function figfile(varargin)
% FIGFILE       printing function for FIG-figures
% Prints named figure(s) to eps-file(s) with same name(s), or to
% printer. If no name is given, current figure is printed to a file named 
% after current figure's nametag. 
%
% figfile(varargin)
%
% NAMES OF FIGURES to print may be input as separate strings and/or
%               cellstring arrays. Cellstring arrays might be useful when
%               automizing printing in a script, and separate string input
%               is handy when printing selected figures from command line,
%               but they can be mixed. Wildcards (*) may be used, and '*'
%               alone prints all open figures. 
%
% OPTIONS       string input starting with a '-' (minus) followed by any
%               of the following characters:
%               
%			'k' - b/w eps-format (deps2)
%                       'g' - colormap gray and brighten(.5)
%                       's' - figstamp on figure
%                       'n' - figstamp w/name on figure
%                       'p' - to paper
%			'F' - PaperPosition full page
%			'L' - PaperOrientation landscape
%			'P' - PaperOrientation portrait
%
%		Furthermore printername can be specified in separate
%		string input starting with '>'.
%
% EXAMPLES      Command line no bracket syntax:
%                       FIGFILE afigure anotherfigure anuglyfigure      
%               With options 'to paper' and 'gray' on printer named 'hp4':
%                       FIGFILE -pg >hp4 afigure anotherfigure anuglyfigure
%               With cellstring object:
%                       myfigs={'afigure','anotherfigure','anuglyfigure'};
%                       FIGFILE(myfigs);
%                       FIGFILE('-pg',myfigs);
%               Print all open figures named 'an...':
%                       FIGFILE an*
