Dear GrADS Users,

We have started uploading to sf.net sources and binaries for the OpenGrADS
Bundle based on COLA's *2.0.a9* release:

       https://sourceforge.net/projects/opengrads/files/


   - Look under
<goog_1598792461>*grads2/2.0.a9.oga.1<https://sourceforge.net/projects/opengrads/files/grads2/2.0.a9.oga.1/>
   *for the sources and binaries for Mac OS X, Linux and (soon) FreeBSD and
   AIX.
   - Look under
<goog_1598792465>*grads2-windows/<https://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a9.oga.1/>
   **2.0.a9.oga.1 *for the Windows binaries.

*
*
The OpenGrADS Bundle is a new way of packaging GrADS builds that is somewhat
inspired by our experience with the Win32 Superpacks. The idea is to have a
single package that require no (minimum?) configuration and that is easily
relocatable (say to a USB memory stick).  The structure of an OpenGrADS
Bundle is described here:

  http://opengrads.org/wiki/index.php?title=The_OpenGrADS_Bundle

Once you download the tarball take a look at the INSTALL file. You can
install it as a Bundle (highly recommended) or simply install the binaries
the same way you did in the past. Information about the Windows build can be
found here:


http://opengrads.org/wiki/index.php?title=Installing_GrADS_v2.0_on_Microsoft_Windows

If you would like to build it from sources notice that the OpenGrADS
Bundle 2.0.a9
requires *Supplibs v2.2.0* available from:

   https://sourceforge.net/downloads/opengrads/supplibs/2.2.0/

Building instructions:

http://opengrads.org/wiki/index.php?title=Building_the_OpenGrADS_Bundle_from_Sources


This OpenGrADS release has very minor updates in the extensions. See the
Release Notes below for more information.

   Enjoy!

                    The OpenGrADS Bundle Distribution
                    ---------------------------------

                          http://opengrads.org

                          GrADS Version 2.0.a9
                        Released 03 October 2010

This OpenGrADS version is based on COLA's 2.0.a9 release with very
minor updates in the OpenGrADS extensions.  See below for the
OpenGrADS features that extend the standard GrADS functionality
provided by COLA.

As for the new functionality in the COLA release we quote from Jennifer
Adams' announcement of GrADS v2.0.a9:

"This new release has a rather long list of new features and bug fixes;
many of these were implemented as a result of requests or reports from
users (including the recent revelation of junk bytes at the beginning
of some grib files). Thanks for your valuable input! Please see
http://iges.org/grads/changelog-2.0.txt for the complete list. I
recommend you look carefully at the change log if you are going to use
2.0.a9.

There is a new GIS interface for creating shapefiles with contours
(from gridded data) or points (from station or gridded data sets). New
commands are set gxout shp, set shp, clear shp, set shpattr, and q
shpopts. Please read the shapefiles documentation -- it will guide you
to the reference pages for all the new commands and gives some
examples (including images) of how to use this new capability.

To write out a KML file containing contours, use the new option '-ln'
to set kml. The option to create a KML file with contours does not
require any extra libraries and will always be enabled.

There are three new template substitution string options, for forecast
times expressed in minutes, hours+minutes, or
days+hours+minutes. Documentation page templates has been updated with
more detailed information.

There are two new startup options to use when invoking GrADS:
-a sets the aspect ratio of the graphics page, so you are no longer
        limited to 8.5 x 11 or 11 x 8.5.
-C enables colorization of the text in the command window
        Please see http://iges.org/grads/gadoc/gradcomdgrads.html

Files that are templated on E but not T do not have to be padded with
missing data if ensembles do not have same start/end times. This is
for binary and SDF formats, it was never necessary for grib data."

OpenGrADS Features
------------------

Several other important OpenGrADS additions are available with this version:

- this is an OpenGrADS Bundle release, a relocatable, minimum
  configuration package that has all that you need to run GrADS. See
  INSTALL for additonal information.

- preview release of the OpenGrADS Extensions; the same extensions
  available in GrADS v1.9.0-rc1 are now available with GrADS v2.0.

  Caveat: as COLA is yet to publish the official API for User Defined
          functions in GrADS v2.0 we have adopted here an API that
          is based on our work vith v1.9.0-rc1. This is a very low-level
          API that is *not* endorsed by COLA. As such, it is *not*
advisable
          that users adopt this API to write their own extensions.

- These extensions are still being fully tested. Please report any problems
  you encounter. Use them at your own risk.

- The following extensions are included: see below.
