1962 # Written by Andrew Zabolotny, bit@freya.etu.ru
1963 # Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
1964 #
1965 # This script will accept a set of files on the command line.
1966 # All the public symbols from the .o files will be exported into
1967 # a .DEF file, then linker will be run (through gcc) against them to
1968 # build a shared library consisting of all given .o files. All libraries
1969 # (.a) will be first decompressed into component .o files then act as
1970 # described above. You can optionally give a description (-d "description")
1971 # which will be put into .DLL. To see the list of accepted options (as well
1972 # as command-line format) simply run this program without options. The .DLL
1973 # is built to be imported by name (there is no guarantee that new versions
1974 # of the library you build will have same ordinals for same symbols).
