	1982	# dllar - a tool to build both a .dll and an .a file
	1983	# from a set of object (.o) files for EMX/OS2.
	1984	#
	1985	# Written by Andrew Zabolotny, bit@freya.etu.ru
	1986	# Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
	1987	#
	1988	# This script will accept a set of files on the command line.
	1989	# All the public symbols from the .o files will be exported into
	1990	# a .DEF file, then linker will be run (through gcc) against them to
	1991	# build a shared library consisting of all given .o files. All libraries
	1992	# (.a) will be first decompressed into component .o files then act as
	1993	# described above. You can optionally give a description (-d "description")
	1994	# which will be put into .DLL. To see the list of accepted options (as well
	1995	# as command-line format) simply run this program without options. The .DLL
	1996	# is built to be imported by name (there is no guarantee that new versions
	1997	# of the library you build will have same ordinals for same symbols).
