	As I've just checked, while the ‘x11’ and ‘qt’ drivers are
	provided as external binaries (under lib/gnuplot/), the ‘wxt’
	one is apparently compiled into the main gnuplot binary itself.

	If I'm right in my guess that the library dependencies of the
	latter on the Qt libraries are superfluous (I hope to check it
	the next week), then that may be one more reason to keep the
	‘wxt’ driver separate.

	Should my assumptions be right, I'd suggest the binary packages
	to be as follows:

    gnuplot

	provides /usr/bin/gnuplot compiled /with/ wxWidgets;

    gnuplot-nox (or gnuplot-nowx?)

	provides /usr/bin/gnuplot compiled /without/ wxWidgets;

    gnuplot-x11

	provides gnuplot_x11 only; Depends: gnuplot | gnuplot-nox;

    gnuplot-qt

	provides gnuplot_qt only; Depends: gnuplot | gnuplot-nox.

	Also, the layout above could reduce the package sizes somewhat,
	as there would only be two (instead of three) packages holding
	all the share/ stuff.

	Alternatively, share/ could be split off to a single
	gnuplot-common instead.

	First of all, I do not contest the clarity.

	Second, the present state of affairs is that the user isn't
	allowed to install the ‘x11’ driver without also installing
	libwxgtk2.8-0, like:

# apt-get install -V -- gnuplot-x11 libwxgtk2.8-0-

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gnuplot-x11 : Depends: libwxgtk2.8-0 (>= 2.8.12.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

	While I believe that the ‘x11’ driver /per se/ is (still)
	perfectly usable without wxWidgets.
