+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
