Linden Research, Inc. ("Linden Lab") Viewer FLOSS License Exception v0.5
|
|
|
|
The Linden Lab Exception for Free/Libre and Open Source Software-only
|
|
Applications Using Linden Lab Viewer Software (the "FLOSS Exception").
|
|
|
|
Exception Intent
|
|
|
|
Linden Lab is releasing the source code for certain software that
|
|
enables users to view or otherwise access the Second Life virtual
|
|
world environment (the "Viewer Software"), under version 2 of the GNU
|
|
General Public License (the "GPL"). The creation or distribution of
|
|
works based on the Program (as defined under the GPL) of the Viewer
|
|
Software may require the use of certain Free/Libre and Open Source
|
|
Software ("FLOSS") works that are subject to license agreements not
|
|
compatible with re-licensing under the GPL. Because we want to allow
|
|
the Viewer Software to be distributed with these FLOSS works, this
|
|
FLOSS Exception following exception applies subject to the terms and
|
|
conditions below.
|
|
|
|
Legal Terms and Conditions
|
|
|
|
As a special exception to the terms and conditions of version 2.0 of
|
|
the GPL:
|
|
|
|
You are free to distribute a work based on the Program that is formed
|
|
entirely from the Viewer Software (and any modifications thereof) and
|
|
one or more works that are independent and separate works not derived
|
|
from the Viewer Software, and are licensed under one or more of the
|
|
licenses listed below in section 1 (each, a "FLOSS Work") , as long
|
|
as:
|
|
|
|
A. You obey the GPL in all respects for the Viewer Software and any
|
|
work based on the Program, except for the FLOSS Works, for which
|
|
you must comply with B below,
|
|
|
|
B. all FLOSS Works,
|
|
|
|
i. are distributed subject to one of the FLOSS licenses
|
|
listed below, and
|
|
|
|
ii. the object code or executable form of the FLOSS Works are
|
|
accompanied by the complete corresponding
|
|
machine-readable source code for those FLOSS Works on the
|
|
same medium and under the same FLOSS license as the
|
|
corresponding object code or executable forms thereof,
|
|
and
|
|
|
|
C. any works that are aggregated with the Viewer Software or a work
|
|
based on the Program on a volume of a storage or distribution
|
|
medium in accordance with the GPL, and are not licensed under
|
|
the FLOSS licenses listed below, are independent and separate
|
|
works in themselves which are not derivatives of either the
|
|
Viewer Software, a work based on the Program or a FLOSS Work.
|
|
|
|
If the above conditions are not met, then the Viewer Software may only
|
|
be copied, modified, distributed or used under the terms and
|
|
conditions of the GPL or another valid licensing option from Linden
|
|
Lab.

3. Applicability
|
|
|
|
This FLOSS Exception applies to all Viewer Software files that contain
|
|
a notice placed by Linden Lab saying that the Viewer Software may be
|
|
distributed under the terms of this FLOSS Exception. If you create or
|
|
distribute a work which is a work based on the Program for the Viewer
|
|
Software and any other work licensed under the GPL, then this FLOSS
|
|
Exception is not available for that work; thus, you must remove the
|
|
FLOSS Exception notice from that work and comply with the GPL in all
|
|
respects, including by retaining all GPL notices. You may choose to
|
|
redistribute a copy of the Viewer Software exclusively under the terms
|
|
of the GPL by removing the FLOSS Exception notice from that copy of
|
|
the Viewer Software, provided that the copy has never been modified by
|
|
you or any third party.
