For Approval: Common Development and Distribution License (CDDL)

Please consider the attached license (text form attached) for OSI review and 
approval.  It is called the Common Development and Distribution License (CDDL).
	http://www.sun.com/cddl/

CDDL is derived from MPL1.1.  High-level and detailed descriptions of what has 
been changed from MPL are available at:

Redline/diffs between CDDL and MPL can be found at:

As required, here is an explanation of how software distributed under this 
license can be used in conjunction with software distributed under other open 
source licenses:

The CDDL is similar to the MPL and its derivative licenses (CPL, SPL,
etc.) in terms of combination with software distributed under other
licenses.  As with the MPL, files made available under the CDDL can be
linked together with files made available under another license, as
long as the other license does not prevent such linkage.  This means
that (for example) files licensed under the CDDL can be linked
together with files licensed under the MPL, SPL, CPL (or other
licenses that allow files under different licenses to be linked
together) as well as with code released under "academic" licenses such
as BSD, AFL, Apache, and X11.  In addition, source code licensed under
the CDDL can be combined in the same file with code licensed under an
academic license, as long as the resulting source file is distributed
under the CDDL.

Note that if files under different licenses are statically linked and
the resulting binary is distributed, then the binary license must meet
the terms of both licenses.  For example, the source for any
modifications to files licensed under CDDL must be distributed even if
those files are linked with files available under a license without
such a requirement.

Like the MPL, the CDDL is not expected to be compatible with the GPL,
since it contains requirements that are not in the GPL (for example,
the "patent peace" provision in section 6).  Thus, it is likely that
files released under the CDDL will not be able to be combined with
files released under the GPL to create a larger program.
