GETTING STARTED WITH SAOTNG

	(1) The Correct Path

	    SAOtng may have been installed in a non-traditional
	    directory.  Such a capability is supported so that users
	    can build and access SAOtng without the need of system
	    manager support.  If this has been done at your site,
	    please ensure that you have placed the bin directory
	    containing SAOtng and related programs in your path.

	    Normally, this is done by adding that directory to
	    the 'path' environment variable  in the .cshrc file
	    (csh and tcsh users) or your 'PATH' environment variable
	    in the .profile file (sh and ksh users).

	(2) Start Up SAOtng

	    The SAOtng system is started up using the saotng script:

		saotng [command options] [filename]

	    Command options and filenames are documented in the SAOtng
	    help facility.


	Notes:

	1. Please execute the 'saotng' script, not the 'SAOtng' program.
	The 'saotng' script is required to set the environment properly;
	you are unlikely to get good results from the 'SAOtng' program
	by itself.  You also are unlikely to get good results if you
	start saotng using a full pathname, without having the saord bin
	directory in your path.

	2. IRAF users -- to connect tv/display to SAOtng, please use the
	switches:

		saotng -input_fifo <ipipe> -output_fifo <opipe>

	e.g.

		saotng -input_fifo /dev/imt1i -output_fifo /dev/imt1o

	Alternatively, you can set the environment variables:

		setenv SAOTNG_IFIFO <ipipe>
		setenv SAOTNG_OFIFO <opipe>

	in your .login file to avoid using command line switches.
	(NB: SAOtng will display IRAF .imh and .qp files directly, without
	using tv/display.)
