- Major cleanup in general.
    - Added --{build-{scripts,steps},help,tarball}. Variables can now
      be overriden on the command-line.
    - Integrated bzip2, dash, less, ncurses, popt, rsync, tar, util-linux,
      which, and xz; as there are no patches in portage/ for util-linux just
      yet, this presently requires integrated local patches. Git is included
      in build.vars only as it requires OpenSSL.
    - Include ntapi.local.patch and psxscl.local.patch in the repository.
