Pedro,
   You are in. For the bulk of the OpenGrADS documentation go to

           http://opengrads.org

and click on documentation on the left. You should receive the wiki password
on a separate e-mail; user name is same as on sf.net.

To check out bleeding edge sources:

export CVS_RSH=ssh

cvs -z3 -d:ext:ped...@op...:/cvsroot/opengrads
co
-r GRADS2_DEV_BRANCH grads

Look under grads/src for C and java sources.  Are you familiar with CVS? If
so, please check in your mods to the Java sources. You will need additional
info in order to build grads.class (which derives from C sources using the
NestedVM toolchain); in particular the supplibs for NestedVM and a patched
NestedVM installation (mostly additions to .h files).  What is your
development platform? If using Mac OS 10.5 I can share my binaries with you.
 Otherwise, build the NestedVM toolchain from:

            http://nestedvm.ibex.org/

However, as you have already figured out,  the JGrads.class can be developed
separately from the grads.class.

    Arlindo
