+##0.8.2
+
++ Currency: Allow mixed letters and numbers in currencies
+
++ Deprecate account_tx map/reduce/filter
+
++ Fix: correct requestLedger arguments
+
++ Fix: missing subscription on error events for some server methods
+
++ Fix: orderbook reset on reconnect
+
++ Fix: ripple-lib crashing. Add potential missing error handlers
+
+
+##0.8.1
+
++ Wallet: Add Wallet class that generates wallets
+
++ Make npm test runnable in Windows.
+
++ Fix several stability issues, see merged PR's for details
+
++ Fix bug in Amount.to_human_full()
+
++ Fix undefined fee states when connecting to a rippled that is syncing
+
+
+##0.8.0
+
++ Orderbook: Added tracking of offer funds for determining when offers are not funded
+
++ Orderbook: Added tests
+
++ Orderbook: Update owner funds
+
++ Transactions: If transaction errs with `tefALREADY`, wait until all possible submissions err with the same before emitting `error`. Fixes a client "Transaction malformed" bug.
+
++ Transactions: Track submissions, don't bother submitting to unconnected servers
+
++ Request: `request.request()` now accepts an array of servers as first argument. Servers can be represented with URL, or the server object itself.
+
++ Request: `request.broadcast()` now returns the number of servers request was sent to
+
++ Server: Acquire host information from server without additional request
+
++ Amount: Add a constant for the maximum canonical value that can be expressed as a Ripple value
+
++ Amount: Make Constants static fields on the class, instead of a seperate export
+
+
+##0.7.39
+
++ Improvements to multi-server support. Fixed an issue where a server's score was not reset and connections would keep dropping after being connected for a significant amount of time.
+
++ Improvements in order book support. Added support for currency pairs with interest bearing currencies. You can request an order book with hex, ISO code or full name for the currency.
+
++ Fix value parsing for amount/currency order pairs, e.g. `Amount.from_human("XAU 12345.6789")`
+
++ Improved Amount parsing from human readable string given a hex currency, e.g. `Amount.from_human("10 015841551A748AD2C1F76FF6ECB0CCCD00000000")`
+
++ Improvements to username normalization in the vault client
+
++ Add 2-factor authentication support for vault client
+
++ Removed vestiges of Grunt, switched to Gulp
+
+
+##0.7.37
+
++ **Deprecations**
+
+    1. Removed humanistic amount detection in `transaction.payment`. Passing `1XRP` as the payment amount no longer works.
+    2. `remote.setServer` uses full server URL rather than hostname. Example: `remote.setServer('wss://s`.ripple.com:443')`
+    3. Removed constructors for deprecated transaction types from `transaction.js`.
+    4. Removed `invoiceID` option from `transaction.payment`. Instead, use the `transaction.invoiceID` method.
+    5. Removed `transaction.transactionManager` getter.
+
++ Improved multi-server support. Servers are now ranked dynamically, and transactions are broadcasted to all connected servers.
+
++ Automatically ping connected servers. Client configuration now should contain `ping: <seconds>` to specify the ping interval.
+
++ Added `transaction.lastLedger` to specify `LastLedgerSequence`. Setting it this way also ensures that the sequence is not bumped on subsequent requests.
+
++ Added optional `remote.accountTx` binary parsing.
+    ```js
+      {
+        binary: true,
+        parseBinary: false
+      }
+    ```
++ Added full currency name support, e.g. `Currency.from_json('XRP').to_human({full_name:'Ripples'})` will return `XRP - Ripples`
+
++ Improved interest bearing currency support, e.g. `Currency.from_human('USD - US Dollar (2.5%pa)')`
+
++ Improve test coverage
+
++ Added blob vault client.  The vault client facilitates interaction with ripple's namespace and blob vault or 3rd party blob vaults using ripple's blob vault software (https://github.com/ripple/ripple-blobvault). A list of the available functions can be found at [docs/VAULTCLIENT.md](docs/VAULTCLIENT.md)
+
+
+##0.7.35
+
++ `LastLedgerSequence` is set by default on outgoing transactions. This refers to the last valid ledger index (AKA sequence) for a transaction. By default, this index is set to the current index (at submission time) plus 8. In theory, this allows ripple-lib to deterministically fail a transaction whose submission request timed out, but whose associated server continues to emit ledger_closed events.
+
++ Transactions that err with `telINSUF_FEE_P` will be automatically resubmitted. This error indicates that the `Fee` supplied in the transaction submission request was inadquate. Ideally, the `Fee` is tracked by ripple-lib in real-time, and the resubmitted transaction will most likely succeed.
+
++ Added Transaction.iff(function(callback) { }). Callback expects first argument to be an Error or null, second argument is a boolean which indicates whether or not to proceed with the transaction submission. If an `iff` function is specified, it will be executed prior to every submission of the transaction (including resubmissions).
+
++ Transactions will now emit `presubmit` and `postsubmit` events. They will be emitted before and after a transaction is submitted, respectively.
+
++ Added Transaction.summary(). Returns a summary of a transaction in semi-human-readable form. JSON-stringifiable.
+
++ Remote.requestAccountTx() with `binary: true` will automatically parse transactions.
+
++ Added Remote.requestAccountTx filter, map, and reduce.
+
+```js
+  remote.requestAccountTx({
+    account: 'retc',
+    ledger_index_min: -1,
+    ledger_index_max: -1,
+    limit: 100,
+    binary: true,
+
+    filter: function(transaction) {
+      return transaction.tx.TransactionType === 'Payment';
+    },
+
+    map: function(transaction) {
+      return Number(transaction.tx.Amount);
+    },
+
+    reduce: function(a, b) {
+      return a + b;
+    },
+
+    pluck: 'transactions'
+  }, console.log)
+```
+
++ Added persistence hooks.
+
++ General performance improvements, especially for long-running processes.

