svn export — 导出一个干净的目录树。
The first form exports a clean directory tree from the
            repository specified by URL—at revision
            REV if it is given, otherwise
            at HEAD, into
            PATH.  If
            PATH is omitted, the last
            component of the URL is used
            for the local directory name.
从工作拷贝导出干净目录树的第二种形式是指定PATH1到PATH2,所有的本地修改将会保留,但是不再版本控制下的文件不会拷贝。
--revision (-r) REV --quiet (-q) --force --username USER --password PASS --no-auth-cache --non-interactive --depth ARG --config-dir DIR --native-eol EOL --ignore-externals
从你的工作拷贝导出(不会打印每一个文件和目录):
$ svn export a-wc my-export Export complete.
从版本库导出目录(打印所有的文件和目录):
$ svn export file:///var/svn/repos my-export A my-export/test A my-export/quiz … Exported revision 15.
When rolling operating system-specific release
            packages, it can be useful to export a tree that uses a
            specific EOL character for line endings.  The
            --native-eol option will do this, but it
            affects only files that have svn:eol-style =
            native properties attached to them.  For
            example, to export a tree with all CRLF line endings
            (possibly for a Windows .zip file
            distribution):
$ svn export file:///var/svn/repos my-export --native-eol CRLF A my-export/test A my-export/quiz … Exported revision 15.
You can specify LR,
            CR, or CRLF as a
            line-ending type with the --native-eol
            option.
