VERSION 1.0.3: public preview release

After many months of intense development, ZeroTier is proud to release version
1.0.3 of ZeroTier One.

This version focuses on under-the-hood and network level improvements to
prepare the way for more user-facing improvements in the months to come, as
well as new products built around the ZeroTier core.

1.0.3 contains a large number of changes, so we're not going to push it out
via our auto-update mechanism yet. We're going to update the download links
on the web site and let users try it out for a while first. If problems are
found, we'll do a 1.0.4 before we push it out to existing installations.

--
Important note for Linux users: we've decided to stop pushing auto-updates for
Linux, and this version's official Linux binaries are built without update
checking enabled. Linux is used mostly on servers, and based on user feedback
we've found that most users don't like anything auto-updating outside of the
normal package management channels. Instead, we'll be working over the next
few months to get ZeroTier One included in a number of upstream Linux
distributions. That way you'll be able to 'apt-get' or 'yum' install it and
stay up to date that way. Auto-updates will remain for Macintosh and Windows
users until/unless we can move to 'app store' deployment on those platforms.
--

Now for the change list. It's a big one!

NEW FEATURES and IMPROVEMENTS

 * Client support is in place for preferred relays on a per-network basis.
   This allows you to define statically assigned nodes that act as relays for
   indirect communication and connection setup for communication between peers
   on a given virtual network. If defined, they'll be used in preference to
   supernodes for this purpose. If they're offline, ZeroTier will fall back to
   global supernodes. This will require support on the web control panel for
   most users to use.

 * This version sends NAT "keepalive" packets every 20 seconds, which is
   similar to the behavior of most SIP phones. This should improve reliability
   behind NATs with short timeouts and certain cheap consumer NAT devices.

 * Improvements have been made to NAT traversal to traverse more symmetric
   NAT configurations, and to rate limit traversal attempts to avoid looking
   like a port scan.

 * New direct paths are now confirmed prior to use. This should improve
   reliability in cases where a NAT traversal attempt "half succeeds" by
   preventing the use of direct links that aren't actually usable.

 * A new geo-located TCP tunneling fallback implementation should improve
   performance for heavily firewalled users who can't use UDP.

 * ZeroTier now uses remotely reported accounts of your external IP address
   to detect changes in your network connectivity instead of relying on
   "fingerprinting" of the OS-level local network environment. This should
   improve reliability in cases where external routers have dynamic IPs or
   when changing between networks with different external IPs but similar
   internal addressing schemes. This should also improve reliability for
   use within virtual machines, since the external link address might change
   but the VM's link addresses will not.

 * We've eliminated the old Unix domain socket (or named pipe on Windows)
   control bus in favor of a local HTTP JSON API. It runs on 127.0.0.1
   port 9993 and can be accessed via standard HTTP. This improves
   interoperability with scripts and other tools and allows us to use
   HTML5 for the desktop UI component. See README.md in the service/
   subfolder of the source tree for JSON API documentation.

 * The old Qt GUI has been dropped in favor of a React-based HTML5 UI. The
   code for this is found in ui/, and if ui/ is present in the ZeroTier
   home folder the JSON API HTTP server will serve it on 127.0.0.1/9993.
   The Windows and Mac UIs are now web control wrappers which access this
   UI locally and automate the process of token lookup and login.

PACKAGING / INSTALLATION IMPROVEMENTS

 * The Macintosh version is now packaged as a .pkg file instead of the old
   .app that would download its components and bootstrap itself. Several
   Mac users had problems with this, so we made it a package instead.

 * The Windows installer now includes a cleaner driver installation module
   that installs the driver as part of the main MSI file instead of spawning
   a subprocess.

BUG FIXES

 * Windows now comes with an updated NDIS6 Ethernet tap device driver.
   If you still have the old NDIS5 driver installed you'll keep using it,
   so if you want to switch to the NDIS6 driver uninstall your old version
   and do a fresh install of the new one. NDIS5 is deprecated, so we are
   hoping an NDIS6 driver will fix a number of difficult to reproduce
   issues that some Windows users have reported. It will also likely
   improve performance.

 * Fixed a "pseudo" memory leak related to the old auto-update code. The
   amount of "committed" (but not used) memory would increase over time.
   Since this was not actual used memory it didn't cause real problems,
   but the issue is gone now.

