所有的程序开发手册都包含了各种规则。一些习惯自由程序人员可能对这些规则很不适应，但是在多个开发人员共同写作的情况下，这些规则是必需的。这不仅仅是为了开发效率来考虑，而且也是为了后期维护考虑。定义这个规范的目的是让项目中所有的文档都看起来像一个人写的，增加可读性，减少项目组中因为换人而带来的损失。（这些规范并不是一定要绝对遵守，但是一定要让程序有良好的可读性）。-Development of all manual contains a variety of rules. Some may be accustomed to the free program is not suited to these rules, but common in a number of developers writing, these rules are necessary. This is not just to develop the efficiency considerations, but also to consider the latter to maintain. The purpose of the definition of this specification is to project all of the documents look like one person wrote to increase readability and reduce the project team due to losses brought about by change. (These norms do not have to fully comply with, but the procedure must allow good readability).
