You are about to install GSSTK software.  (GSSTK is a rewrite of the 
original DOS GSSEARCH software.)  The GSSTK software uses a Tcl/Tk 
(Tool Command Language/Tool Kit) script to provide the graphical user 
interface (GUI), and a C language executable running in the background 
to do the data search, retrieval, and manipulation.  Using Tcl/Tk 
allows the same GUI script to run on Windows 95, 98, and NT, as well 
as MacOs, Linux and Unix systems.  

In order to use the GSSTK software, GSSTK.EXE, GSSTK.TCL and the Tcl/Tk 
software must be installed on your computer.  This will be done 
automatically as part of the GSSTK installation.  Simply run winsetup.exe 
from the CD.  A GSSTK directory will be created for the software, and a
WIGLO directory for the database working directory.  A shortcut to the 
database will also be installed on the Desktop.  Do not edit GSSTK.TCL 
in any way.  If it becomes corrupted, simply copy it from the source 
directory on the CD.
