If the Smart Switch doesn't respond when pressing the physical switch:
• Make sure
that you restore power to the Smart Switch at the circuit breaker.
Make sure the SmartSwitch is wired correctly. Please
consult with a qualified
electrician.
2. What should I do when the Smart Switch doesn't respond to commands or
scheduled automations?
Check your network connectivity .
Check
if the Wi-Fi status LED on the Smart Switch is blinking amber and
green.
If so, reconnect the Smart Switch to your Wi-Fi network.
Do
not use a metal faceplate with the Smart Switch to prevent Wi-Fi signal
interference.
Power cycle
your router and/or reboot the Smart Switch by pressing the
RESTART button underneath the switch .
Factory reset the Smart Switch by pressing and holding the
RESET button .
You'll need to configure the SmartSwitch again.

Everyone
is
permitted
to
copy and distribute verbatim copies
of
this
license document,
but
changing
it
is
not
allowed.
Preamble
The license agreements
of
most software companies
try
to
keep users
at
the
mercy
of
those companies.
By
contrast, our General Public
License
is
intended
to
guarantee your freedom
to
share and change
free software--to make sure the software
is
free for all its
users.
The
General Public License applies
to
the
Free Software Foundation's
software and
to
anyotherprogram whose authors
commit
to
using it.
You
can
use
it
for
yourprograms,too.
When we speak
of
free software,
we
are referring
to
freedom,
not
price. Specifically,
the
General Public License
is
designed
to
make
sure
that
you have
the
freedom
to
give away
or
sell copies
of
free
software,
that
you receive source code
or
can
get
it
if
you want it,
that
you
can
change the software
or
use pieces
of
it
in new free programs;
and
that
you know you can
do
these things.
To
protect
your
rights,
we
need
to
make restrictions
that
forbid
anyone
to
denyyou these rights
or
to
ask
you
to
surrender the rights.
These restrictions translate
to
certain responsibilities
for
you
if
you
distributecopies
of
the software,
or
if
you modify it.
For example,
if
you distribute copies
of
a such a program,
whether
gratis
or
for a
fee,
you must give
the
recipients all the rights
that
you
have.
You
must make sure
that
they, too, receive or
can
get
the source
code. And you musttell
them
their rights.
We
protect your rights
with
two
steps:
(1)
copyright the software, and
(2)
offer you this license which gives you legal permission
to
copy,
distributeand/or modifythe software.
Also,
for each author's protection and ours, we want
to
make certain
that everyone understands that there
is
no
warranty for
th
isfree soft-
ware.
Ifthe software
is
modified
by
someone else and passed
on
, we
want its recipients
to
know that what they have
is
not
the original,
so
thatany problems introduced byotherswill
not
reflect on the original
authors'reputations.
The precise terms and conditions for copying, distribution and modi-
fication follow.

This License Agreement applies
to
any program
or
other
work
which contains a notice placed by the copyright holder saying it
may be distributed undertheterms
of
this General Public License.
The "Program'; below, refers
to
any such program
or
work, and a
"work based
on
the
Program" means either the Program
or
any
work containing the Program
or
a portion
of
it, either verbatim
or
with modifications.
Each
licensee
is
addressed
as
"you
".
1.
You
may copy and distribute verbatim copies
of
the
Program's
source code
as
you receive it,
in
any
medium,
provided
that
you conspicuously and
app
ropriately publish on each copy an
appropriate
copyright
notice and disclaimer
of
warranty; keep
intact all the notices that refer
to
this General Public License and
to
the absence
of
any warranty; and give any other recipients
of
the Program a copy
of
this General Public License along
with
the
Program.

2.
You
may
modify
your
copy
or
copies
of
the
Pr
ogram

cause
the
modified files
to
carry
prominent
notices stating
thatyou changed
the

or
any
part
thereof, either
with
or
without
modifications,
to
be licensed at
no charge
to
all third parties under
the
terms
of
this General
Public License (except
that
you may choose
to
grantwarranty
protection
to
some orall third parties, atyouroption).
c)
If
the modified program normally reads commands interac-
tively when run, you must cause it, when started running
for
such interactive
use
in
the
simplest and most usual 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

