and the `value` column in the `config` table need to be `VARCHAR2(4000)`.
#### Using Google Cloud Storage
If you want to deploy PrivateBin in a serverless manner in the Google Cloud, you
can choose the `GoogleCloudStorage` as backend. To use this backend, you create
a GCS bucket and specify the name as the model option `bucket`. Alternatively,
you can set the name through the environment variable `PRIVATEBIN_GCS_BUCKET`.
The default prefix for pastes stored in the bucket is `pastes`. To change the
prefix, specify the option `prefix`.
Google Cloud Storage buckets may be significantly slower than a `FileSystem` or
`Database` backend. The big advantage is that the deployment on Google Cloud
Platform using Google Cloud Run is easy and cheap.
To use the Google Cloud Storage backend you have to install the suggested
library using the command `composer require google/cloud-storage`.

* ADDED: File upload and image display support (optional)
* ADDED: Markdown format support
* ADDED: "bootstrap-compact" template that hides some of the options in a drop down menu to ensure the nav bar fitting on one line on smaller screen sizes
* FIXING: Various usability issues with different screen sizes / device types in the "bootstrap" template
* CHANGED: Instead of having different options to enable and preselect certain formats there is now a generic `[formatter_options]` section where formats can be added to the displayed format drop down menu. A `defaultformatter` can be set, it defaults to "plaintext". The `syntaxhighlighting` configuration got deprecated.
* `zerobin.js` got a major refactoring:
* moved from global namespace into anonymous function
* events are no longer set via "onclick" attributes in the templates, but bound by from JS side
* for simpler maintenance the functions were grouped into objects: zerobin (display logic, event handling), filter (compression,
encryption), i18n (translation, counterpart of i18n.php) and helper (stateless utilities)
* Wiki pages were added to address common topics:
* [Upgrading from ZeroBin 0.19 Alpha](https://github.com/PrivateBin/PrivateBin/wiki/Upgrading-from-ZeroBin-0.19-Alpha)
* [Directory of public PrivateBin servers](https://github.com/PrivateBin/PrivateBin/wiki/PrivateBin-Directory)
* [Translation](https://github.com/PrivateBin/PrivateBin/wiki/Translation)
* [Templates](https://github.com/PrivateBin/PrivateBin/wiki/Templates)
* **0.20 (2015-09-03)**:
* ADDED: Password protected pastes (optional)
* ADDED: configuration options for highlighting, password, discussions, expiration times, rate limiting
* ADDED: JSON-only retrieval of paste incl. discussion, used to be able to refresh paste when posting a comment
* ADDED: bootstrap CSS based template
* CHANGED: "Burn after reading" pastes are now deleted only after the paste was successfully decrypted via callback. This prevents accidental deletion by chatbots following URLs and the like. Usage of a password is suggested to ensure only the desired recipient is able to encrypt it.
* CHANGED: the "opendiscussion" option now only controls if the discussion checkbox is preselected. Use "discussion = false" to disable the discussion feature completely (which also removes the checkbox from the template).
* FIXING: Behaviour of several conflicting configuration options. As a general measure unit tests for 9 of the options and all their possible configurations were added via a unit test generator.
* updated JS libraries: jquery to 1.11.3, sjcl to 1.0.2, base64.js to 2.1.9, deflate to 0.5, inflate to 0.3 and prettify to latest
* generally improved documentation, both inline phpdoc / JSdoc source code documentation, as well as Wiki pages on installation, configuration, development and JSON-API
* **Alpha 0.19 (2013-07-05)**:
* Corrected XSS security flaw which affected IE<10. Other browsers were not affected.
* Corrected spacing display in IE<10.
* **Alpha 0.18 (2013-02-24)**:
* ADDED: The resulting URL is automatically selected after pressing "Send". You just have to press CTRL+C.
* ADDED: Automatic syntax highlighting for 53 languages using highlight.js
* ADDED: "5 minutes" and "1 week" expirations.
* ADDED: "Raw text" button.
* jQuery upgraded to 1.9.1
* sjcl upgraded to GitHub master 2013-02-23
* base64.js upgraded to 1.7
* FIXED: Dates in discussion are now proper local dates.
