The fact that a licensing compromsise was once made in the face of an extremely poor competitor (compress not only performs badly on text, it significantly expands files gzip and bzip are perfectly capable of compressing) is largely irrelevent. The reality is that the significant improvements provided by lzma will be relegated to a niche until an implementation under a BSD-like license is available. Even RMS acknoledges this effect http://lwn.net/2001/0301/a/rms-ov-license.php3 I wouldn't necessicairly be opposed to seeing support for tar.lzma files in bsd.port.mk, but I don't think lzma has a signficant future if the licensing policy remains as is (i.e. complex and not clearly defined in the source files). -- Brooks --UugvWAfsgieZRqgk Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iD8DBQFIBW2JXY6L6fI4GtQRAtDtAJ9v0q7+k0pHoc9hocFcdn1YFDPcGACgwDZG LWJnQFgSmWIW3mmMOzw3wMs= =GrqR -----END PGP SIGNATURE----- --UugvWAfsgieZRqgk--
