* The G_FLAG_VERBOSE flag on a command specification means that the
* command will accept a -v option and the GEOM framework will print
* out status information after the command when it is run with -v.
* Additionally a GEOM command can explicitly specify a -v option and
* handle it as it would any other option. If both a -v option and
* G_FLAG_VERBOSE are specified for a command then both types of verbose
* information will be output when that command is run with -v.
*
* When the G_FLAG_LOADKLD is specified for a command, the GEOM kernel
* module will be loaded when that command is run if it has not yet been
* loaded. This flag is typically specified for the `create' command.
