hello_world

This is just a guide product to get familiar with the system I'm doing this for my ICS presentation. But I hope that I will have more future usage of this strong tool. well, actually I begin to feel the interesting aspects of giving a presentation. It actually forces me to learn something really new and beyond the textbooks. And it also really enhance my ablity to understand and try to use new things. It also improves my ablity to organise and give a speech. The only disadvantage may be that the process is time-consuming.
