This package provides access to the platform-independent Tcl scripting
language and Tk GUI elements. See TkWidgets for a list of
supported widgets, TkWidgetcmds for commands to work with them,

Note that Tk will not be initialized if there is no DISPLAY
variable set, but Tcl can still be used. This is most useful to allow
the loading of a package which depends on tcltk in a session that
does not actually use it (e.g., during installation).
