	1936	# dllar - a tool to build both a .dll and an .a file
	1937	# from a set of object (.o) files for EMX/OS2.
	1938	#
	1939	# Written by Andrew Zabolotny, bit@freya.etu.ru
	1940	# Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
	1941	#
	1942	# This script will accept a set of files on the command line.
	1943	# All the public symbols from the .o files will be exported into
	1944	# a .DEF file, then linker will be run (through gcc) against them to
	1945	# build a shared library consisting of all given .o files. All libraries
	1946	# (.a) will be first decompressed into component .o files then act as
	1947	# described above. You can optionally give a description (-d "description")
	1948	# which will be put into .DLL. To see the list of accepted options (as well
	1949	# as command-line format) simply run this program without options. The .DLL
	1950	# is built to be imported by name (there is no guarantee that new versions
	1951	# of the library you build will have same ordinals for same symbols).
