##!\arguments{
##!  \item{id}{The job-id which is the output from \code{inla} when the job is submitted,  the
##!            job-number or job-name. For \code{inla.qstat}, \code{id} is optional and if omitted
##!            all the jobs will be listed.}
##!  \item{remove}{Logical If FALSE, leave the job on the server after retrival,
##!                otherwise remove it (default).}
##!  \item{x}{An \code{inla.q}-object which is the output from \code{inla.qstat}}
##!  \item{object}{An \code{inla.q}-object  which is the output from \code{inla.qstat}}
##!  \item{...}{ other arguments.}
##!}
##!\details{
##!\code{inla.qstat} show job(s) on the server,
##!\code{inla.qget} fetch the results (and by default remove
##!the files on the server),  \code{inla.qdel} removes 
##!a job on the server and \code{inla.qnuke} remove all jobs on the server.
##!\code{inla.qlog} fetches the logfile only.
##!
##!The recommended procedure is to use \code{r=inla(...,
##!inla.call="submit")} and then do \code{r=inla.qget(r)} at a later
##!stage.  If the job is not finished, then \code{r} will not be
##!overwritten and this step can be repeated.  The reason for this
##!procedure, is that some information usually stored in the result
##!object does not go through the remote server, hence have to be
##!appended to the results that are retrieved from the server. Hence
##!doing \code{r=inla(..., inla.call="submit")} and then later retrive
##!it using \code{r=inla.qget(1)}, say, then \code{r} does not contain
##!all the usual information.  All the main results are there, but
##!administrative information which is required to call
##!\code{inla.hyperpar} or \code{inla.rerun} are not there.
##!}
##!\value{
##!  \code{inla.qstat} returns an \code{inla.q}-object with information about current jobs.
