DESCRIPTION
The
utility is a local GEOM Gate class consumer.
It can be used as a replacement for

``GEOMificator''
for non GEOM-aware devices, but it was mainly created as an example
on how to use and how to communicate with the GEOM Gate kernel module.
Available commands:
create
Create a
ggate
provider related to the given regular file or device.

Attach a worker process to an existing
ggate
provider.
