______________________________________________________________________________
itkvars − variables used by [incr Tk] _________________________________________________________________
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.
