NAME
     rstart - a sample implementation of a Remote Start client

SYNOPSIS
     rstart [-c context] [-g] [-l username] [-v] hostname command
     args ...

DESCRIPTION
     Rstart is a simple implementation of a Remote  Start  client
     as defined in "A Flexible Remote Execution Protocol Based on
     rsh".  It  uses  rsh  as  its  underlying  remote  execution
     mechanism.

OPTIONS
     -c context
             This option  specifies  the  context  in  which  the
             command is to be run.  A context specifies a general
             environment the  program  is  to  be  run  in.   The
             details  of  this environment are host-specific; the
             intent is that the client  need  not  know  how  the
             environment  must  be  configured.   If omitted, the
             context defaults to X.  This should be suitable  for
             running   X  programs  from  the  host's  "usual"  X
             installation.

     -g      Interprets  command  as  a   generic   command,   as
             discussed   in   the  protocol  document.   This  is
             intended to allow common applications to be  invoked
             without  knowing  what they are called on the remote
             system.   Currently,  the  only   generic   commands
             defined are Terminal, LoadMonitor, ListContexts, and
             ListGenericCommands.

     -l username
             This option is passed  to  the  underlying  rsh;  it
             requests  that  the  command be run as the specified
             user.

     -v      This option requests that rstart be verbose  in  its
             operation.   Without  this  option,  rstart discards
             output from the remote's rstart helper, and  directs
             the rstart helper to detach the program from the rsh
             connection used to  start  it.   With  this  option,
             responses  from  the  helper  are  displayed and the
             resulting  program  is   not   detached   from   the
             connection.

NOTES
     This is a trivial implementation.   Far  more  sophisticated
     implementations are possible and should be developed.


     Error handling is nonexistant.  Without  -v,  error  reports
     from  the  remote  are  discarded  silently.  With -v, error
     reports are displayed.

     The $DISPLAY environment variable is passed.  If  it  starts
     with  a  colon,  the local hostname is prepended.  The local
     domain name should be appended to  unqualified  host  names,
     but isn't.

     The $SESSION_MANAGER environment variable should be  passed,
     but isn't.

     X11 authority information is passed for the current display.

     ICE authority information should be passed, but  isn't.   It
     isn't  completely  clear  how  rstart should select what ICE
     authority information to pass.

     Even without -v, the sample rstart helper will leave a shell
     waiting  for  the  program to complete.  This causes no real
     harm and consumes relatively few resources,  but  if  it  is
     undesirable  it  can be avoided by explicitly specifying the
     "exec" command to the shell, eg

          rstart somehost exec xterm

     This is obviously dependent on the command interpreter being
     used  on  the remote system; the example given will work for
     the Bourne and C shells.
