If you are using git to control versions of LaTeX-files, you may want to show yourself or other users or devs the current version of the file, 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 package gives you the opportunity to do so.
