In which programming language is VectorSection written?
Lots. Due to the loosely-coupled architecture, any language is fair game (though choosing a language with YAML libraries makes things easier.) Given the cross-platform and open-source nature, a connector is most useful if the language has a well-supported open-source toolchain. The project maintainers speak Perl, Python, Ruby, C, C++, Fortran, Lisp, and Objective C. Java and C# might work, but you have to prove that we won’t have trouble integrating it with our test and install setups.
