       <p>If any of the things listed to include in the tarball is a directory, tar will automatically recursively add everything inside the directory too.  This is part of the reason for the convention of using a single wrapper directory, as then that is the only thing you have to explicitly list when creating the tarball.</p>

       <p>There are many more options to tar, which are detailed in tar's documentation.  The ones mentioned here, though, are the most commonly used ones. For further reading:</p>
