+==================================================
+ rbd-ggate -- map rbd images via FreeBSD GEOM Gate
+==================================================
+
+.. program:: rbd-ggate
+
+Synopsis
+========
+
+| **rbd-ggate** [--read-only] [--exclusive] [--device *ggate device*] map *image-spec* | *snap-spec*
+| **rbd-ggate** unmap *ggate device*
+| **rbd-ggate** list
+
+Description
+===========
+
+**rbd-ggate** is a client for RADOS block device (rbd) images. It will
+map a rbd image to a ggate (FreeBSD GEOM Gate class) device, allowing
+access it as regular local block device.
+
+Commands
+========
+
+map
+---
+
+Spawn a process responsible for the creation of ggate device and
+forwarding I/O requests between the GEOM Gate kernel subsystem and
+RADOS.
+
+unmap
+-----
+
+Destroy ggate device and terminate the process responsible for it.
+
+list
+----
+
+List mapped ggate devices.
+
+Options
+=======
+
+.. option:: --device *ggate device*
+
+   Specify ggate device path.
+
+.. option:: --read-only
+
+   Map read-only.
+
+.. option:: --exclusive
+
+   Forbid writes by other clients.
+
+Image and snap specs
+====================
+
+| *image-spec* is [*pool-name*]/*image-name*
+| *snap-spec*  is [*pool-name*]/*image-name*\ @\ *snap-name*
+
+The default for *pool-name* is "rbd".  If an image name contains a slash
+character ('/'), *pool-name* is required.
+
+Availability
+============
+
+**rbd-ggate** is part of Ceph, a massively scalable, open-source,
+distributed storage system. Please refer to the Ceph documentation at
+http://ceph.com/docs for more information.