+
+##Quickstart
+
+`Remote.js` ([remote.js](https://github.com/ripple/ripple-lib/blob/develop/src/js/ripple/remote.js)) is the point of entry for interacting with rippled
+
+```js
+/* Loading ripple-lib with Node.js */
+var Remote = require('ripple-lib').Remote;
+
+/* Loading ripple-lib in a webpage */
+// var Remote = ripple.Remote;
+
+var remote = new Remote({
+  // see the API Reference for available options
+  servers: [ 'wss://s1.ripple.com:443' ]
+});
+
+remote.connect(function() {
+  /* remote connected */
+  remote.request('server_info', function(err, info) {
+
+  });
+});
+```
+
+##Running tests
+
+1. Clone the repository
+
+2. `cd` into the repository and install dependencies with `npm install`
+
+3. `npm test` or `node_modules/.bin/mocha test/*-test.js`
+
+**Generating code coverage**
+
+ripple-lib uses `istanbul` to generate code coverage. To create a code coverage report, run `npm test --coverage`. The report will be created in `coverage/lcov-report/`.

+##Generating a new Ripple Wallet
+
+  ```js
+    var Wallet = require('ripple-lib').Wallet;
+
+    var wallet = Wallet.generate();
+    console.log(wallet);
+    // { address: 'rEf4sbVobiiDGExrNj2PkNHGMA8eS6jWh3',
+    //   secret: 'shFh4a38EZpEdZxrLifEnVPAoBRce' }
+  ```
+
+##Connecting to the Ripple network
+
+1. [Get ripple-lib](README.md#getting-ripple-lib)
+2. Load the ripple-lib module into a Node.js file or webpage:
+  ```js
+  /* Loading ripple-lib with Node.js */
+  var Remote = require('ripple-lib').Remote;
+
+  /* Loading ripple-lib in a webpage */
+  // var Remote = ripple.Remote;
+  ```
+3. Create a new `Remote` and connect to the network:
+  ```js
+  var remote = new Remote({options});
+
+  remote.connect(function() {
+    /* remote connected, use some remote functions here */
+  });
+  ```
+  __NOTE:__ See the API Reference for available [`Remote` options](REFERENCE.md#1-remote-options)
+
+4. You're connected! Read on to see what to do now.
+
+
+##Sending rippled API requests
+
+`Remote` contains functions for constructing a `Request` object. 
+
+A `Request` is an `EventEmitter` so you can listen for success or failure events -- or, instead, you can provide a callback.
+
+Here is an example, using [request_server_info](https://ripple.com/wiki/JSON_Messages#server_info).
+
++ Constructing a `Request` with event listeners
+```js
+var request = remote.request('server_info');
+
+request.on('success', function onSuccess(res) {
+  //handle success
+});
+
+request.on('error', function onError(err) {
+  //handle error
+});
+
+request.request();
+```
+
++ Using a callback:
+```js
+remote.request('server_info', function(err, res) {
+  if (err) {
+    //handle error
+  } else {
+    //handle success
+  }
+});
+```
+
+__NOTE:__ See the API Reference for available [`Remote` functions](REFERENCE.md#2-remote-functions)
+
+
+##Listening to the network
+
+See the [wiki](https://ripple.com/wiki/JSON_Messages#subscribe) for details on subscription requests.
+
+```js
+ /* Loading ripple-lib with Node.js */
+  var Remote = require('ripple-lib').Remote;
+
+  /* Loading ripple-lib in a webpage */
+  // var Remote = ripple.Remote;
+
+  var remote = new Remote({options});
+
+  remote.connect(function() {
+    var request = remote.request('subscribe');
+
+    request.addStream('ledger'); //remote will emit `ledger_closed`
+    request.addStream('transactions'); //remote will emit `transaction`
+
+    request.on('ledger_closed', function onLedgerClosed(ledgerData) {
+	//handle ledger
+    });
+
+    request.on('transaction', function onTransacstion(transaction) {
+	//handle transaction
+    });
+
+    request.request(function(err) {
+      	if (err) {
+        } else {
+        }
+    });
+  });
+```

