snom Vision User Manual Appendix 3 - GNU General Public License
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section
1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that
in whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third parties under
the terms of this License.
c) If the modified program normally reads commands
interactively when run, you must cause it, when started running for
such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a warranty)
and that users may redistribute the program under these conditions,
and telling the user how to view a copy of this License. (Exception:
if the Program itself is interactive but does not normally print such an
announcement, your work based on the Program is not required to print
an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be
reasonably considered independent and separate works in themselves,
then this License, and its terms, do not apply to those sections when
you distribute them as separate works. But when you distribute
the same sections as part of a whole which is a work based on the
Program, the distribution of the whole must be on the terms of this
License, whose permissions for other licensees extend to the entire
whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control
the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume
of a storage or distribution medium does not bring the other work under
the scope of this License.

. You may copy and distribute the Program (or a work based
on it, under Section 2) in object code or executable form under the
terms of Sections 1 and 2 above provided that you also do one of the
following:
a)
Accompany it with the complete corresponding machine-
readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software
interchange; or,
b) Accompany it with a written offer, valid for at least three years,
to give any third party, for a charge no more than your cost of physically
performing source distribution, a complete machine-readable copy
of the corresponding source code, to be distributed under the terms
of Sections 1 and 2 above on a medium customarily used for software
interchange; or,
c) Accompany it with the information you received as to the
offer to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you received the
program in object code or executable form with such an offer, in accord
with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to control
compilation and installation of the executable. However, as a special
exception, the source code distributed need not include anything that
is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
If distribution of executable or object code is made by offering access
to copy from a designated place, then offering equivalent access to
copy the source code from the same place counts as distribution of the
source code, even though third parties are not compelled to copy the
source along with the object code.
4. You may not copy, modify, sublicense, or distribute the
Program except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is void,
and will automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this License
will not have their licenses terminated so long as such parties remain in
full compliance.
5. You are not required to accept this License, since you
have not signed it. However, nothing else grants you permission to
modify or distribute the Program or its derivative works. These actions
are prohibited by law if you do not accept this License. Therefore,
by modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying the
Program or works based on it.
6. Each time you redistribute the Program (or any work based
on the Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further restrictions
on the recipients‘ exercise of the rights granted herein. You are not
responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot distribute
so as to satisfy simultaneously your obligations under this License and
any other pertinent obligations, then as a consequence you may not
distribute the Program at all. For example, if a patent license would
not permit royalty-free redistribution of the Program by all those who
receive copies directly or indirectly through you, then the only way you
could satisfy both it and this License would be to refrain entirely from
distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any such
claims; this section has the sole purpose of protecting the integrity of
the free software distribution system, which is implemented by public
license practices. Many people have made generous contributions
to the wide range of software distributed through that system in
reliance on consistent application of that system; it is up to the
author/donor to decide if he or she is willing to distribute software
through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be
a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted
in certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among countries not
thus excluded. In such case, this License incorporates the limitation as
if written in the body of this License.