 * A very rare threading deadlock was fixed.

 * Fix for Linux installer that would falsely recognize systemd on some
   Ubuntu systems.

DEEP UNDER THE HOOD

 * This version has been heavily refactored at the source code level! The
   node/ subfolder now contains the core ZeroTier network virtualization
   engine without any OS-specific or transport-specific code. This is in
   preparation for future plans around embedded devices, etc. There is now
   a public C-level API in include/ZeroTierOne.h that defines an interface
   to the node core.

 * A new network controller implementation is in 1.0.3 based on SQLite and
   the local JSON API control bus. IT HAS NOT BEEN HEAVILY TESTED YET, so we
   do not recommend using it in production until the next version. You are
   welcome to experiment with it.

-ZeroTier One - Network Virtualization Everywhere
+ZeroTier One
 ======
 
-ZeroTier One is an ethernet virtualization engine. It creates virtual switched LANs of almost unlimited size that span physical network boundaries. To the operating system these behave just like ordinary Ethernet ports. Everything just works, even as your computer moves around or your physical Internet link changes.
+ZeroTier is a software defined networking layer for Earth.
 
-It's intended to replace conventional hub-and-spoke VPNs, provide provider-neutral secure private backplane networks to multi-data-center and hybrid cloud deployments, allow remote access to embedded devices, and much more.
+It can be used for on-premise network virtualization, as a peer to peer VPN for mobile teams, for hybrid or multi-data-center cloud deployments, or just about anywhere else secure software defined virtual networking is useful.
 
-ZeroTier uses a peer to peer network with managed anchor points ("supernodes"). These are operated by ZeroTier Networks, and are free to use. They provides instant "zero configuration" startup, NAT traversal assistance, relaying in cases where NAT traversal doesn't work, and a trusted root authority for looking up peer public keys (identities). The supernodes run the same open-source software as regular nodes, are geographically distributed across three continents, and have remained stable for over a year. [This blog post](http://adamierymenko.com/decentralization-i-want-to-believe/) discusses the design rationale in some detail. *(TL;DR: this design represents a compromise between speed and ease of use and decentralization.)*
+ZeroTier One is our OS-level client service. It allows Mac, Linux, Windows, FreeBSD, and soon other types of clients to join ZeroTier virtual networks like conventional VPNs or VLANs. It can run on native systems, VMs, or containers (Docker, OpenVZ, etc.).
 
-ZeroTier One encrypts all traffic end-to-end with keys that only you control. Even when traffic is traversing our network we cannot decrypt it. It's not, however, a "strong privacy" tool since it would still be possible for us (or your ISP or anyone else in between) to observe "meta-data" about your traffic. If you need *that* level of anonymity, we recommend [Tor](https://www.torproject.org) or something similar. Onion routing is the only technology we're aware of that is capable of delivering that level of end-to-end privacy protection.
+Visit [ZeroTier's site](https://www.zerotier.com/) for more information. You can also download professionally packaged binary installers/packages for a variety of supported OSes there if you don't want to build ZeroTier One from source.
 
-At the moment the ZeroTier wire protocol is only documented in the source (start with the comments in Packet.hpp), but more formal documentation is planned for the near future. Encapsulation overhead is comparable to IPSec or OpenVPN.
+### Building from Source
 
-[Visit ZeroTier Networks on the web](https://www.zerotier.com/) for more information. Follow the [ZeroTier blog](https://www.zerotier.com/blog/), [Twitter feed](https://twitter.com/ZeroTier) and the main [GitHub project](https://github.com/zerotier/ZeroTierOne) to stay up to date. See the GitHub-hosted wiki (sidebar) for more technical info and help for various platforms. There's also a [support portal](https://www.zerotier.com/support/) for more general information.
+For Mac, Linux, and BSD, just type "make" (or "gmake" on BSD). You won't need much installed; here are the requirements for various platforms:
 
-### Getting Started
+ * Mac: Xcode command line tools, and [Packages](http://s.sudre.free.fr/Software/Packages/about.html) if you want to build an OSX .pkg installer ("make mac-dist-pkg"). It should build on OSX 10.7 or newer.
+ * Linux: gcc/g++ or clang/clang++ (Makefile will use clang by default if available.)
+ * FreeBSD (and other BSD): C++ compiler (G++ usually) and GNU make (gmake).
 
-Auto-updating binary packages that install easily [can be found here](https://www.zerotier.com/download.html) for officially supported platforms. Packages for popular Linux distributions that neatly wrap the Linux installer/uninstaller are coming soon.
+Each supported platform has its own *make-XXX.mk* file that contains the actual make rules for the platform. The right .mk file is included by the main Makefile based on the GNU make *OSTYPE* variable. Take a look at the .mk file for your platform for other targets, debug build rules, etc.
 
-If you want to build from source, clone this repository and see BUILDING.txt and RUNNING.txt. If you build manually you'll have to update manually, and we recommend doing so often as development is progressing very rapidly. (Protocol is pretty stable but you might miss out on new features or experience performance degradation if you're too far behind.)
+Windows, of course, is special. We build for Windows with Microsoft Visual Studio 2012 on Windows 7. A solution file is located in the *windows* subfolder. Newer versions of Visual Studio (and Windows) may work but haven't been tested. Older versions almost certainly will not, since they lack things like *stdint.h* and certain STL features. MinGW or other ports of gcc/clang to Windows should also work but haven't been tested. Build steps for Windows are a bit more complicated. For the moment you are on your own there.
 
-Once you are up and running, you have several options.
+Mobile versions are in progress. They don't work yet, and in any case only the glue code will be included in this repository. The full mobile apps are in private repositories on our own git server.
 
-ZeroTier provides ZeroTier One for free, but to help finance development and operations we have a [user-friendly freemium control panel on the web](https://www.zerotier.com/admin.html). This control panel lets you quickly and easily create your own networks, and the operation of their controller node(s) is left to us. Public networks created on our site are free, and private networks are free for up to ten devices. After that there is a monthly charge.
+### Supported Platforms
 
-You *only* need an account on our site if you want to use the control panel found there. Joining networks requires no account. To get authorized on a private network, just send your device's 10-digit ID to the network's administrator and they can add you.
+CPU architecture shouldn't matter unless it's smaller than 32-bit or something really bizarre like a "middle-endian" processor. We have reports of ZeroTier One running on arm32, arm64, and MIPS. It builds and runs out of the box on Raspberry Pi, BeagleBone, BananaPi, and other ARM-based developer/hobbyist boards.
 
-Public networks, as the name implies, can be joined without getting authorization from anyone. All you need is their 16-digit network ID. A public network called [Earth](https://www.zerotier.com/earth.html) (8056c2e21c000001) exists for everyone, but be sure your device is adequately secured and up to date before joining.
+ZeroTier is written in C and C++ (C++03 / ISO/IEC 14882:2003) and uses data structures and algorithms from the C++03 STL. We do not use any C++11 features (yet), since we want to support a few old and embedded platforms that don't have C++11 compilers. You *will* require a compiler and headers new enough to support 64-bit integers (long long) and the *stdint.h* header. The latter could also be faked by adding defines for things like *uint32\_t*, *int64\_t*, etc.
 
-Alternatively, you can run your own network configuration controller. This lets you run any network for free. To do this, start with the netconf-service/ subfolder of this project. You'll need to do a bit of system administration work and manually populate a Redis database, but it's not terribly hard if you're into that kind of thing.
+Typing "make selftest" will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures.
 
-More products and services will be forthcoming.
+### Running
 
-### Basic Troubleshooting
+Running *zerotier-one* with -h will show help.
 
-For about 95% of users, it just works.
+On Linux and BSD you can start the service with:
 
-If you are running a local system firewall, we recommend adding a rule permitting UDP port 9993 inbound and outbound. The binary Windows installer takes care of this for Windows' built-in firewall, but other platforms and third party firewall software may need this for optimal performance.
+    sudo ./zerotier-one -d
+
+A home folder for your system will automatically be created.
+
+The service is controlled via the JSON API, which by default is available at 127.0.0.1 port 9993. We include a *zerotier-cli* command line utility to make API calls for standard things like joining and leaving networks. The *authtoken.secret* file in the home folder contains the secret token for accessing this API. See README.md in [service/](service/) for API documentation.
+
+Here's where home folders live (by default) on each OS:
+
+ * Linux: /var/lib/zerotier-one
+ * BSD: /var/db/zerotier-one
+ * Mac: /Library/Application Support/ZeroTier/One
+ * Windows: \\ProgramData\\ZeroTier\\One (That's for Windows 7. The base 'shared app data' folder might be different on different Windows versions.)
+
+Running ZeroTier One on a Mac is the same, but OSX requires a kernel extension. We ship a signed binary build of the ZeroTier tap device driver, which can be installed on Mac with:
+
+    sudo make install-mac-tap
+
+This will create the home folder for Mac, place *tap.kext* there, and set its modes correctly to enable ZeroTier One to manage it with *kextload* and *kextunload*.
+
+We recommend using our binary packages on Windows, since there are several prerequisites such as a tap driver that must be installed on the system *and* in the home folder.
+
+### Joining A Network
+
+ZeroTier virtual networks are identified by 16-digit hexadecimal network IDs, while devices are identified by 10-digit addresses. To get your address run:
+
+    sudo zerotier-cli status
+
+(Use ./zerotier-cli if you're running it right from your build folder.)
+
+You should see something like:
+
+    200 info ########## ONLINE #.#.#
+
+That 10-digit hex code is you. It's derived via a one-way proof of work function from your cryptographic public key. Your public key can be found in *identity.public* in ZeroTier's home folder, while *identity.secret* contains your full identity including the secret portion of the key pair.
+
+(The identity files define your device's *identity*. Moving them to another system will move that identity. Be careful when cloning virtual machines that have identities stored on them. If two devices have the same identity, they'll "fight" over it and you won't know which device will receive network packets.)
+
+If you want to do a quick test, you can join [Earth](https://www.zerotier.com/earth.html). It's a global public network that anyone can join. Type:
+
+    sudo zerotier-cli join 8056c2e21c000001
+
+Then:
+
+    sudo zerotier-cli listnetworks
+
+At first it'll be in *REQUESTING\_CONFIGURATION* state. In a few seconds to a minute you should see something like:
+
+    200 listnetworks 8056c2e21c000001 earth.zerotier.net ##:##:##:##:##:## OK PUBLIC zt0 ##.##.##.##/##
+
+Earth will assign you an IP address in the "unofficially available" globally unrouted 28.0.0.0/7 IP block so as to avoid conflicts with local networks. (Your networks can use any IP scheme, or can even leave IP addresses unmanaged.) Once you get an IP, you should be able to ping something:
+
+    ping earth.zerotier.net
+
+Go to [http://earth.zerotier.net/](http://earth.zerotier.net/) to see a short little welcome page that will tell you your IP and Ethernet MAC address.
+
+Earth is a public place. If you don't want to stick around run:
+
+    sudo zerotier-cli leave 8056c2e21c000001
+
+The network (and associated interface) should be gone.
+
+Networks are created and administrated by network controllers. Most users will want to use our hosted controllers. Visit [our web site](https://www.zerotier.com/) for more information. Later in this README there are brief instructions about building ZeroTier One with network controller support for those who want to try running their own.
