NGUI - Phil Daly (pnd@noao.edu)
===============================

0. Pre-requisities: Linux or Mac OS X, tcl/tk

1. Unpack the tar-ball to a suitable place (e.g. $HOME):

 % mkdir $HOME/ngui $HOME/exec
 % cp 20111115.tgz $HOME/ngui/
 % cd $HOME/ngui
 % gzip -cd 20111115.tgz | tar xvf -

2. Edit line 15 of etc/ngui.cshrc file to make NGUI_HOME reflect your
  location. Make sure you have read+write access the $NGUI_HOME/src/ngui.

3. Source the file and build:

 % source $HOME/ngui/etc/ngui.cshrc
 % rehash
 % cd $NGUI_HOME
 % make everything

4. Remove any current tclIndex file:

 % rm $NGUI_HOME/src/ngui/tclIndex

5. Try the package:

 % rehash
 % ngui &

If you wish to run the software for the WIYN 0.9m, execute:

 % setenv NGUI_TELESCOPE kpno_36
 % ngui &

Put the following line(s) in your ~/.cshrc:

 source $HOME/ngui/etc/ngui.cshrc
 rehash

Your scripts will appear in $NGUI_EXEC = $HOME/exec. If you wish your
script to appear elsewhere (for example, /tmp) replace step 5 with:

 % setenv NGUI_EXEC /tmp
 % rehash
 % ngui &

NB: The default filters file is for exampl/experiment only and may not
reflect the filters in use for your observing run. You may edit the file
$NGUI_CFG/mosaic_filters.conf as you see fit but you must preserve the
format!
