<para>写代码是一个工程，程序设计是一种艺术；如果程序员只注重代码，那就象盖房子时的砌砖匠，只知道照图施工而已。世界那么多令人叹为观止的美丽建筑物，那是设计家的艺术杰作，而不是砌砖匠的艺术杰作。

Knowledge Intergration is Supper Skill
        What I hear I forget,
                What I see I remember,
                        What I do I understand.

<listitem>
<para>whatever style you use, please use it consistently, since a mixture of styles within one program tends to look ugly. If you are contributing changes to an existing program, please follow the style of that program.
