[Scilab-users] question on graphic children order

[Federico Miyara]

Samuel,

I would like to contribute somehow, but for the moment I don't know 
anything about Java and very little about C or C++. I could test code if 
it is in a version ready to install (I don't know how to compile) and if 
there is some protocol or guidelines to how to perform tests.

I find more likely for me to contribute Scilab functions written using 
the available functions and operators, or try to improve help pages.

Regards,

Federico
