stdout.
--force-uuid --ignore-uuid --parent-dir --quiet (-q) --use-post-commit-hook --use-pre-commit-hook
这里显示了加载一个备份文件到版本库(当然，使用svnadmin dump)：
$ svnadmin load /var/svn/restored < repos-backup
<<< Started new txn, based on original revision 1
* adding path : test ... done.
* adding path : test/a ... done.
…
或者你希望加载到一个子目录：
$ svnadmin load --parent-dir new/subdir/for/project \
/var/svn/restored < repos-backup
<<< Started new txn, based on original revision 1
* adding path : test ... done.
* adding path : test/a ... done.
…
