+%%%%%%%%%%%%% SPRITE.STY %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%% LaTeX style option SPRITE.STY ( Martin Costabel 27-Oct-1987 )
+%% Use: \documentstyle[...,sprite,...]{...}
+%\makeatletter          %use this if you \input{sprite.sty}
+%% New command:
+%%
+%% \sprite{cmd}(lins,cols)[wdth,hght] pixels \endsprite
+%%
+%% Here:
+%% cmd is a command sequence which is afterwards the name of the new object.
+%%     It is defined as \usebox{cmd@box}, so there is also a new box cmd@box.
+%% wdth and hght are the width and height of the new object.
+%% pixels is a sequence of lins lines, each of which starts with a `:'(colon),
+%%     ends with a `|'(vertical bar), and contains cols pixels which are
+%%     either a `.'(period, meaning a white pixel) or a `B'(capital B, meaning
+%%     a black pixel). Blank spaces are ignored.
