of Xt_Allocate_GC to type Color_Depth
   - new example program "mandel" which shows the multithreaded programming
     (runs with native threads and glibc2 based X libraries on Linux 2.*)

Version 0.2 to 0.3:
   - changed Keysym_ID to Key_Sym_ID to reflect spelling in X.h (KeySym)
   - added many Xlib routines
   - support Xlib procedures handling with Colormaps and Window properties
   - support low level Xt resource management (in X_Toolkit.Resource)
   - moved declaration of types Position and Dimension from X_Toolkit to X_Lib,
     because logically they are already needed there
   - added forms of Xm_Draw_String* without clip rectangle
   - replaced Interfaces.C.Strings.Chars_Ptr by the own type X_Strings.X_String
   - added (the forgotten) X_Error_Event to the X_Event record, restructured
     it
   - regrouped several Xlib items like cursors (added new package X_Lib.Cursor,
     removed package X_Lib.Cursorfont) and atoms
     (moved Atom query functions to X_Lib.Atoms)
   - removed many errors (and surely added some)

Version 0.1 to 0.2:
   - fixed record representations for big endian machines in special and
     for some records in general
   - added Xm_Add_To_Post_From_List function
   - clearyfied Callback_Struct conversion, checks included
   - new package Xm_Widgets.Transfer for selection mechanism
   - many changes in drag and drop packages
   - added XmTextField widget functions (in Xm_Widgets.Primitive.Text)
   - added Graphics Context declarations and functions
     in the X_Lib and X_Toolkit packages
   - added Xlib drawing and host list functions
   - added Colour allocation function

Version 0.1

   first release -- record representations were not applicable for big endian
   machines!
