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 compiled-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.
