The Win32 Superpack
A full description of the Win32 Supperpack can be found in the Getting Started with Win32 GrADS document. This distribution is designed as a turn key system and under normal circumstances it requires no installation whatsoever. The distribution comes in the form of a self-installing EXE file or as a single ZIP file for those users who do not have the necessary privileges to install software. The Win32 Superpack is designed to be relocatable: one can move the whole GrADS19/ directory to a CDROM or memory stick and take it on the road. This feature is particularly useful for bundling the software in DVDs and CDROMs containing large datasets.
For ease of maintenance, this Windows release contains exactly the same X Windows code base used in the Linux/Unix versions. As such, it requires an X server to be installed on Microsoft Windows. In previous releases of Win32 GrADS the installation of this X Server was a separate step. And also inconvenient, because no reliable free X Server was available. In the past few years, though, the situation has changed. The Cygwin/X Project has produced a very stable free X Server, and more recently, the Xming project is producing a fast, small, (and relocatable) X server that builds natively on Win32 without the need for the Cygwin POSIX layer (which the main GrADS binaries still use). The Xming server is currently bundled with the Win32 Superpack.
To create the illusion of simplicity, each GrADS binary fires up the Xming server whenever it starts. (However, Xming is smart enough to keep only one copy of itself running at a time.) As in previous versions of Win32 GrADS, it detects its own location and sets the relevant environment variables (GADDIR, GASCRP, GAUDXT, LD_LIBRARY_PATH, etc) automatically. As long as you keep the directory tree intact, no user intervention is necessary. However, if you want to take the PCGrADS directory tree apart you can still do so, but in this case you will need to setup the environment variables yourself. See the notes on Installing GrADS on Linux/MacOS X/Unix for a description of the environment variables involved.
