The file regrid.tar contains the source, makefile, docs and
user-defined function table for the GrADS user-defined function
regrid.  Be sure to ftp regrid.tar in binary mode because the
distribution contains a Wordperfect file.  Also, regrid requires
that you run V1.4+ of GrADS.  You can get the latest version by
anonymous ftp from

cola1.umd.edu


Installation steps:

1)	Decide where to install regrid.  

The makefile and these instruction will assume you have installed
GrADS in the "standard" directories (/usr/local/bin for
executables and /usr/local/lib/grads for docs and data files).
You will probably have to be super user to do this...

2)	Copy regrid.tar to /usr/local/lib/grads

3)	tar -xvf regrid.tar

makes the directory /usr/local/lib/grads/udf and
/usr/local/lib/grads/udf/regrid

4)	cd udf

go the the directory which contains the file udft.regrid.  This
is the file GrADS looks to when locating the user-defined
function executable.

5)	cd regrid 

go down to the regrid directory.  

6)	make -f makefile.regrid

makes the executable file regrid.exe in /usr/local/lib/grads/udf

7)	consult the documentation files in /usr/local/lib/grads/udf/regrid

regrid.wp is a Wordperfect V5.1 version of the documentaion and
regrid.txt is the ASCII version.  The last step in using regrid
is to set the shell environment variable GAUDFT.  For the assumed
file locations and names, add

setenv GAUDFT /usr/local/lib/grads/udf/udft.regrid

to your .cshrc/.login file.


GOOD LUCK and please contact me email if you should have any
question regarding the installation and use of regrid....
