-The tar file for version @var{m}.@var{n} of program @code{foo} should be

+All packages should provide tar files for the distribution of their
+releases. The tar file for version @var{m}.@var{n} of program
+@code{foo} should be named @file{foo-@var{m}.@var{n}.tar}. It should
+unpack into a subdirectory named @file{foo-@var{m}.@var{n}}. Tar
+files should not unpack into files in the current directory, because
+this is inconvenient if the user happens to unpack into a directory
+with other files in it.
