svnlook is a command-line utility for examining different aspects of a Subversion repository. It does not make any changes to the repository—it's just used for “peeking.” svnlook is typically used by the repository hooks, but a repository administrator might find it useful for diagnostic purposes.
Options in svnlook are global, just like in svn and svnadmin; however, most options apply only to one subcommand since the functionality of svnlook is (intentionally) limited in scope.
Causes svnlook changed to show detailed copy source information.
Prevents svnlook diff from printing differences for deleted files. The default behavior when a file is deleted in a transaction/revision is to print the same differences that you would see if you had left the file but removed all the content.
Prevents svnlook diff from printing differences for added files. The default behavior when you add a file is to print the same differences that you would see if you had added the entire contents of an existing (empty) file.
