	In the output file, say 'class_name.s' of short -i applied 
	on your Eiffel class file, add the following first line:
		.nr xM 1	
	which means in Troff language:
		``Define and auto-increment number register xM by 1''

	Then follow the Eiffel documentation and do:
		(nroff class_name.s > stdout_file) >& index
	To get an `index' file that you can then sort that way: 
		sort -du +0.3 -o index index
	(see sort (1) fore more details on sorting options).

	On thing that should also be mentioned is that the `index'
	file should be printed without the default Troff formating. 
	On way to do it is to add the following first line in your file:
		.nf
	which means in Troff language:
		``No filling or adjusting of output lines''

	The list of ancestors can only be printed separately 
	with command `ancestors'.
