    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.
