    <para>
      <application>libdrm</application> provides a user space library for
      accessing the DRM, direct rendering manager, on operating systems that
      support the ioctl interface. libdrm is a low-level library, typically used
      by graphics drivers such as the Mesa DRI drivers, the X drivers, libva and
      similar projects.
