This is a simple tool which can run sample tests easier.

Currenty, it support only 4 languages: c++, c, java, python. However, it coule be expand very easily and the source code is really short. I haven't added other languages just because I don't have the enviroment for verify.

This tool is only verified on Linux now, but I think it could be run on other platforms too, although it maybe need a little modify.

Again. Please feel free to fork and any suggesions are welcome. :)

You can also download the whole contest:
