includes several devices in one box. First, there's the Wireless Router, which
lets you connect Wireless-G or Wireless-B devices to the network.
There's also a built-in 4-port full-duplex 10/100 Switch to connect your
wired-Ethernet devices. Connect four PCs directly, or daisy-chain out to more
hubs and switches to create as big a network as you need. This router equip
with powerful firewall and DoS protection, which can give the user maximum
protection to prevent from damage by malicious internet user. The UPnP and
MSN messenger support can provide the environment for user to surfing
internet without any trouble.
This product operates in 2.4 GHz frequency bands, providing fast (up to 54
Mbps) and secure (support WPA, WPA2 and WEP) connections to 802.11 b/g
networks. GN-BR03GM overcomes environment multi-path effect by MIMO
feature to keep stable wireless performance.
** MIMO (multiple-in, multiple-out) takes advantage of multiplexing to increase wireless bandwidth and range.
MIMO algorithms send information out over two or more antennas and the information is received via multiple
antennas as well.

Chapter 2
Wireless Networking
A wireless local area network (or Wi-Fi for short) is exactly like a regular local
area network (LAN), except that each computer in the wireless network uses a
wireless device to connect to the network. Computers in a wireless network
share the same frequency channel and SSID, which is an identification name
shared by the wireless devices belonging to the same wireless network.
The Router transmits data to PCs equipped with wireless network adapters,
which can roam within a certain radial range of the Router. You can arrange the
Router and multiple access points to work in succession to extend the roaming
range, and you can set up your wireless network to communicate with your
Ethernet hardware as well. The big advantage of Wi-Fi is its simplicity. You can
connect computers anywhere in your home or office without the need for wires.
The computers connect to the network using radio signals, and computers can
be up to 100 feet or so apart.
Wireless Network Layout
The BR03GM AirCruiser MIMO Router has
been specifically designed for use with
both your 802.11b and 802.11g products,
and retains full backward compatibility.
After you have finished setting up your
GN-BR03GM AirCruiser MIMO Router,
your home network will be similar to the
diagram shown at the right.

MTU (Maximum Transmission Unit)
The largest packet unit is sent from your computer to the network. Any
message larger than MTU will be divided into smaller packets before being sent.
You should keep the default setting (1500). Setting MTU size is largely a
process of trial-and-error: If you suspect your MTU setting is causing a
connection problem, start with the maximum value of 1500, and then
reduce the size down to 1400 until the problem goes away.
NAT Setup
The Network Address Translation (NAT) is a standard that allows multiple
computers on a private network to share a single IP address.
Universal Plug and Play (UPnP) is a technology based on Internet standards
and technologies, such as TCP/IP, HTTP, and XML, that allows devices on a
network to automatically connect with other devices.
UPnP Delete Time
Select the duration that UPnP will be active. Since allowing this may present a
security risk, the default setting is 0.
If the WAN IP address and LAN IP address obtained from DHCP
server are from the same subnet, the LAN IP address will
automatically change to another subnet and reboot the router.

also working with devices from different vendors.
802.11g Only Mode
The mixture of both 11b and 11g traffic on your wireless network results in the
former reducing the performance of the latter. For this reason, the BR03GM
802.11g Only Mode allows you to restrict all traffic to 11g (54Mbps) traffic only.
Keep in mind, however that enabling this feature comes at the expense of
eliminating all 11b based traffic will be received or transmitted by the BR03GM.
Enable will restrict all traffic to 802.11g traffic, while disable will allow a mixture
of both 11b and 11g. The default setting is disable.
Channel
The channel may be manually changed (if there are other wireless networks

