As University does not allow installing any illegal software to computers, I have to try other
developement tools rather than those I used in China. Fortunately, there are many GNU
tools available, which can substutite commercial tools to some extent. As more understanding
to GNU tools, I come to know they are also very powerful in development. They can do everything
that you have to be done with commerical earlier. Some aspects are even better than commercial.
Why not have a try?