* ADDED: Robot meta tags in HTML to prevent search engines indexing.
* ADDED: Better json checking (including entropy).
* ADDED: Added version to js/css assets URLs in order to prevent some abusive caches to serve an obsolete version of these files when ZeroBin is upgraded.
* "Burn after reading" option has been moved out of Expiration combo to a separate checkbox. Reason is: You can prevent a read-once paste to be available ad vitam eternam on the net.
* **Alpha 0.17 (2013-02-23)**:
* ADDED: Deletion URL.
* small refactoring.
* improved regex checks.
* larger server alt on installation.
* **Alpha 0.16**:
* FIXED minor php warnings.
* FIXED: zerobin.js reformated and properly commented.
* FIXED: Directory structure re-organized.
* CHANGED: URL shortening button was removed. (It was bad for privacy.)
* **Alpha 0.15 (2012-04-20):**
* FIXED: 2 minor corrections to avoid notices in php log.
* FIXED: Sources converted to UTF-8.
* **Alpha 0.14 (2012-04-20):**
* ADDED: GD presence is checked.
* CHANGED: Traffic limiter data files moved to data/ (→easier rights management)
* ADDED: "Burn after reading" implemented. Opening the URL will display the paste and immediately destroy it on server.
* **Alpha 0.13 (2012-04-18):**
* FIXED: ''imageantialias()'' call removed because it's not really usefull and can be a problem on most hosts (if GD is not compiled in php).
* FIXED: $error not properly initialized in index.php
* **Alpha 0.12 (2012-04-18):**
* **DISCUSSIONS !** Now you can enable discussions on your pastes. Of course, posted comments and nickname are also encrypted and the server cannot see them.
* This feature implies a change in storage format. You will have to delete all previous pastes in your ZeroBin.
* Added [[php:vizhash_gd|Vizhash]] as avatars, so you can match posters IP addresses without revealing them. (Same image = same IP). Of course the IP address cannot be deduced from the Vizhash.
* Remaining time before expiration is now displayed.
* Explicit tags were added to CSS and jQuery selectors (eg. div#aaa instead of #aaa) to speed up browser.
* Better cleaning of the URL (to make sure the key is not broken by some stupid redirection service)
* **Alpha 0.11 (2012-04-12):**
* Automatically ignore parameters (such as &utm_source=...) added //after// the anchor by some stupid Web 2.0 services.
* First public release.
* **Alpha 0.10 (2012-04-12):**
* IE9 does not seem to correctly support ''pre-wrap'' either. Special handling mode activated for all version of IE<10. (Note: **ALL other browsers** correctly support this feature.)
* **Alpha 0.9 (2012-04-11):**
* Oh bummer... IE 8 is as shitty as IE6/7: Its does not seem to support ''white-space:pre-wrap'' correctly. I had to activate the special handling mode. I still have to test IE 9.
* **Alpha 0.8 (2012-04-11):**
* Source code not published yet.
* Interface completely redesigned. Icons added.
* Now properly supports IE6/7 (ugly display, but it works. "Clone" button is disabled though.)
* Added one level of depth for storage directories (This is better for higher load servers).
* php version is now checked (min: 5.2.6)
* Better checks on posted json data on server.
* Added "1 year" expiration.
* URLs are now converted to clickable links. This include http, https, ftp and magnet links.
* Clickable links include ''rel="nofollow"'' to discourage SEO.
* On my public service (http://sebsauvage.net/paste/)
* All data will be deleted (you were warned - this is a test service)
* Default paste expiration is now 1 month to prevent clogging-up my host.

# Installation
**TL;DR:** Download the
[latest release archive](https://github.com/PrivateBin/PrivateBin/releases/latest)
(with the link labelled as "Source code (…)") and extract it in your web hosts
folder where you want to install your PrivateBin instance. We try to provide a
mostly safe default configuration, but we urge you to check the
[security section](#hardening-and-security) below and the
[configuration options](#configuration) to adjust as you see fit.
**NOTE:** See our [FAQ entry on securely downloading release files](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#how-can-i-securely-clonedownload-your-project)
for more information.
