【有关Recursive与 Build tree】(来源于VSS帮助)
Recursive (project-level Get only)
Gets a project, all the files in the project, and its subprojects. Each file in a subproject is copied into its own working folder, which can be a folder anywhere
on your computer or an accessible remote computer. To override the working folder
settings, and create a file structure that mirrors the VSS project structure, use
the Build Tree option.
简言之:若一个目录中的子目录设定了另外的工作目录,则recursive保证对服务器上各子目录
文件进行操作.build tree则强制将服务器上的各目录原封不动的映射到本地目录中,而不管其
中子目录被设定到其它工作目录.
