+information about the author and last edited date.  All packages for Git known
+make that kind of information available for the whole repository.  But
+sometimes you have a lot of files within the same repository in different
+versions, from different authors etc.  Perhaps you also split up a big project
+in small files and want to show within the document who had edited what.  This
