Burp 是一个用来备份和恢复数据的程序，使用 libsync 库.
* Fix some Mac compilation warnings. * Fix a bug where specifying an alternative restore directory with a trailing slash would not work. * Set REMOTE_ADDR and REMOTE_PORT environment variables. * Force the user spell out '-a delete', to avoid confusion with the future 'diff/long diff' options. Prevent old clients from deleting, to prevent potential accidents. * Fix a problem where interrupting the client during a list could leave the server child process hanging indefinitely.
