    <title>Introduction to libblockdev</title>

    <para>
      libblockdev is a C library supporting GObject Introspection for
      manipulation of block devices. It has a plugin-based architecture where
      each technology (like LVM, Btrfs, MD RAID, Swap,...) is implemented in a
      separate plugin, possibly with multiple implementations (e.g. using LVM
      CLI or the new LVM DBus API).
