Re: [Opengrads-devel] OpenGrADS development - PHP interface

[Luiz R. T. <lui...@gm...>]

Ok, Arlindo

I'll work on it using "display => gxyat => svg file => php" and once its
stable I'll try using "display => php pipe"

I'll keep on writing the php code and, as soon as I have the permission,
I'll place it in the CVS.

Peace