+
+Macintosh and Windows installers also install a GUI application.
+
+### Installing
+
+We don't have a "make install" rule quite yet. On Linux you can type:
+
+    make installer
+
+This will build a binary that, when run, will install ZeroTier One on most current Linux distributions. We also have RPM and DEB build files in *ext/installfiles/linux* that wrap this installer in packages for RedHat/CentOS and Debian/Ubuntu derived distributions. If *rpmbuild* is present on the system, the RPM will be built. If *dpkg-deb* is present, the DEB package will be built.
+
+On Mac the best way is to install [Packages](http://s.sudre.free.fr/Software/Packages/about.html) and use:
+
+    make mac-dist-pkg
+
+This builds a .pkg file that can be installed.
+
+BSD has no installer yet. We're working on it.
+
+Linux/BSD and Mac installations have an *uninstall.sh* file in their ZeroTier home folder that cleanly removes ZeroTier One from the system. Run this with:
+
+    sudo /path/to/ZeroTier/home/folder/uninstall.sh
+
+Windows installers are insane. We build our .MSI installers with [Advanced Installer Enterprise](http://www.advancedinstaller.com). The Advanced Installer project file is in *ext/installfiles/windows*. To avoid lasting psychological trauma we recommend leaving Windows installers alone and using the pre-built Windows binaries on our web site.
+
+### Using ZeroTier One in Docker Containers
+
+To run the ZeroTier One service in a Docker container, run it with "--device=/dev/net/tun --cap-add=NET_ADMIN". This will allow ZeroTier One to open a "tap" virtual network port inside the container.
+
+Alternately, you can use Ethernet bridging to bridge the *docker0* device on your system to a ZeroTier virtual network. This allows you to run ZeroTier One on the host and bridge the entire Docker network backplane to a virtual network or other hosts.
+
+We're working on better "official" Docker support. In the meantime there is a [user-contributed project here](https://github.com/davide/docker-zerotier).
+
+### Building with Network Controller Support
+
+**Warning: as of beta version 1.0.3 the new network controller is not heavily tested. We recommend waiting for 1.0.4 to deploy this in production.**
+
+Network controllers are nodes responsible for issuing configurations and certificates to members of ZeroTier virtual networks. Most users won't need to run their own, so this code is by default not included in the ZeroTier One binary.
+
+You can build a network controller on Linux or Mac with:
+
+    make ZT_ENABLE_NETWORK_CONTROLLER=1
+
+This will build a version that contains the Sqlite-backed network controller and associated extensions to the JSON local service control API. You will need the development headers for sqlite3 installed. On Mac these ship as part of Xcode, while on Linux they'll be found in packages for the various distributions.
+
+See the JSON API documentation in [service/](service/) for more information about how to control controllers.
+
+### Troubleshooting
+
+For most users, it just works.
+
+If you are running a local system firewall, we recommend adding a rule permitting UDP port 9993 inbound and outbound. If you installed binaries for Windows this should be done automatically. Other platforms might require manual editing of local firewall rules depending on your configuration.
+
+The Mac firewall can be founder under "Security" in System Preferences. Linux has a variety of firewall configuration systems and tools. If you're using Ubuntu's *ufw*, you can do this:
+
+    sudo ufw allow 9993/udp
+
+On CentOS check */etc/sysconfig/iptables* for IPTables rules. For other distributions consult your distribution's documentation. You'll also have to check the UIs or documentation for commercial third party firewall applications like Little Snitch (Mac), McAfee Firewall Enterprise (Windows), etc. if you are running any of those. Some corporate environments might have centrally managed firewall software, so you might also have to contact IT.
 
