NAME
  rstart - a sample implementation of a Remote Start client

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

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.

DESCRIPTION
  The rstart command 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.

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

  Error handling is nonexistent.  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 is not.

  The $SESSION_MANAGER environment variable should be passed, but is not.

  X11 authority information is passed for the current display.

  ICE authority information should be passed, but is not.  It is not
  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, for example,

       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.
