现在，我们将要深入到Subversion的使用细节当中，完成本章时，你将学会所有Subversion日常使用的命令，你将从把数据导入到Subversion开始，接着是初始化的检出(check out)，然后是做出修改并检查，你也将会学到如何在工作拷贝中获取别人的修改，检查他们，并解决所有可能发生的冲突。
Note that this chapter is not meant to be an exhaustive list of all Subversion's commands—rather, it's a conversational introduction to the most common Subversion tasks that you'll encounter. This chapter assumes that you've read and understood 第 1 章 基本概念 and are familiar with the general model of Subversion. For a complete reference of all commands, see 第 9 章 Subversion 完全参考.
在继续阅读之前，需要知道Subversion使用中最重要的命令：svn help，Subversion命令行工具是一个自文档的工具—在任何时候你可以运行svn help SUBCOMMAND来查看子命令的语法、参数以及行为方式。
$ svn help import
import: Commit an unversioned file or tree into the repository.
usage: import [PATH] URL
Recursively commit a copy of PATH to URL.
If PATH is omitted '.' is assumed.
Parent directories are created as necessary in the repository.
If PATH is a directory, the contents of the directory are added
directly under URL.
Unversionable items such as device files and pipes are ignored
if --force is specified.
Valid options:
-q [--quiet] : print nothing, or only summary information
-N [--non-recursive] : obsolete; try --depth=files or --depth=immediates
--depth ARG : limit operation by depth ARG ('empty', 'files',
'immediates', or 'infinity')