+
+##Submitting a payment to the network
+
+Submitting a payment transaction to the Ripple network involves connecting to a `Remote`, creating a transaction, signing it with the user's secret, and submitting it to the `rippled` server. Note that the `Amount` module is used to convert human-readable amounts like '1XRP' or '10.50USD' to the type of Amount object used by the Ripple network.
+
+```js
+/* Loading ripple-lib Remote and Amount modules in Node.js */ 
+var Remote = require('ripple-lib').Remote;
+var Amount = require('ripple-lib').Amount;
+
+/* Loading ripple-lib Remote and Amount modules in a webpage */
+// var Remote = ripple.Remote;
+// var Amount = ripple.Amount;
+
+var MY_ADDRESS = 'rrrMyAddress';
+var MY_SECRET  = 'secret';
+var RECIPIENT  = 'rrrRecipient';
+var AMOUNT     = Amount.from_human('1XRP');
+
+var remote = new Remote({ /* Remote options */ });
+
+remote.connect(function() {
+  remote.setSecret(MY_ADDRESS, MY_SECRET);
+
+  var transaction = remote.createTransaction('Payment', {
+    account: MY_ADDRESS, 
+    destination: RECIPIENT, 
+    amount: AMOUNT
+  });
+
+  transaction.submit(function(err, res) {
+    /* handle submission errors / success */
+  });
+});
+```
+
+###A note on transaction fees
+
+A full description of network transaction fees can be found on the [Ripple Wiki](https://ripple.com/wiki/Transaction_Fee).
+
+In short, transaction fees are very small amounts (on the order of ~10) of [XRP drops](https://ripple.com/wiki/Ripple_credits#Notes_on_drops) spent and destroyed with every transaction. They are largely used to account for network load and prevent spam. With `ripple-lib`, transaction fees are calculated locally by default and the fee you are willing to pay is submitted along with your transaction.
+
+Since the fee required for a transaction may change between the time when the original fee was calculated and the time when the transaction is submitted, it is wise to use the [`fee_cushion`](REFERENCE.md#1-remote-options) to ensure that the transaction will go through. For example, suppose the original fee calculated for a transaction was 10 XRP drops but at the instant the transaction is submitted the server is experiencing a higher load and it has raised its minimum fee to 12 XRP drops. Without a `fee_cusion`, this transaction would not be processed by the server, but with a `fee_cusion` of, say, 1.5 it would be processed and you would just pay the 2 extra XRP drops.
+
+The [`max_fee`](REFERENCE.md#1-remote-options) option can be used to avoid submitting a transaction to a server that is charging unreasonably high fees.
+
+
+##4. Submitting a trade offer to the network
+
+Submitting a trade offer to the network is similar to submitting a payment transaction. Here is an example for a trade that expires in 24 hours where you are offering to sell 1 USD in exchange for 100 XRP:
+
+```js
+/* Loading ripple-lib Remote and Amount modules in Node.js */ 
+var Remote = require('ripple-lib').Remote;
+var Amount = require('ripple-lib').Amount;
+
+/* Loading ripple-lib Remote and Amount modules in a webpage */
+// var Remote = ripple.Remote;
+// var Amount = ripple.Amount;
+
+var MY_ADDRESS = 'rrrMyAddress';
+var MY_SECRET  = 'secret';
+var GATEWAY = 'rrrGateWay';
+
+var remote = new Remote({ /* Remote options */ });
+
+remote.connect(function() {
+  remote.setSecret(MY_ADDRESS, MY_SECRET);
+
+  var transaction = remote.createTransaction('OfferCreate', {
+    account: MY_ADDRESS,
+    taker_pays: '1',
+    taker_gets: '1/USD/' + GATEWAY
+  });
+
+  transaction.submit(function(err, res) {
+    /* handle submission errors / success */
+  });
+});
+```

