2205 # dllar - a tool to build both a .dll and an .a file
2206 # from a set of object (.o) files for EMX/OS2.
2207 #
2208 # Written by Andrew Zabolotny, bit@freya.etu.ru
2209 # Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
2210 #
2211 # This script will accept a set of files on the command line.
2212 # All the public symbols from the .o files will be exported into
2213 # a .DEF file, then linker will be run (through gcc) against them to
2214 # build a shared library consisting of all given .o files. All libraries
2215 # (.a) will be first decompressed into component .o files then act as
2216 # described above. You can optionally give a description (-d "description")
2217 # which will be put into .DLL. To see the list of accepted options (as well
2218 # as command-line format) simply run this program without options. The .DLL
2219 # is built to be imported by name (there is no guarantee that new versions
2220 # of the library you build will have same ordinals for same symbols).
