583 * values, DISTRIB_ID (distributor/distribution name),
584 * DISTRIB_RELEASE (release number of the distribution),
585 * DISTRIB_DESCRIPTION (*might* be name followed by version,
586 * but the manpage for lsb_release seems to indicate that's
587 * not guaranteed), and DISTRIB_CODENAME (code name, e.g.
588 * "licentious" for the Ubuntu Licentious Lemur release).
589 * the lsb_release man page also speaks of the distrib-release
