+% The goal of this command is to darken the background of any box -
+% text, figure, table etc. In the contrast to PostScript drivers,
+% DVIWIN etc. there is not used any driver-specific properties, but
+% standard Plain(La) TeX. Small black squares is places in the area
+% of the box. The dimension of black square (length \deltablack) may be
+% set by any means (\setlength). But it's reasonable to choose
+% this dimension little greater than dimension of point of the
+% output printer. By default it is equal to 0.3pt, that is suitable
+% for the printer of 300 dpi.
+%
+% The degree of darkness is regulated by means of change the distance
+% between small black squares. In this style squares are placed in the
+% rectangular order - it's simpler, but result is not always very good.
+% - See the style "shadbox1.sty".
+%
+% The retribution for driver-independence is: the less squares and
+% nearer to each other, the greater the size of output DVI-file (and
+% grows quickly). One must experiment to find balance between quality
+% of shadow and size of output file.
+%
+%
+%
+% You may change this code freely. But please inform me if you use
+% or improve these commands.
+%
+%
+%
+% Usage:
+%
+% \shadbox{x}{abc}
+%
+% x - ratio showing how many times the distance between squares
+% greater than their size (may be only >1). 1 corresponds
+% to black darkness, 2 corresponds to 50% darkness.
+%
+% abc - the box, which must be darken
