1996 # build a shared library consisting of all given .o files. All libraries
1997 # (.a) will be first decompressed into component .o files then act as

1999 # which will be put into .DLL. To see the list of accepted options (as well
2000 # as command-line format) simply run this program without options. The .DLL
2001 # is built to be imported by name (there is no guarantee that new versions
