795 # dllar - a tool to build both a .dll and an .a file

797 #
798 # Written by Andrew Zabolotny, bit@freya.etu.ru
799 # Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
800 #
801 # This script will accept a set of files on the command line.
802 # All the public symbols from the .o files will be exported into
803 # a .DEF file, then linker will be run (through gcc) against them to
804 # build a shared library consisting of all given .o files. All libraries
805 # (.a) will be first decompressed into component .o files then act as
806 # described above. You can optionally give a description (-d "description")
807 # which will be put into .DLL. To see the list of accepted options (as well
808 # as command-line format) simply run this program without options. The .DLL
809 # is built to be imported by name (there is no guarantee that new versions
810 # of the library you build will have same ordinals for same symbols).