 ZeroTier One peers will automatically locate each other and communicate directly over a local wired LAN *if UDP port 9993 inbound is open*. If that port is filtered, they won't be able to see each others' LAN announcement packets. If you're experiencing poor performance between devices on the same physical network, check their firewall settings. Without LAN auto-location peers must attempt "loopback" NAT traversal, which sometimes fails and in any case requires that every packet traverse your external router twice.

 If you're interested, there's a [technical deep dive about NAT traversal on our blog](https://www.zerotier.com/blog/?p=226). A troubleshooting tool to help you diagnose NAT issues is planned for the future as are uPnP/IGD/NAT-PMP and IPv6 transport.

If this is truly the cause, perhaps ZeroTier failing to work on unpatched Windows systems is a feature not a bug.

-Running ZeroTier One
-======
-
-This guide is for those building and running from source. See BUILDING.md
-first.
-
-The wiki at GitHub contains several pages that are probably also of interest:
-  https://github.com/zerotier/ZeroTierOne/wiki
-
-### MacOS
-
-On Mac, the default ZeroTier home is:
-
-/Library/Application Support/ZeroTier/One
-
-ZeroTier ships with a kernel extension for its own tap device, which it
-stores in the above directory. To install this, type:
-
-sudo make install-mac-tap
-
-This will create the ZeroTier One home above if it does not exist and install
-the kext there. Note that the kext must be owned by root:wheel. The make
-rule for install-mac-tap takes care of that.
-
-Next, simply run the binary. It must be run as root to open the tap device.
-If run with no options, it will use the default home directory above.
-
-sudo ./zerotier-one &
-
-### LINUX
-
-On Linux, the default ZeroTier home is:
-
-/var/lib/zerotier-one
-
-Just type:
-
-sudo mkdir /var/lib/zerotier-one
-sudo ./zerotier-one &
-
-Your system must have the Linux tun/tap driver available (tun). All tested
-distributions so far ship with this driver as a module that will load
-automatically.
-
-UDP port 9993 must be open in your local firewall for this to work properly.
-How to do this varies by Linux distribution.
-
- - Opening port 9993 on Ubuntu
-
-Follow the Ubuntu documentation about UFW https://help.ubuntu.com/community/UFW
-
-Check if your UFW is active.
-
-sudo ufw status verbose
-
-If it is active, open UDP port 9993
-
-sudo ufw allow 9993/udp
-
-You should now be able to ping and browse earth.zerotier.net
-
-### FreeBSD
-
-FreeBSD is identical to Linux except that the default home is
-/var/db/zerotier-one instead of /var/lib.
-
-### WINDOWS
-
-Run zerotier-one.exe -h for help. There's a command to install the current
-binary as a service to run it that way, and another option to run it from
-the Windows console.
-
-### Once you're up and running...
-
-To use the command line interface, see this guide:
-  https://github.com/zerotier/ZeroTierOne/wiki/Command-Line-Interface
-
-If you want to test by joining the Earth network, try:
-  sudo ./zerotier-cli join 8056c2e21c000001
-
-An interface called 'zt####' should appear and should get an IP address in
-the 28.0.0.0/7 range (28.* or 29.*) within a few seconds or so. Then try
-pinging earth.zerotier.net or navigating to http://earth.zerotier.net/ in
-a web browser.

-Qt GUI
-======

-This is the Qt GUI distributed for Mac and Windows. It should build on Linux too if you've got Qt installed.

-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;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 them 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. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary.

-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The precise terms and conditions for copying, distribution and modification follow. &lt;/p&gt;

Definitions.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;“This License” refers to version 3 of the GNU General Public License. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A “covered work” means either the unmodified Program or a work based on the Program. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section1&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Source Code.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The Corresponding Source for a work in source code form is that same work. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section2&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;2&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Basic Permissions.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section3&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;3&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Protecting Users' Legal Rights From Anti-Circumvention Law.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section4&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;4&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Conveying Verbatim Copies.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section5&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;5&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Conveying Modified Source Versions.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: &lt;/p&gt;
-&lt;ul style=&quot;margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;&quot;&gt;&lt;li style=&quot; margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;a) The work must carry prominent notices stating that you modified it, and giving a relevant date. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. &lt;/li&gt;&lt;/ul&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section6&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;6&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Conveying Non-Source Forms.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: &lt;/p&gt;
-&lt;ul style=&quot;margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;&quot;&gt;&lt;li style=&quot; margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. &lt;/li&gt;&lt;/ul&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section7&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;7&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Additional Terms.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: &lt;/p&gt;
-&lt;ul style=&quot;margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;&quot;&gt;&lt;li style=&quot; margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;d) Limiting the use for publicity purposes of names of licensors or authors of the material; or &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or &lt;/li&gt;
-&lt;li style=&quot; margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. &lt;/li&gt;&lt;/ul&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section8&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;8&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Termination.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section9&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;9&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;. Acceptance Not Required for Having Copies.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section10&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;0. Automatic Licensing of Downstream Recipients.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section11&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1. Patents.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section12&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;2. No Surrender of Others' Freedom.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section13&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;3. Use with the GNU Affero General Public License.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section14&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;4. Revised Versions of this License.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The Free Software Foundation may publish revised and/or new versions of the GNU 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. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section15&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;5. Disclaimer of Warranty.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;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. &lt;/p&gt;
-&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;a name=&quot;section16&quot;&gt;&lt;/a&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;1&lt;/span&gt;&lt;span style=&quot; font-size:medium; font-weight:600;&quot;&gt;6. Limitation of Liability.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. &lt;/p&gt;

Interpretation of Sections 15 and 16.&lt;/span&gt; &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;END OF TERMS AND CONDITIONS &lt;/p&gt;

-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;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. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;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 state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found. &lt;/p&gt;
-&lt;p style=&quot; margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;span style=&quot; font-family:'Courier New,courier';&quot;&gt;    &amp;lt;one line to give the program's name and a brief idea of what it does.&amp;gt;&lt;/span&gt;&lt;/p&gt;
