A *(Unix)-like *(OS) of the *(BSD) family. From its home page (see below):

<blockquote>
DragonFly is an operating system and environment designed to be the logical continuation of the _(FreeBSD)-4.x OS series. These _(operating systems) belong in the same class as _(Linux) in that they are based on _(UNIX) ideals and _(API)s. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the _(FreeBSD)-5 series.
