说明：  3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的，但由于Windows系统与其他系统如Linux等的文档结构不同，项目的可移植性将会受到限制，因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的，我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本，基础代码部分不变，只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月，包括平台的移植，接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)
