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).
