\begin{Description}\relax
Interface and language bindings to Tcl/Tk GUI elements.
\end{Description}
\begin{Details}\relax
This package provides access to the platform-independent Tcl scripting
language and Tk GUI elements.  See \LinkA{TkWidgets}{TkWidgets} for a list of
supported widgets, \LinkA{TkWidgetcmds}{TkWidgetcmds} for commands to work with them,
and references in those files for more.  

The Tcl/Tk documentation is in
the system man pages.

For a complete list of functions, use \code{ls("package:tcltk")}.

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