transferring a
copy, and you may at your
option
offer warranty protection
in exchange for afee.
e)
Mere aggregation
of
another
independent
work
with
the
Program (or its derivative) on a volume
of
a storage
or
dis-
tribution
medium
does
not
bring the
other
work
under the
scope
of
these terms.
3.
You
may copy and distribute
the
Program (or a
portion
or
deriv-
ative
of
it, under Paragraph
2)
in object code
or
executable form
under the terms
of
Paragraphs 1 and 2 above provided
that
you
also
do
one
of
the
following:
a)
accompany
it
with
the
complete
corresponding
ma
-
chine-readable source code, which mustbe distributed under
the terms
of
Paragraphs 1and 2 above; or,
b)
accompany
it
with
awritten offer, valid
for
atleast three
years,
to
give any third party free (except
for
a nominal charge for
the
cost
of
distribution) a complete machine-readable copy
of
the
corresponding source code,
to
be
distributed
under
the terms
of
Paragraphs 1and 2 above; or,
c)
accompany
it
with
the information you received
as
to
where
the
corresponding source code may be obtained. (This al-
ternative is allowed only for noncommercial distribution and
only
if
you received the program in object code
or
executable
form alone.)
Source code
for
a
work
means
the
preferred
form
of
the
work
for
making modifications
to
it. For an executable file, complete
source code means all
the
source code for all modules
it
contains;
but,
as
a special exception,
it
need
not
include source code for
modules which are standard libraries
that
accompany
the
oper-
ating system
on
which
the
executable file runs, or
for
standard
header files
or
definitions files
that
accompany
that
operating
system.
4.
You
may
not
copy, modify, sublicense, distribute
or
transfer
the
Program except
as
expressly provided under this General Public
License. Any
attempt
otherwise
to
copy,
modify,
sublicense,
distribute
or
transfer
the
Program
is
void, and will automatically
terminate
your
rights
to
use
the
Program
under
this
License.
However,
parties
who
have received copies,
or
rights
to
use
copies, from you under this General Public License will
not
have
their licenses terminated so
long
as
such parties remain in full
compliance.
5.
By
copying, distributing
or
modifying
the
Program (or any work
based
on
the
Program) you
indicate
your
acceptance
of
this
license
to
do
so,
and all itsterms and conditions.

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 grant-
ed herein.
7. The Free
Software Foundation may publish revised and/or new
versions of the General Public License from time to time. Such
new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each
version is given a distinguishing version number. If the
Program specifies a version number of the license which applies
to it and "any later version'; you have the option of following the
terms and conditions either of that version or of any later version
published by the Free Software Foundation. If the Program does
not specify a version number of the license, you may choose any
version ever published by the Free Software Foundation.
8.
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted
by the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our deci-
sion will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the shar-
ing and reuse of software generally.
NO WARRANTY
9.
BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED
BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRIT-
ING
THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE
THE PROGRAM"AS IS"WITHOUTWARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE
OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION.
10. IN NO
EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED
TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, IN-
CLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUEN-
TIAL DAMAGES ARISING OUT
OF THE USE OR INABILITY TO USE
THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED
BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO
OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under
these terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it
does.>

