-A `frequently asked question' is that for possibilites to produce
-shaded boxes.
-
-Since the answers usually (just as recently) point either to PostScript
-\special's and PiCTeX it seems that a `simpler' and easier to use version
-is not readily available --- though I did not check this.
-
-A small and simple approach to shaded boxes is the use of a special font
-providing shaded rectangles, and some macros which automatically compose the
-desired box from these characters.
-
-Since, of course, the finest shading can be achieved by using single pixels
-for the pattern, the best shading pattern is *device dependent*.
-Furthermore, one generally defined shading pattern would imply the danger,
-that - because of rounding errors - at the boundaries (between two of the
-characters) `lines' would occur, and that the pattern would not look completely
-uniform.  Consequently, since different fonts are to be used for different
-printers, the dvi file is *device dependent* in this sense, too, though the
-code - both for the macros and for the metafont description - is device
-independent.

-
-{\tt SHADE} is a \TeX\ tool that can be used to produce shaded boxes
-neither using PostScript nor Pic\TeX.
-
-% The syntax is:
-
-\shade{This text will appear on a shaded background!}
-
-The shading macro first packs its argument into an hbox.
-
-\shade{\vbox{\hsize 5cm
-       \leftskip=0pt plus 1fil\rightskip=0pt plus 1fil
-       \parfillskip=0pt
-       Then it measures the dimensions of this box and produces a
-       shaded box slightly larger then this box, using the font
-       shade produced by {\tt shade.mf}. Finally it
-       puts the box back and overlays it with the shaded box.
-       \par
-      }}
-
-Since the best shading is achieved at the lowest possible resolution,
-the font \shade{SHADE} is {\bf not device independent} --- it uses
-the printer resolution. Therefore the .dvi file is
-{\bf not device independent}, either.
-The macro code, however, {\bf is device independent}.
-This method was used because otherwise shading, and in particular
-the boundaries between two shading characters, could turn out to be not
-completely uniform.
-For the same reason, the font should only be used at its true size.
-
-The {\tt shade} package consists of three files:
-    {\tt shade.mf,           % MetaFont file for shading font
-         shade.tex,          % macro file be used with LaTeX, too
-         shade.rdm.          % this file
-                            % it can be processed by TeX as a demo file
-       }
-It was tested with a HP Laserjet II plus.
