Another option is to do it the way the Apple MacOS "resource forks" are stored in .zip files. This is done as follows: If a file foo/bar.suf has a "resource fork" (usually up to 512 bytes of binary data), then the zip contains two files foo/bar.suf __APPLE_RESOURCES__/foo/bar.suf This way, if the tarball is unpacked on a non-MacOS system and re-packed, the added information will not be lost. And additionally, this added information does not hurt: it is in a separate directory that can easily be removed. Bruno