operating in your area) by selecting a channel from the drop-down list.
SSID
The SSID (Service Set Identifier) is the name of your wireless network. The
SSID is up to 32 ASCII characters in length and case sensitive (i.e. Letters in
upper case “A~Z” and lower case “a~z” are unique). The default SSID is
“GIGABYTE”. To change the SSID, type in the SSID you want to use in the
SSID field and click Submit. If you make a change to the SSID, any wireless
devices on your network must also be reconfigured to connect to the new
network name.
Rate
Select a wireless data transmission rate from the drop- down list. The default
setting auto/best automatically detects and sets the optimum transmission rate.
Hidden SSID
For security purposes, you may choose to hide your network’s SSID by
selecting enable from the drop-down list. This will prevent computers scanning
for the presence of wireless networks to detect your network name. The default
setting is disable.
Authentication Type
Select an authentication type from the drop-down list. The default setting is
Open System.
Open System: The sender and the receiver do NOT share a secret key. Each
party generates its own key-pair and asks the receiver to accept a randomly
generated key. Once accepted, this key will only be used for a short period of
time. Afterwards, a new key will be generated and agreed upon.
Shared Key: Authentication is based upon a secret key shared by both the
sender and the receiver. If Shared Key is selected, you cannot choose the
WEP disable option.
WPA Pre-shared key:, The WPA Pre-shared Key authentication standard uses
a password or “ key” between 8 and 32 characters. This encryption key is
changed after every dialog box using the Temporary Key Integrity Protocol
(TKIP), which allows users to change keys based on dialog box and
automatically synchronize keys between devices on the network. The TKIP
encryption algorithm is stricter than the one used by WEP but is based on the
same standard.
WPA: The 802.1x authentication protocol, allows users to authenticate wireless
network access through a RADIUS Server and is a required by WPA standard.
If no RADIUS Server exists in your network environment, you still can use WPA
through the use of WPA Pre-shared Key.
WEP Key
The GN-BR03GM supports two WEP standards: 64-bit and 128-bit. The 64-bits
26

encryption uses 40 bits as a secret key, (user-defined) and the remaining 24
bits are reserved. The 128-bits encryption uses 104 bits as a secret key,
(user-defined) and the remaining 24 bits are reserved.
WPA Re-key
Enabling the requirement for WPA rekeying of a Passphrase for increased
security. Default is disable.
WPA Re-key Timer
Specify time (in minutes) for expiration of the current WPA Key.
WPA PSK Passphrase
The Passphrase must be between 8 and 64 characters.
WPA PSK Re-key
A user without a RADIUS server, may specify generating a new WPA PSK key
more frequently than each time he connects to the network.

The WDS Tab
Figure 26: WDS Configuration
Wireless Distribution System (WDS) technology enables several access points
to increase the coverage of a wireless network. Although enterprises or home
users can reduce most wiring problems by using access points that support
WDS, they still need cables to connect external ISP.
To use WDS, please make sure:
ꢁ
ꢁ
All routers/AP’s participating in the WDS must use the same RF Channel
DHCP (if used) must only be enabled on the bridge Router and not on
the node AP’s.
Example: Suppose Router1 is connected to the DSL modem, and uses DHCP
to dish out IP’s to your WLAN. To use Router1 to bridge to a remote AP, key
in AP’s Wireless MAC Address in Router1’s WDS configuration list and select
“enable” then press Submit. In AP’s LAN settings, disable DHCP and assure
the AP uses the same RF Channel as the Router1. You should now be able
to connect to Router1 through AP.
Note that bridging between different vendors wireless gear is not
guaranteed. Your GN-BR03GM may only create a WDS environment with other
Gigabyte Routers or GIGABYTE Access Points.

Figure 29: DMZ Setup
With a firewall setup, it sometimes necessary to place some clients (e.g.
Internet games, video conferencing, or VPN connections) outside of the firewall
while leaving the others protected. You can do this using a Demilitarized Zone.
The DMZ feature allows you to specify the IP address of the computer that will
be placed outside the firewall of your network. Enter the IP Address of your
computer (e.g. 192.168.1.2) into the LAN IP Address field and click the Submit
button.
Note: DMZ servers pose a security risk. A computer
designated as the default DMZ server loses much of the
protection of the firewall, and is exposed to exploits from the
Internet. If compromised, the DMZ server can be used to
attack your network.