Everyone
is
permitted
to
copy and distribute verbatim copies
of
this
license document,
but
changing
it
is
not
allowed.
Preamble
The licenses
for
most
software
are
designed
to
take
away
your
freedom
to
share and change it.
By
contrast, the
GNU
General Public
License
is
intended
to
guarantee your freedom
to
share and change
free software--to make sure
the
software
is
free for all its users.This
General Public License applies
to
most
of
the
Free
Software Founda-
tion's software and
to
any other program whose authors
commit
to
using it. (Some other
Free
Software Foundation software
is
covered
by the
GNU
Lesser
General Public License instead.)
You
can
apply
it
to
your programs, too.
When we speak
of
free software, we are referring
to
freedom,
not
price.Our General Public Licenses are designed
to
make sure that you
have
the
freedom
to
distribute copies
of
free software (and charge
for this service
if
you wish),
that
you receive source code
or
can
get
it
if
you want it,
that
you
can
change the software or
use
pieces
of
it
in
newfree programs; and
that
you knowyou can
do
these things.
To
protect
your
rights, we need
to
make restrictions
that
forbid
anyone
to
deny you these rights or
to
ask
you
to
surrender the rights.
These restrictions translate
to
certain responsibilities for you
if
you
distribute copies
of
the software,
or
if
you modifyit.
For example,
if
you
distribute
copies
of
such a program,
whether
gratis
or
for a
fee,
you must give the recipients all the rights that you
have.
You
must make sure
that
they, too, receive
or
can
get
the source
code. And you must showthem these terms
so
they know their rights.
We
protect your rights wi
th
two
steps: (1) copyri
ght
the
software, and
(2)
offer you this license which gives you legal permission
to
copy,
distribute and/ormodifythe software.
Also,
for each author's protection and ours, we want
to
make certain
thateveryone understands that there isno warranty for this free soft-
ware.
If
the software
is
modified by someone else and passed on, we
want its recipients
to
know
that
what
they
have
is
not
the original,
so
thatany problems introduced by others will
not
reflect on the original
authors'reputations.
Finally, any free
program
is
threatened
constant
ly
by
softwa
re
patents.
We
wish
to
avoid
the
danger
that
redistributors
of
a free
program will individually obtain patent licenses, in effect making the
program proprietary.
To
prevent this, we have made
it
clear that any
patent must be licensed for everyone'sfree
use
or
not
licensed at
al
l.
The
precise terms and conditions
fo
r copying, distribution and
mod
i-
fication follow.

0.
This
License applies
to
any program
or
otherworkwhich contai
ns
a notice placed by the copyright holder saying
it
may be distrib-
uted undertheterms
of
this General Public License.The"Program':
below, refers
to
any such program
or
wo
rk, and a "
wo
rk based
on
the
Program" means
either
the
Progr
am
or
any
de
rivative
work under copyright law:
that
is
to
say
, a work containing the
Program or a portion
of
it, either verbatim
or
with
modifications
and/or translated into another language. (Hereinafter,translation
is
included
without
limitation
in
the
term
"
modi
fication"
.)
Each
licensee
is
addressed
as
"you':
Activities
other
than
copying, distribution and modification are

not
covered by this License; they are outside its scope. The act
of
running
the
Program
is
not
restricted, and
the
output
from
the
Program
is
covered only
if
its contents constitute a
work
based
on
the
Program (independent
of
having been made by running
the
Program). Whether
that
is
true depends
on
what
the Program
does.
1.
You
may copy and
distribute
verbatim copies
of
the
Program's
source code
as
you receive it, in any medium, provided
that
you
conspicuously and appropriately publish on each copy an appro-
priate
copyright
notice and disclaimer
of
warranty; keep intact
all
the
notices that refer
to
this License and
to
the absence
of
any
warranty; and give any other recipients
of
the
Program a copy
of
this license along
with
the Program.
You
may charge a fee for
the
physical act
of
transferring a copy,
and you may at
your
option
offer
warranty
protection
in ex-
change for a
fee
.
2.
You
may modify your copy or copies
of
the
Program
or
any por-
tion
of
it. thus forming a
work
based
on
the
Program, and copy
and distribute such modifications or
work
under
the
terms
of
Sec-
tion 1above, provided
that
you also meetall
of
these conditions:
a)
You
must
cause
the
modified
files
to
carry
prominent
no-
tices 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 partthereof,
to
be licensed
as
a whole at no charge
to
all
third parties underthe terms
of
this License.
c)
If
the
modified
program
normally
reads commands
inter-
actively 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 underthese conditions, and telling
the
user
how
to
view acopy
of
this License. (Exception:
if
the Program itself
is
interactive
but
does
not
normally
print
such an announce-
ment,
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 distributethem
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 permis-
sions 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
awork based on
the
Program)
on a volume
of
a storage or distribution medium does
not
bring
the otherwork under
the
scope
of
this License.
3.
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 1and 2 above provided
that
you also
do
one
of
thefollowing:
a)
Accompany
it
with
the
complete
corresponding
ma-
chine-readable source code, which must be distributed under
theterms
of
Sections 1and 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
amediumcustomarily used for software interchange; or,
c) Accompany it with the information you received as to the of-
fer
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 awork 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. Howev-
er, as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or
binaryform) with the major components (compiler, kernel, and so
on) of the operating system on which the executable runs, unless
thatcomponent itselfaccompanies 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 objectcode.
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 Li-
cense. 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 infull 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 grant-
ed 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 Li-
cense, they do not excuse you from theconditions of this License.
If you cannot distribute so as to satisfy simultaneously your ob-
ligations 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 applyand the section as awhole is intended to apply
in othercircumstances.
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 im-
plemented 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 be-
lieved to bea 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 Li-
cense incorporates
the limitation as if written in the body of this
License.
9. The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time. Such
new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each
version is given a distinguishing version number. If the
Program specifies a version number of this License which applies
to it and "any later version", you have the option of following the
terms and conditions either of that version or of any later version
published by
the Free Software Foundation. If the Program does
not specify a version number of this License, you may choose any
version ever published by the Free Software Foundation.
10.
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted
by the Free Software Foundation, write to the Free Software
Foundation; we sometimes makeexceptions for this. Our decision
will be
guided by the two goals of preserving the free status of all
derivatives
of our free software and of promoting the sharing and
reuse of softwaregenerally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED
BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRIT-
ING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE
THE PROGRAM "AS IS" WITHOUTWARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED
TO
IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, IN-
CLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUEN-
TIAL DAMAGES ARISING OUT
OF THE USE OR INABILITY TO USE
THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED
BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO
OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply TheseTerms to Your New Programs

