 Licensing
 ---------
 
-ZFS is licensed under the Common Development and Distribution License
-(`CDDL <http://hub.opensolaris.org/bin/view/Main/opensolaris_license>`__),
-and the Linux kernel is licensed under the GNU General Public License
-Version 2 (`GPLv2 <http://www.gnu.org/licenses/gpl2.html>`__). While
-both are free open source licenses they are restrictive licenses. The
-combination of them causes problems because it prevents using pieces of
-code exclusively available under one license with pieces of code
-exclusively available under the other in the same binary. In the case of
-the kernel, this prevents us from distributing ZFS on Linux as part of
-the kernel binary. However, there is nothing in either license that
-prevents distributing it in the form of a binary module or in the form
-of source code.
