with the major functionality and optimizations by Oleg Moskalenko. It is compatible with the latest version of POSIX and the current GNU sort version that we have in base. Beside this, it implements all the functionality introduced in later versions of GNU sort. For now, it will be installed as "bsdsort", keeping GNU sort as the default sort implementation.