If
you develop a new program, and you want
it
to
be
of
the greatest
possible use
to
the
public,
the
best way
to
achieve this
is
to
make
it
free software which everyone can redistribute and change under

To
do
so
, attach
the
following notices
to
the
program.
It
is
safest
to
attach them
to
the
start
of
each source file
to
mosteffectively convey
the
exclusion
of
warranty;
and
each
file
should have
at
least
the
"copyright"line and a pointer
to
where thefull notice
is
found.

Version 2.1, February 1999

Everyone is permitted to copy and distribute verbatim copies of this
license document,
but changing it is not allowed.
[This is
the first released version of the Lesser GPL. It also counts as
the successor of the GNU Library Public License, version 2, hence the
version number
2.1.]
Preamble
The licenses for
most software are designed to take away your free-
dom to share and change it. By contrast, the GNU General Public Li-
censes are intended to guarantee your freedom to share and change
free software--to make sure the software
is free for all its users.
This license, the Lesser General Public License, applies
to some spe-
cially designated software packages--typically libraries--of
the Free
Software Foundation and other authors who decide to use it.You can
use it too, but we suggest you first think carefully about whether this
license
or the ordinary General Public License is the better strategy to
use in any particular case, based onthe explanations below.
When we speak
of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure
that you have the freedom to distribute copies of free software (and
charge for this service
if you wish); that you receive source code or
can get it if you want it; that you can change the software and use
pieces of it in new free programs; and that you are informed that you
can
do these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library or if you modify it.
For example,
if you distribute copies of the library, whether gratis or
for a fee, you must give the recipients all the rights that we gave you.
You mustmake sure that they, too, receive or can get the source code.
If you linkothercode with the library, you must provide complete ob-
ject files to the recipients, so that theycan relinkthem with the library
after making changes
to the library and recompiling it. And you must
show
them these terms so they knowtheir rights.
We protect your rights with a two-step method: (1) we copyright the
library, and
(2) we offeryou this license, which gives you legal permis-
sion
to copy, distributeand/ormodifythe library.
To protect each distributor, we want to make it very clear that there
is no warranty for the free library. Also, if the library is modified by
someone else and passed on, the recipients should
know that what
they have
is not the original version, so that the original author's rep-
utation will
not be affected by problems that might be introduced by
others.
Finally, software patents pose a constant threat
to the existence of
any free program. We wish to make sure that a company cannot ef-
fectively restrict the
users of afree program by obtaining a restrictive
license
from a patent holder. Therefore, we insist that any patent
license obtained for a version of the library must be consistent with
the full freedom of use specified in this license.
Most
GNU software, including some libraries, is covered by the ordi-
nary
GNU General Public License.This license, the GNU Lesser General
Public License, applies
to certain designated libraries, and is quite
differentfrom the ordinary General Public License. We use this license
for certain libraries in order
to permit linking those libraries into non-
free programs.
When a program
is linked with a library, whether statically or using a

