-# This script will take a number ($ENV{SCRIPT_INPUT_FILE_COUNT}) of static archive files
-# and pull them apart into object files. These object files will be placed in a directory
-# named the same as the archive itself without the extension. Each object file will then
-# get renamed to start with the archive name and a '-' character (for archive.a(object.o)
-# the object file would becomde archive-object.o. Then all object files are re-made into
-# a single static library. This can help avoid name collisions when different archive
-# files might contain object files with the same name.
