-# dllar - a tool to build both a .dll and an .a file
-# from a set of object (.o) files for EMX/OS2.
-#
-#  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).
-#
-#  dllar is free software; you can redistribute it and/or modify
-#  it under the terms of the GNU General Public License as published by
-#  the Free Software Foundation; either version 2, or (at your option)
-#  any later version.
