NAME
       itkvars - variables used by [incr Tk]
_________________________________________________________________

DESCRIPTION
       The  following  global variables are created and managed automatically by the [incr Tk] library.  Except where noted below, these variables
       should normally be treated as read-only by application-specific code and by users.

       itk::library
	      When an interpreter is created, [incr Tk] initializes this variable to hold the name of a directory containing the system library of
	      [incr Tk]  scripts.  The initial value of itk::library is set from the ITK_LIBRARY environment variable if it exists, or from a com-
	      piled-in value otherwise.

	      When [incr Tk] is added to an interpreter, it executes the script "init.itk" in this directory.  This script,  in  turn,	looks  for
	      other script files with the name "init.xxx".  Mega-widget libraries will be automatically initialized if they install a script named
	      "init.xxx" in this directory, where "xxx" is the name of the mega-widget library.  For example, the [incr Widgets] library  installs
	      the  script  "init.iwidgets"  in	this directory.  This script establishes the "iwidgets" namespace, and sets up autoloading for all
	      [incr Widgets] commands.
