Chances are the pkg_tools can safely ignore this command and proceed with what it knows about. In other words, extensions to the command set should not be fatal; revisions to the command set which break backwards compatibility should be fatal (and this is achieved by bumping the version) Kris --a8Wt8u1KmwUX3Y2C Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (FreeBSD) iD8DBQE9cmVXWry0BWjoQKURAiEMAKCvO3fDjbMvigB8nmTQaShqlreTzgCePnUk sVm/sE2eUh1ZhBlbWzrWgUs= =pJFd -----END PGP SIGNATURE----- --a8Wt8u1KmwUX3Y2C-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
