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