shared library, the combination
of
the
two
is
legally speaking a com-
bined work, a derivative
of
the original library.
The
ordinary General
Public License therefore permits such linking only
if
the entire com-
bination fits its criteria
of
freedom. The
Lesser
General Public License
permits more lax criteria for linking
other
code with the library.
We
call this license the"Lesser" General Public License because
it
does
Less
to
protect the user's freedom than the ordinary General Public
License. It also provides
other
free software developers
Less
of
an
advantage over competing non-free programs.
These
disadvantages
are the reason we use
the
ordinary General Public License for many
libraries. However, the
Lesser
license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need
to
en-
courage thewidest possible
use
of
a certain library,
so
that
it
becomes
a
de-facto
standard.
To
achieve this, non-free programs
must
be
allowed
to
use
the library. A more frequent
case
is
that
a free library
does the same
job
as
widely used non-free libraries. In this
case,
there
is
little
to
gain by limiting
the
free library
to
free software only,
so
we
use
the
Lesser
General Public License.
In other
cases,
permission
to
use a particular library in non-free pro-
grams enables agreater number
of
people
to
use
a large body
of
free
software. For example, permission
to
use the
GNU
C Library in non-
free programs enables many more people
to
use
the whole
GNU
op
-
erating system,
as
well
as
its variant,
the
GNU/Linux operating system.
Although the
Lesser
General Public License
is
Less
protective
of
the
users
'freedom, it does ensure that
the
user
of
a program
that
is linked
with
the
Library
has
the freedom and
the
wherewithal
to
run
that
program using a modified version
of
the Library.
The precise terms and conditions for copying, distribution and mod-
ification follow.
Pay
close attention
to
the difference between a"work
based on the library"and a
"work
that
uses
the library".The former
contains code derived from
the
library, whereas
the
latter
must be
combined
with
the library in order
to
run.

AND
CONDITIONS
FOR
COPYING, DISTRIBUTION
AND
MOD-
IFICATION
0. This License Agreement applies
to
any software library or
other
program which contains a notice placed by the copyright holder
or
other
authorized
party
saying
it
may be
distributed
under
the
terms
of
this Lesser General Public License (also called "this
License").
Each
licensee
is
addressed
as
"you':
A
"library
" means a
collection
of
software
functions
and/or
data prepared
so
as
to
be conveniently linked
with
application
programs (which use some
of
those functions and data)
to
form
executables.
The "Library': below, refers
to
any such software library
or
work
which has been
distributed
under these terms. A
"work
based
on the Library" means either the Library
or
any derivative work
under copyright law:
that
is
to
say
, a work containing the Library
or
a
portion
of
it, either verbatim
or
with
modifications
and/or
translated straightforwardly
into
another language. (Hereinafter,
translation
is
included
without
limitation in the term "modifica-
tion':)
"Source code" for a work means the preferred form
of
the work
for making modifications
to
it. For a library, complete source code
means all the source code forall modules
it
contains, plus any
as-
sociated interface definition files, plus the scripts used
to
control
compilation and installation
of
the library.
Activities
other
than copying, distribution and modification are
not
covered by this License; they
are
outside its scope.
The
act
of
running a program using the Library
is
not
restricted, and
output
from such a program
is
covered only
if
its contents constitute a
work based on the Library (independent
of
the
use
of
the Library

in atool for writing it). Whether that is true depends on what the
Librarydoes and what the program that
uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code
as you receive it, in any medium, provided
that you conspicuously and appropriately publish on each copy
an appropriate copyright notice and disclaimer of warranty; keep
intact all
the notices that refer to this License and to the absence
of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy,
and
you may at your option offer warranty protection in ex-
change for a
fee.
2. You may modifyyour copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications
or work under the terms of Section
1above, provided that you also meet all of these conditions:
a)
The modified workmust itselfbe a software library.
b) You must cause the files modified to carry prominent no-
tices stating that you changed the files and the date of any
change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table
of data to be supplied by an application program that
uses the facility, other than as an argument passed when the
facility is invoked, then you must make a good faith effort
to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs
whatever part
of its purpose remains meaningful.
(For example, a
function in a library to compute square roots
has a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any applica-
tion-supplied
function or table used by this function must be
optional:
if the application does not supply it, the square root
function must still compute square roots.)
These requirements apply
to the modified work as a whole. If
identifiablesections of thatwork are not derived from the Library,
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 awork based on the Library, 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 Library.
In addition, mere aggregation of another work not based on the
Library with the Library (or with a work based on the Library) on
a volume of a storage or distribution medium does not bring the
otherwork under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Pub-
lic License instead
of this License to a given copy of the Library.
To do this, you mustalter all the notices that refer to this License,
so that they refer to the ordinary GNU General Public License, ver-
sion
2, instead of to this License.(lf a newer version than version
2 of the ordinary GNU General Public License has appeared, then
you can specify
that version instead if you wish.)Do not make any
otherchange in these notices.
Once this change
is made in agiven copy, it is irreversible for that
copy, so the ordinary GNU General Public License applies to all

