[Nek5000-users] Using postx

[nek5000-users at lists.mcs.anl.gov]

Hi Rich,

Great question -- I'm checking with Hank Childs
to see if 2.4.0 is up to date with the Nek5000 reader.

Also, I just noticed that the script we normally use
to generate a meta-data file is not in the repo.  It
should be shortly -- it's called "nekvis".  I usually
use it (on linux platforms) by simply typing

   nekvis

or

nekvis session

where session is the name of the .rea file.  This script
creates the metadata file and then launches VisIt. I'm attaching 
the script that I use here, but Katie is putting the latest 
into the repo.
