% Insert a PostScript plot made by IDL into a LaTex document:
% For the ArborText program dvips.

% Usage: \insertplot{file}{caption}{label}{width}{height}
% 	file = name of file containing the PostScript.
% 	caption = caption of figure
%	label = latex \label{} for figure to be used by \ref{} macro.
%	width = width of figure in inches.
%	height = height of figure, in inches.