subsequent copies and derivative works made from
that
copy.
This
option
is
useful when you wish
to
copy
part
of
the code
of
the Library intoa program that
is
not
a library.
4.
You
may copy and distribute
the
Library (or a
portion
or
deriv-
ative
of
it,
under
Section
2)
in
object
code
or
executable
form
under the terms
of
Sections 1 and 2 above provided
that
you ac-
company
it
with the complete corresponding machine-readable
source code, which must be distributed under the terms
of
Sec-
tions 1 and 2 above on a medium customarily used for software
interchange.
If
distribution
of
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 satisfies
the
requirement
to
distribute the source code, even
though
third parties are
not
compelled
to
copy the source along
with
theobjectcode.
5.
A program
that
contains
no
derivative
of
any
portion
of
the Li-
brary,
but
is
designed
to
work
with
the Library by being compiled
or
linked
with
it, is called a
"work
that
uses
the
Library". Such
a work, in isolation,
is
not
a derivative
work
of
the
Library, and
therefore falls outside the scope
of
this License.
However, linking a "work
that
uses
the
Library"
with
the
Library
creates
an
executable
that
is
a derivative
of
the Library (because
it
contains portions
of
the Library), rather than a"work
that
uses
the library".
The
executable
is
therefore covered by this License.
Section 6 states terms fordistribution
of
such executables.
When a"work
that
uses
the Library"
uses
material from a header
file
that
is
part
of
the
Library,
the
object code
for
the
work may
be a derivative work
of
the Library even though the source code
is
not. Whether this
is
true
is
especially significant
if
the
work
can
be linked
without
the Library,
or
if
the work
is
itselfa library.The
threshold forthis
to
be true
is
not
precisely defined by law.
If
such
an
object file
uses
only
numerical parameters, data struc-
ture
layouts and accessors, and small macros and small
inline
functions (ten lines
or
less
in length), then the use
of
the object
file
is
unrestricted, regardless
of
whether
it
is
legally a derivative
work. (Executables containing this object code plus portions
of
the Library will still fall underSection
6.)
Otherwise,
if
the work
is
a derivative
of
the Library, you may dis-
tribute
the object code for
the
work
under
the
terms
of
Section
6. Any executables containing
that
workalso fall under Section
6,
whether
or
not
theyare linked directly
with
the Library itself.
6.
As
an exception
to
the
Sections above, you may also combine
or
link a"work
that
uses
the Library"
with
the Library
to
produce
a
work
containing
portions
of
the
Library, and
distribute
that
work under terms
of
your choice, provided
that
the
terms permit
modification
of
the work for the customer's own use and reverse
engineering fordebugging such modifications.
You
must
give
prominent
notice
with
each
copy
of
the
work
that the Library
is
used in
it
and
that
the Library and its use are
covered by this License.
You
must supply a copy
of
this License.
If
the work
during
execution displays copyright notices, you must
include the copyright notice for the Library among them,
as
well
as
a reference directing the user
to
the copy
of
this License. Also,
you must
do
one
of
these things:
a)
Accompany
the
work
with
the
complete
corresponding
machine-readable source
code
for
the
Library
including
whatever changes were used
in
the
work
(which
must
be
distributed under Sections 1 and 2 above); and,
if
the work
is
an executable linked
with
the
Library,
with
the
comp
lete
machine-readable"work
that
uses
the Library':
as
objectcode
and/or source code,
so
that
the user can
modify
the Library
and then relink
to
produce a modified executable containing
the
modified
Library. (It
is
understood
that
the
user
who
changes the contents
of
definitionsfiles in the Library will
not
