1413 # This script will accept a set of files on the command line.
1414 # All the public symbols from the .o files will be exported into
1415 # a .DEF file, then linker will be run (through gcc) against them to
1416 # build a shared library consisting of all given .o files. All libraries
1417 # (.a) will be first decompressed into component .o files then act as
1418 # described above. You can optionally give a description (-d "description")
1419 # which will be put into .DLL. To see the list of accepted options (as well
1420 # as command-line format) simply run this program without options. The .DLL
1421 # is built to be imported by name (there is no guarantee that new versions
1422 # of the library you build will have same ordinals for same symbols).
