说明：  Pragmatic Version Control use git 的英文原版。Git是今年兴起的分布式版本控制工具，跨平台轻量级但是功能毫不逊色于clearcase, SVN这样传统版本控制系统，许多linux操作系统和android的开发小组都在使用git。本书是目前我能找到的最好的入门教材，适合于开发人员和项目管理人员。
("Pragmatic Version Control use git" the English original. those years, git becames a new star of distributed version control tool, cross-platform features lightweight, but no less in the clearcase, SVN version control system so traditional, and many linux operating systems and android development team are using git. This book is the best I can find for new comers, suitable for developers and project managers.)