+});
+```
+
+##Transaction events
+
+[Transaction](https://github.com/ripple/ripple-lib/blob/develop/src/js/ripple/transaction.js) objects are EventEmitters. They may emit the following events.
+
++ `final` Transaction has erred or succeeded. This event indicates that the transaction has finished processing.
++ `error` Transaction has erred. This event is a final state.
++ `success` Transaction succeeded. This event is a final state.
++ `presubmit` Immediately before transaction is submitted
++ `postsubmit` Immediately after transaction is submitted
++ `submitted` Transaction has been submitted to the network. The submission may result in a remote error or success.
++ `resubmitted` Transaction is beginning resubmission.
++ `proposed` Transaction has been submitted *successfully* to the network. The transaction at this point is awaiting validation in a ledger.
++ `timeout` Transaction submission timed out. The transaction will be resubmitted.
++ `fee_adjusted` Transaction fee has been adjusted during its pending state. The transaction fee will only be adjusted if the remote is configured for local fees, which it is by default.
++ `abort` Transaction has been aborted. Transactions are only aborted by manual calls to `#abort`.
++ `missing` Four ledgers have closed without detecting validated transaction
++ `lost` Eight ledgers have closed without detecting validated transaction. Consider the transaction lost and err/finalize.
+
+##Complete payment example
+
+```js
+remote.setSecret(MY_ADDRESS, MY_SECRET);
+
+var transaction = remote.createTransaction('Payment', {
+  account: MY_ADDRESS,
+  destination: DEST_ADDRESS,
+  amount: AMOUNT
+});
+
+transaction.on('resubmitted', function() {
+  // initial submission failed, resubmitting
+});
+
+transaction.submit(function(err, res) {
+ // submission has finalized with either an error or success.
+ // the transaction will not be retried after this point
+});

+ripple-vault-client
+===================
+
+A javascript / http client to interact with Ripple Vault servers.
+
+The purpose of this tool is to enable applications in any javascript
+environment to login with the ripple vault and access the decrypted
+data stored using credentials originally obtained at ripple.com
+     
+        
+## Vault Client Usage
+
+    vaultClient = new ripple.VaultClient(domain);
+    
+    vaultClient.getAuthInfo(username, callback);
+    
+    vaultClient.getRippleName(address, url, callback);
+
+    vaultClient.exists(username, callback);
+    
+        
+
+    vaultClient.login(username, password, callback);
+
+    vaultClient.relogin(id, cryptKey, callback);
+
+    vaultClient.unlock(username, password, encryptSecret, callback);
+
+    vaultClient.loginAndUnlock(username, password, callback);
+    
+    
+    
+    vaultClient.register(options, callback);
+    
+    vaultClient.deleteBlob(options, callback);
+    
+    vaultClient.recoverBlob(options, callback);
+        
+    vaultClient.rename(options, callback);
+    
+    vaultClient.changePassword(options, callback);
+     
+    vaultClient.verify(username, token, callback);
+    
+    vaultClient.resendEmail(options, callback);
+    
+    vaultClient.updateProfile(options, fn);
+    
+
+# Blob Methods
+    
+    blob.encrypt();
+    
+    blob.decrypt(encryptedBlob);
+    
+    blob.encryptSecret(encryptionKey);
+    
+    blob.decryptSecret(encryptionKey, secret);
+    
+    blob.set(pointer, value, callback);
+    
+    blob.unset(pointer, callback);
+    
+    blob.extend(pointer, value, callback);
+    
+    blob.unshift(pointer, value, callback);
+    
+    blob.filter(pointer, field, value, subcommands, callback);
+    
+    
+## Identity Vault
+
+  The identity vault stores identity information inside the encrypted 
+  blob vault.  The identity fields can be additionally encrypted with the 
+  unlock key, that encrypts the secret, for added security. Methods are 
+  accessed from the 'identity' property of the blob object.
+
+
+# Identity fields
+  + name
+  + entityType (individual, corporation, organization)
+  + email
+  + phone
+  + address
+    + contact
+    + line1
+    + line2
+    + city
+    + postalCode
+    + region - state/province/region
+    + country
+  + nationalID
+    + number
+    + type (ssn, taxID, passport, driversLicense, other)
+    + country - issuing country
+  + birthday
+  + birthplace
+  
+  
+# Identity Methods
+
+    blob.identity.set(pointer, key, value, callback);
+    
+    blob.identity.unset(pointer, key, callback);
+    
+    blob.identity.get(pointer, key);
+    
+    blob.identity.getAll(key);
+    
+    blob.identity.getFullAddress(key);  //get text string of full address
+    
+

