SVN provides several commands that allow you to get information about the files in the repository:
When you move or copy a file, using the commands above, SVN keeps track of its original history. So, by default, if you svn copy a file and then svn log the new file, you'll see the file's revision history all the way back to the point at which it was first added to the repository. (SVN will follow an arbitrary number of copies back.)
