modsIDL v1.0 Update
2019 Feb 10 

Overview

If you already have a working Linux or OSX version of the modsIDL pipeline
from before this date, you can update to the binocular version by just
loading the new code specific to MODS instead of having to re-install the
entire xidl snapshot (~290k vs ~250M for the whole thing).

This distribution will install the core code for the modsIDL v1.0 binocular 
reduction update.


Instructions:

1) Download the tar file in a safe place, say
    
   /path/to/tarball/modsIDL.justMODS.v1.0.tgz

2) cd to your modsIDL installation, for example:

   % cd <wherever>/xidl/Spec/Longslit/pro/LBT/

   and make sure that when you type ls you see the MODS folder like this:

   % ls
   LUCIFER/ MODS/

3) Make a copy the old MODS folder as a backup in case you need to roll back

   % tar cvzf oldMODS.tgz MODS

4) Replace it with the new MODS folder contents:

   % tar xvzpf /path/to/tarball/modsIDL.justMODS.v1.0.tgz

   and say "yes" if it asks to overwrite any existing files

Done.

If bad things happen (they shouldn't, but just in case), revert to the
old MODS folder and let us know what the problem is.