+//  Events:
+// 'success' : Transaction submitted without error.
+// 'error' : Error submitting transaction.
+// 'proposed' : Advisory proposed status transaction.
+// - A client should expect 0 to multiple results.
+// - Might not get back. The remote might just forward the transaction.
+// - A success could be reverted in final.
+// - local error: other remotes might like it.
+// - malformed error: local server thought it was malformed.
+// - The client should only trust this when talking to a trusted server.
+// 'final' : Final status of transaction.
+// - Only expect a final from dishonest servers after a tesSUCCESS or ter*.
+// 'lost' : Gave up looking for on ledger_closed.
+// 'pending' : Transaction was not found on ledger_closed.
+// 'state' : Follow the state of a transaction.
+//    'client_submitted'     - Sent to remote
+//     |- 'remoteError'      - Remote rejected transaction.
+//      \- 'client_proposed' - Remote provisionally accepted transaction.
+//       |- 'client_missing' - Transaction has not appeared in ledger as expected.
+//       | |\- 'client_lost' - No longer monitoring missing transaction.
+//       |/
+//       |- 'tesSUCCESS'     - Transaction in ledger as expected.
+//       |- 'ter...'         - Transaction failed.
+//       \- 'tec...'         - Transaction claimed fee only.
+//
+// Notes:
+// - All transactions including those with local and malformed errors may be
+//   forwarded anyway.
+// - A malicous server can:
+//   - give any proposed result.
+//     - it may declare something correct as incorrect or something incorrect as correct.

src/js/sjcl/README/INSTALL

@@ -0,0 +1,36 @@
+SJCL comes with a file sjcl.js pre-built.  This default build includes
+all the modules except for sjcl.codec.bytes (because the demo site doesn't
+use it).  All you need to do to install is copy this file to your web
+server and start using it.
+
+SJCL is divided into modules implementing various cryptographic and
+convenience functions.  If you don't need them all for your application,
+you can reconfigure SJCL for a smaller code size.  To do this, you can
+run
+
+./configure --without-all --with-aes --with-sha256 ...
+
+Then type
+
+make
+
+to rebuild sjcl.js.  This will also create a few intermediate files
+core*.js; you can delete these automatically by typing
+
+make sjcl.js tidy
+
+instead.  You will need make, perl, bash and java to rebuild SJCL.
+
+Some of the modules depend on other modules; configure should handle this
+automatically unless you tell it --without-FOO --with-BAR, where BAR
+depends on FOO.  If you do this, configure will yell at you.
+
+SJCL is compressed by stripping comments, shortening variable names, etc.
+You can also pass a --compress argument to configure to change the
+compressor.  By default SJCL uses some perl/sh scripts and Google's
+Closure compressor.
+
+If you reconfigure SJCL, it is recommended that you run the included test
+suite by typing "make test".  If this prints "FAIL" or segfaults, SJCL
+doesn't work; please file a bug.

+ 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 Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in 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.
+
+  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.
+
+                    GNU GENERAL PUBLIC LICENSE
+   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 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 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
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply 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 a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+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:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+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' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+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.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "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.
+
+  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.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  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.
+
+  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.
+
+  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.
+
+  1. Source Code.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  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.
+
+  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.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  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.
+
+  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.
+
+  4. Conveying Verbatim Copies.
+
+  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.
+
+  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.
+
+  5. Conveying Modified Source Versions.
+
+  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:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    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".
+
+    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.
+
+    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.
+
+  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.
+
+  6. Conveying Non-Source Forms.
+
+  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:
+
+    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.
+
+    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.
+
+    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.
+
+    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.
+
+    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.
+
+  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.
+
+  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.
+
+  "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.
+
+  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).
+
+  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.
+
+  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.
+
+  7. Additional Terms.
+
+  "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.
+
+  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.
+
+  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:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    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
+
+    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
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    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.
+
+  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.
+
+  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.
+
+  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.
+
+  8. Termination.
+
+  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).
+
+  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.
+
+  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.
+
+  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.
+
+  9. Acceptance Not Required for Having Copies.
+
+  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.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  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.
+
+  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.
+
+  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.
+
+  11. Patents.
+
+  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".
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  12. No Surrender of Others' Freedom.
+
+  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.
+
+  13. Use with the GNU Affero General Public License.
+
+  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.
+
+  14. Revised Versions of this License.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  15. Disclaimer of Warranty.
+
+  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.
+
+  16. Limitation of Liability.
+
+  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.
+
+  17. Interpretation of Sections 15 and 16.
+
+  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.
+
+                     END OF TERMS AND CONDITIONS
+
+            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
+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.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU 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.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.
