Installation notes for IRAF
---------------------------

Please follow the instructions in general.readme before attempting to use IRAF.

Login as superuser (root)

Type the following commands to create the `pipe's which IRAF uses to communicate
with its image display servers.

	mknod -m 777 /dev/imt1i p
	mknod -m 777 /dev/imt1o p
	ln -s /dev/imt1o /dev/imt1


If your system does not have the file /etc/utmp, create a link

	ln -s /var/run/utmp /etc/utmp

   OR

	ln -s /var/adm/utmp /etc/utmp


Create the following links 

        ln -s /astro /iraf
	ln -s /astro/iraf/dev/imtoolrc /usr/local/lib/imtoolrc
	ln -s /astro/iraf/unix/hlib/libc/iraf.h /usr/include/iraf.h


depending upon the actual loction of the file on your system.


The /home/astro directory is automatically setup to run IRAF and has a
default login.cl file and uparm directory.

An easy startup script is provided which starts up both SAOimage and an 
IRAF command line.



	cd /home/astro
	./start.iraf

To test that IRAF is communicating with SAOimage properly type the following


	dataio
	rfits m51.fits 
	m51
	tv
	display m51 1

after a while the familiar image of M51 should appear in the SAOimage window.


To enable other accounts for use with IRAF, just follow the normal procedure
of adding the enviroment variable `iraf' (defined as /astro/iraf/)
to the users login script. Then add `/astro/bin' to the users PATH.
Log in as the user and type 'mkiraf' to create
the IRAF login.cl and uparm directory. Optionally copy the start.iraf
file to the users login directory.

There is extensive documentation available from within IRAF (type help), 
and from within the integrated HTML documentation tree (see htmldocs.readme).

Printable documents are also available in /astro/iraf/doc.
