% To use PSbox, look in the postscript file.  There will be a
% comment about the bounding box.  It will be four numbers, say
% a, b, c, d
% To use this to include the file at full scale, say
% \PSbox{filename}{a}{b}{c}{d}{1}
% The last number is the scale.  If it is other than 1, you will
% have to multiply a, b, c, and d by it yourself.
