1967# dllar - a tool to build both a .dll and an .a file
1968# from a set of object (.o) files for EMX/OS2.
1969#
1970# Written by Andrew Zabolotny, bit@freya.etu.ru
1971# Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
1972#
1973# This script will accept a set of files on the command line.
1974# All the public symbols from the .o files will be exported into
1975# a .DEF file, then linker will be run (through gcc) against them to
1976# build a shared library consisting of all given .o files. All libraries
1977# (.a) will be first decompressed into component .o files then act as
1978# described above. You can optionally give a description (-d "description")
1979# which will be put into .DLL. To see the list of accepted options (as well
1980# as command-line format) simply run this program without options. The .DLL
1981# is built to be imported by name (there is no guarantee that new versions
1982# of the library you build will have same ordinals for same symbols).
