function laprint(figno,filename,varargin)
%LAPRINT prints a figure for inclusion in LaTeX documents.
%  LaPrint creates an eps-file and a tex-file. The tex-file contains
%  the annotation of the figure such as titles, labels and texts. The
%  eps-file contains the non-text part of the figure as well as the 
%  position of the text-objects. The packages 'graphicx' (or 'epsfig')
%  and 'psfrag' (and possibly ''color'') are required for the LaTeX 
%  run. A postscript driver like 'dvips' is required for printing. 
%
%% Syntax
%  >> laprint
%
%  This opens a graphical user interface window, to control the
%  various settings. It includes a help facility. Just try it.
%
%  As an alternative to the GUI you can call laprint from the command
%  line with various extra input arguments. These arguments are 
%  explained in the help window of the GUI, which can be also be 
%  opened using the command
%  >> laprint helpwindow