FAQ
This section provides solutions to common problems that may occur during
installation, configuration or use of the GN-BR03GM.
Q: What is the default IP address for the BR03GM?
A: 192.168.1.254
Q: I can’t remember the password or IP address of the router.
A: You can resolve this by pressing the “Init” button on the side of the router.
You can also reset the Router from the Web Utility <Initialization Page>.
The Router will reboot and all settings (including the default password) will
be restored to their default values.
Q: What is the default username and password for the BR03GM?
A: Username is “admin” and password is “admin”.
Q: Why do I have to setup ISP information into my Router?
A: ISPs require a special login protocol, in which you must enter a login
name and password in order to access the Internet. In order to share the
Internet connection among several computers, you must configure it with
the TCP/IP information that your one PC would normally use.
Q: Where in the network do I connect the router?
A: In a typical environment, the GN-BR03GM is installed directly onto the
ADSL/Cable Modem. Plug the RJ45 Ethernet cable of the ADSL or Cable
Modem into the WAN port of the Router.
Q: Why should I use the GN-BR03GM to work as a DHCP server?
A: Using the BR03GM Router as a DHCP server By default, the router will
function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all
computers connected to the router's LAN. The assigned default gateway
address is the LAN address of the router. IP addresses will be assigned to
the attached PCs from a pool of addresses specified in this menu. Each
pool address is tested before it is assigned to avoid duplicate addresses
on the LAN. DCHP helps prevent IP conflicts.
Q: What is the IEEE 802.11g standard?
A: The IEEE 802.11g standard specifies data rates of up to 54 Mbps in the
2.45-GHz band. It uses Orthogonal Frequency Division Multiplexing
(OFDM), which is provided by this standard and is compatible with
802.11b standard offering speeds of about 11 Mbps. This standard uses
Complementary Code Keying (CCK) modulation. Both 11g and 11b can
operate at a range of up to 300 feet.

Appendix E
Glossary
802.11e
An IEEE standard that adds Quality of Service (QoS) features and multimedia
support to the existing 802.11b, 802.11g, and 802.11a wireless networks.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that
converts existing twisted-pair telephone lines into access paths for high-speed
communication of various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it
needs to act as a MDI or MDIX port. The auto- MDI/MDIX capability eliminates
the need for crossover cables.
Auto-negotiate
To automatically determine the correct setting. The term is often used with
communications and networking
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for
automating the configuration of computers that use TCP/IP. DHCP can be used
to automatically assign IP addresses, to deliver TCP/IP stack configuration
parameters such as the subnet mask and default router, and to provide other
configuration information such as the addresses for printer, time and news
servers.
DMZ
In computer networks, a DMZ (demilitarized zone) is a computer host or small
network inserted as a "neutral zone" between a company's private network and
the outside public network. It prevents outside users from getting direct access
to a server that stores company data. Typically, the DMZ contains devices
accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP
(e-mail) servers and DNS servers.
DNS
The Domain Name System (DNS) is a distributed Internet directory service.
DNS is used mostly to translate between domain names and IP addresses, and
to control Internet email delivery. Most Internet services rely on DNS to work. If
DNS fails, web sites cannot be located and email delivery service will be
suspended.
Dynamic IP Address
An IP address is automatically assigned to a user’s AP in a TCP/IP network
typically by a DHCP server.

