% psboxes.sty
%
% This package enables to put a PostScript drawing behind a TeX box.
% The drawing is parametrized by the position and the size of the
% TeX box. To put a gray [rounded] box behind a word use
% \PScommands % Once at the begining
%
% ... text text \psboxit{25 cartouche}{THE WORD} text text
% \psboxit{box 0.5 setgray fill}{\spbox{ANOTHER WORD}}
% text text ...
%
% * If your boxes are ill sized try to change 16384 to
% something else (original code used 65536).
% % 65536 is the internal unit of TeX (scaled point, TeXBook page 57)
% Those macros were adapted from Tom Sheffler (CMU)'s psframe.sty style. In
% particular, the spacebox macro was just copied from his style.

%
% A Few PostScript definitions to use with \psboxit
% Call \PScommands once at the begining of your program, this will
% define : box roundedbox rectcartouche and cartouche. They are 4
% PostScript programs. Change the values before setlinewidth end
% setgray to customize your boxes
%
% Ex : \psboxit{25 cartouche}{blah blah}
% \psboxit{rectcartouche}{blah blah}

%% give some space around the text.

%% \psboxit{box 0.5 setgray fill}{\spbox{Some Text}}

% SPACEBOX
%
% This macro simply takes some TeX stuff, and puts FOUR sides on it
% so that the box is the same size as the thing you'd get with
% an \fbox{} command. (All I did was modify the code for \fbox{}
% so that all rules were replaced with struts).
%
% USAGE: \spbox{text} is just like \fbox{text} but makes no rules
%
% REASON: so that if using \pspath{...}{\fbox{stuff}}
% there is a way to get another box the same size:
% \pspath{...}{\spbox{stuff}}
