Subject: - 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.
