	1959	# dllar - a tool to build both a .dll and an .a file
	1960	# from a set of object (.o) files for EMX/OS2.
	1961	#
	1962	# Written by Andrew Zabolotny, bit@freya.etu.ru
	1963	# Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
	1964	#
	1965	# This script will accept a set of files on the command line.
	1966	# All the public symbols from the .o files will be exported into
	1967	# a .DEF file, then linker will be run (through gcc) against them to
	1968	# build a shared library consisting of all given .o files. All libraries
	1969	# (.a) will be first decompressed into component .o files then act as
	1970	# described above. You can optionally give a description (-d "description")
	1971	# which will be put into .DLL. To see the list of accepted options (as well
	1972	# as command-line format) simply run this program without options. The .DLL
	1973	# is built to be imported by name (there is no guarantee that new versions
	1974	# of the library you build will have same ordinals for same symbols).
