% This macro inserts pictures (and, more generally, \vbox es) neatly
% into the MIDDLE of a paragraph.
% --- #1 should be a \vbox ---
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% These macros insert (\vbox es) using respectively \topinsert and
% \pageinsert. Since these macros put you into vertical mode,
% they should only be called BETWEEN paragraphs.
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% To define a \vbox for an inserted figure, use the following command:
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% \Picture\CompEP\height=4.125in \width=\hsize\caption{\narrower
% The caption goes here.}
% \savepicture\FigureOne
% (\Picture calls \FIG and assigns the figure the caption
% indicated and the figure number \CompEP. It also
% creates a \vbox of the right size for a picture
% of the indicated height, and \savepicture assigns this
% to the macro \FigureOne.)
