Some time ago we started a project to develop prototype IRAF applications
with integral GUIs (graphical user interfaces).  These  applications long
since served  their purpose with regard to prototyping the GUI technology.
The GUI applications are not just technology prototypes however; a lot of
effort was put into the specific science applications functionality as
well.  Although the GUI technology is still being developed, we felt it was
worthwhile to release these prototype GUI applications in their current form
for trial use.

The prototype GUI applications are contained in the package GUIAPPS.  IRAF
V2.11.3 or later and the X11IRAF V1.2 (see /iraf/x11iraf on the NOAO
iraf.noao.edu ftp archive) version of xgterm is required to run the GUI
applications correctly.  Pre-built binaries for ALL platforms, test data,
tutorials, and documentation is provided for these applications to make them
as easy to use as possible.  Binaries for SunOS/Solaris and Dec Alpha Tru64
systems do not use the IRAF shared image and so should be runnable on both
IRAF V2.11 and V2.12 machines.

See the URL 
		http://iraf.noao.edu/projects/guiapps 

for  more detailed  information describing the applications provided and
how to run them.

INSTALLATION INSTRUCTIONS
-------------------------

To simply the installation as much as possible the distribution file comes
with a complete set of binaries for all IRAF V2.12 platforms, meaning there
is only a single file to download.  The package may be installed by the
IRAF site manager for system-wide use, or individual users may obtain the
package for personal use.

The  GUIAPPS package  requires  that you are also running the X11IRAF V1.2
or later release of the XGterm terminal program (because of needed bug fixes).
Users on IRAF V2.11.3 systems may still use the package but at this time
there are no prebuilt binaries available for SGI IRIX or IBM RS/6000 systems.
Please contact site support for instructions on building the package of you
would like to use this package on that system.

If you need help with these installation instructions contact [email protected]
or call the IRAF HOTLINE at 520-318-8160.


    
[1] Login in as the 'iraf' user and create a directory to contain the package
    files.  This  directory  should  be outside the standard IRAF directory
    tree, for example:
    
	% cd /iraf/extern		# go to external package dir  
        % mkdir guiapps			# create a package directory
        % cd guiapps			# go there

    For a personal installation you may wish to create the directory as
    a subdirectory of your normal IRAF login directory.


[2] The  package is distributed as a single tar archive for the sources
    and all platform binaries.  The tar file is most commonly obtained via
    anonymous ftp.  Below is an example where  the  compressed files
    have the ".Z" extension.  Files  with ".gz" can be handled in the 
    same way.
    
        % ftp iraf.noao.edu (140.252.1.1)    # ftp to archive
        login: anonymous
        password: [your email address]
        ftp> cd /iraf/extern		    # go to external packages
        ftp> get guiapps.readme		    # get these instructions
        ftp> binary			    # set binary mode
        ftp> get guiapps.tar.Z		    # get the distribution
        ftp> quit			    # quit ftp

        % uncompress guiapps.tar.Z	    # uncompress the archive.  If
					    # the file has a ".gz" extension
					    # use the "gunzip" command instead
					    # of "uncompress"
    
[3] Extract the source files from the tar archive.  At this point the
    uncompressed tar archive should be in the directory where you wish
    to unpack it.  At the unix prompt untar the file with the command:

	% tar -xvpf guiapps.tar

    Within the CL one can also use the "rtar" command to unpack the file:
    
        cl> softools
        so> rtar -xrf guiapps.tar
        so> bye
    
    On some systems, an error message will appear  ("Copy  'bin.generic'
    to  './bin  fails")  which  can  be ignored.  Sites should leave the
    symbolic link 'bin'  in  the  package  root  directory  pointing  to
    'bin.generic'  but can delete any of the bin.<arch> directories that
    won't be used. 
    
    The distribution tar file can be deleted once they  have  been  success-
    fully installed.

[4] The final step is to declare the package.  The details will vary depending
    on whether this is a site installation of the package or for personal
    use.  See below for details.

    System-Wide Installation
    ------------------------

    If  you  are  installing  the package for site use login as 'iraf' and
    edit the IRAF file defining the packages, hlib$extern.pkg.
    
        % cd $hlib
        % vi extern.pkg
    
    Define the environment variable 'guiapps' to be the pathnames to the
    GUIAPPS package root directory, pathnames must be terminated
    with a '/'.  Edit extern.pkg to include the following.
    
        reset guiapps 	   = /iraf/extern/guiapps/
        task  guiapps.pkg  = guiapps$guiapps.cl
    
    Near the end of the hlib$extern.pkg file, update the  definition  of
    helpdb  so it includes the guiapps help database, copying the syntax
    already  used  in  the  string.   Add  this  line  before  the  line 
    containing a closing quote:
    
        ,guiapps$lib/helpdb.mip\


    Personal Installation
    ---------------------

    If you are installing the package for personal use, in your login.cl or
    loginuser.cl file make the following definitions somewhere before the
    final "keep" statement:
    
        reset guiapps 	   = /home/fred/guiapps/
        task  guiapps.pkg  = guiapps$guiapps.cl
        printf ("reset helpdb=%s,guiapps$lib/helpdb.mip\nkeep\n",
            envget("helpdb")) | cl
        flpr

    Note that the path to the guiapps directory you created MUST contain
    a trailing '/' character and will vary from the example, except for
    this first line this code may be used verbatim in your login.cl to
    declare the package.


This should complete the installation.  You can  now  load  the  package
and begin testing and use.
