 772 #  Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
 773 #
 774 #  This script will accept a set of files on the command line.
 775 #  All the public symbols from the .o files will be exported into
 776 #  a .DEF file, then linker will be run (through gcc) against them to
 777 #  build a shared library consisting of all given .o files. All libraries
 778 #  (.a) will be first decompressed into component .o files then act as
 779 #  described above. You can optionally give a description (-d "description")
 780 #  which will be put into .DLL. To see the list of accepted options (as well
 781 #  as command-line format) simply run this program without options. The .DLL
 782 #  is built to be imported by name (there is no guarantee that new versions
 783 #  of the library you build will have same ordinals for same symbols).