Firewall
A system designed to prevent unauthorized access to or from a private network.
Firewalls can be implemented in both hardware and software, or a combination
of both. Firewalls are frequently used to prevent unauthorized Internet users
from accessing private networks connected to the Internet, especially intranets.
All messages entering or leaving the intranet pass through the firewall, which
examines each message and blocks those that do not meet the specified
security criteria.
Gateway
A device, usually a Router, that connects hosts on a local network to other
networks.
IP Address
Every PC on the Internet has a unique identifying number, called an IP Address.
A typical IP address looks like this: 216.27.61.137
IPSec
IPSec stands for IP Security. It provides authentication and encryption over the
Internet. It functions at Layer 3 and thus secures everything on the network. It
has become a standard protocol used for virtual private networks (VPNs).
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access
Control) address is your computer's unique hardware number. Usually written
as: 01:23:45:67:89:ab
MTU
The size in bytes of the largest packet that can be sent or received.
NAT
A technique by which several hosts share a single IP address for accessing to
the Internet.
Ping (Packet Internet Groper)
A utility to determine whether a specific IP address is accessible. It works by
sending a packet to the specified address and waiting for a reply. PING is used
primarily to troubleshoot Internet connections.
SSID
SSID is the name representing the Router in WLAN.
PPPoE
Point-to-Point over Ethernet is a protocol for connecting remote hosts to the
Internet over an always-on connection by simulating a dial-up connection.
QoS
Quality of Service. Required to support wireless multimedia applications and
64

GN-BR03GM AirCruiser MIMO Router
advanced traffic management. QoS enables Wi-Fi access points to prioritize
traffic and optimize the way shared network resources are allocated among
different applications. Without QoS, all applications running on different devices
have equal opportunity to transmit data frames. That works well for data traffic
from applications such as web browsers, file transfers, or e-mail but it is
inadequate for multimedia applications. Voice over Internet Protocol (VoIP),
video streaming, and interactive gaming are highly sensitive to latency
increases and throughput reductions and require QoS. QoS extensions for
802.11 networks will be addressed in the upcoming IEEE 802.11e standard.
Router
A device that forwards data packets along networks. A router is connected to at
least two networks, commonly two LANs or WANs or a LAN and its ISP
network. Routers are located at gateways, the places where two or more
networks connect.
Subnet Mask
A mask used to determine which subnet an IP address belongs to. An IP
address has two components, the network address and the host address.
Subnetting enables the network administrator to further divide the host part of
the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of
communications protocols used to connect hosts on the Internet.
VPN
Virtual private networks are secured private network connections, built on top of
publicly accessible infrastructure, such as the Internet or the public telephone
network. VPNs typically employ some combination of encryption, digital
certificates, strong user authentication and access control to provide security to
the traffic they carry. They usually provide connectivity to many machines
behind a gateway or firewall.
WAN
Wide Area Network, a communication network that covers a relatively broad
geographic area, consisting of two or more LANs. Broadband communication
over the WAN is often through public networks such as the ADSL or Cable
systems, or through leased lines or satellites. To simplify it, please image
network as a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm, as described in the IEEE 802.11 standard.
WMM™
Wi-Fi Multimedia. A group of features for wireless networks that improve the
user experience for audio, video and voice applications. WMM is based on a
subset of the IEEE 802.11e WLAN QoS draft standard. WMM adds prioritized

GN-BR03GM AirCruiser MIMO Router
capabilities to Wi-Fi networks and optimizes their performance when multiple
concurring applications, each with different latency and throughput
requirements, compete for network resources. By using WMM, end-user
satisfaction is maintained in a wider variety of environments and traffic
conditions. WMM makes it possible for home network users and enterprise
network managers to decide which data streams are most important and assign
them a higher traffic priority.

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 Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by the GNU Library 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 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 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 modify it.
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 show them these terms so they know their rights.

GN-BR03GM AirCruiser MIMO Router
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. 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 that any problems introduced
by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software 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's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright
holder saying it may be distributed under the terms 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 derivative 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 "modification".) 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 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 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 exchange for a fee.
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.
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 1 and 2 above provided that you also do one of the
73
Download from Www.Somanuals.com. All Manuals Search And Download.
GN-BR03GM AirCruiser MIMO Router
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.
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
74

GN-BR03GM AirCruiser MIMO Router
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 make exceptions
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 software generally.
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 WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 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,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 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

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 the public, 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 an idea of what it does.

Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General
Public License. Of course, the commands you use may be called something other than `show w' and
`show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a
"copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'

This General Public License does not permit incorporating your program into proprietary programs. If
your program is a subroutine library, you may consider it more useful to permit linking proprietary
applications with the library. If this is what you want to do, use the GNU Lesser General Public License
instead of this License.
