This README explains briefly how to install
opendx-4.3.0-cygwin-1.3.22.tar.gz binaries.

1) Download and install the latest version of Cygwin (used dll
   1.3.22). You can get it from http://cygwin.com

2) Download opendx-4.3.0-cygwin-4.3.0.tar.gz to c:\temp

3) Start a cygwin bash shell (double-click on cygwin icon?)

4) execute exactly the following commands in the bash shell 

	   cd /

	   tar zxvf /cygdrive/c/temp/opendx-4.3.0-cygwin-1.3.22.tar.gz

   this command will extract the necessary binaries and examples in
   /usr/local/bin and /usr/local/dx.  

5) To use OpenDX, you need to start the xfree server.  At this point,
   I'm not an expert, so I execute at the bash shell the command:

	   startxwin.sh

   and in this window, you can type "dx" with the options as
   mentioned in the manual.

6) NetCDF, CDF, HDF support are not included.

COMPILATION NOTES.

While compiling the code, no big problems where found. After
"./configure", "make" with a small problem:

* while compiling src/exec/libdx/zclipQ.c, the compiler (gcc-3.2) got
a lot of time (bug in gcc-3.2?), so I changed the optimization from
-O2 to -O0 for this file, and everything else was fine.

so after compiling this file, I make "make" and "make install"
