   A few years back I did some soul searching to decide whether I should
put sometime into extending the grads scripting language. My conclusion was
that there were very well established general purpose scripting languages
already (perl, python) that would be difficult to come even close in terms
of capabilities (and size of the community supporting it). Therefore,
interfacing grads to perl and python seemed more effective, and this is how
gerl <http://opengrads.org/wiki/index.php?title=Perl_Interface_to_GrADS>and
pygrads<http://opengrads.org/wiki/index.php?title=Python_Interface_to_GrADS>came
about (and later
PHPgrads <http://opengrads.org/wiki/index.php?title=PHP_Interface_to_GrADS>and
TCLgrads <http://opengrads.org/wiki/index.php?title=TCL_Interface_to_GrADS>by
Rodrigo and Jose). These days I do my grads scripting almost
exclusively
in python.

  Perhaps Brian and Jennifer have plans for extending the scripting
language...
