[gradsusr] A replacement script for gxyat in OpenGrADS 2.1

[Arlindo da Silva]

All,

   As you may have noticed, gxyat wa not included in the latest OpenGrADS
Bundle release 2.1.a2.  Gxyat had the same fate of gxtran, gxeps, etc, and
was retired. To minimize the amount of work migrating from OpenGrADS 2.0 to
2.1, you can use this gxyat replacement script:

    gxyat.gs
<http://sourceforge.net/projects/opengrads/files/grads2/2.1.a2.oga.1/gxyat.gs/download>

This is a simple wrapper for *gxprint* using a *gxyat* compatible syntax.
 Notice that gxyat options that are not supported by gxprint are simply
ignored. Also,

ga-> gxyat test.png

would produce an image with a WHITE background, rather than the gxprint
BLACK background. Use the -r option to obtain a BLACK background. Here, is
the man page for the script:

SYNOPSIS


      gxyat OPTIONS [filename]


DESCRIPTION

      Simple wrapper for gxprint using a gxyat compatible syntax.

      Notice that file name can also be specified with -o option

      Please use gxprint directly if you can.


      OPTIONS

     +a           (ignored)

     -f           (ignored)

     -h           prints this manual page

     -i fname     (ignored)

     -o fname     output file name/pipe command; the file name extension

                  determines the desired format, e.g.,

                  png     Portable Network Graphics

                  ps      Postscript

                  pdf     Portable Document Format (PDF)

                  svg     Scalable Vector Graphics

     -r           Black background (default is white, unlike gxprint)

     -v           Verbose.

     -x m         number of horizontal pixels

     -y n         number of vertical pixels

     -w s         (ignored)

     Enter "gxyat -h" for additional information

    Let me know if you have questions.