**NOTE:** There is a [ansible](https://ansible.com) role by @e1mo available to
install and configure PrivateBin on your server. It's available on
[ansible galaxy](https://galaxy.ansible.com/e1mo/privatebin)
([source code](https://git.sr.ht/~e1mo/ansible-role-privatebin)).
### Minimal Requirements
- PHP version 7.0 or above
- Or PHP version 5.6 AND _one_ of the following sources of cryptographically
safe randomness:

## Hardening and Security
### Changing the Path
In the index.php you can define a different `PATH`. This is useful to secure
your installation. You can move the configuration, data files, templates and PHP
libraries (directories cfg, doc, data, lib, tpl, tst and vendor) outside of your
document root. This new location must still be accessible to your webserver and
PHP process (see also
[open_basedir setting](https://secure.php.net/manual/en/ini.core.php#ini.open-basedir)).
> #### PATH Example
> Your PrivateBin installation lives in a subfolder called "paste" inside of
> your document root. The URL looks like this:
> http://example.com/paste/
>
> The full path of PrivateBin on your webserver is:
> /srv/example.com/htdocs/paste
>
> When setting the path like this:
> define('PATH', '../../secret/privatebin/');
>
> PrivateBin will look for your includes and data here:
> /srv/example.com/secret/privatebin
### Changing the config path only
In situations where you want to keep the PrivateBin static files separate from the
rest of your data, or you want to reuse the installation files on multiple vhosts,
you may only want to change the `conf.php`. In this case, you can set the
`CONFIG_PATH` environment variable to the absolute path to the `conf.php` file.
This can be done in your web server's virtual host config, the PHP config, or in
the index.php, if you choose to customize it.
Note that your PHP process will need read access to the configuration file,
wherever it may be.
> #### CONFIG_PATH example
> Setting the value in an Apache Vhost:
> SetEnv CONFIG_PATH /var/lib/privatebin/conf.php
>
> In a php-fpm pool config:
> env[CONFIG_PATH] = /var/lib/privatebin/conf.php
>
> In the index.php, near the top:
> putenv('CONFIG_PATH=/var/lib/privatebin/conf.php');
### Transport security
When setting up PrivateBin, also set up HTTPS, if you haven't already. Without
HTTPS PrivateBin is not secure, as the JavaScript or WebAssembly files could be
manipulated during transmission. For more information on this, see our
[FAQ entry on HTTPS setup recommendations](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#how-should-i-setup-https).
### File-level permissions
After completing the installation, you should make sure, that other users on the
system cannot read the config file or the `data/` directory, as – depending on
your configuration – potentially sensitive information may be stored in there.
See our [FAQ entry on permissions](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#what-are-the-recommended-file-and-folder-permissions-for-privatebin)
for a detailed guide on how to "harden" access to files and folders.
## Configuration
In the file `cfg/conf.php` you can configure PrivateBin. A `cfg/conf.sample.php`
is provided containing all options and their default values. You can copy it to
`cfg/conf.php` and change it as needed. Alternatively you can copy it anywhere
and set the `CONFIG_PATH` environment variable (see above notes). The config
file is divided into multiple sections, which are enclosed in square brackets.
In the `[main]` section you can enable or disable the discussion feature, set
the limit of stored pastes and comments in bytes. The `[traffic]` section lets
you set a time limit in seconds. Users may not post more often then this limit
to your PrivateBin installation.
More details can be found in the
[configuration documentation](https://github.com/PrivateBin/PrivateBin/wiki/Configuration).
## Advanced installation
### Web server configuration
A `robots.txt` file is provided in the root dir of PrivateBin. It disallows all
robots from accessing your pastes. It is recommend to place it into the root of
your web directory if you have installed PrivateBin in a subdirectory. Make sure
to adjust it, so that the file paths match your installation. Of course also
adjust the file, if you already use a `robots.txt`.
A `.htaccess.disabled` file is provided in the root dir of PrivateBin. It blocks
some known robots and link-scanning bots. If you use Apache, you can rename the
file to `.htaccess` to enable this feature. If you use another webserver, you
have to configure it manually to do the same.
### On using Cloudflare
If you want to use PrivateBin behind Cloudflare, make sure you have disabled the
Rocket loader and unchecked "Javascript" for Auto Minify, found in your domain
settings, under "Speed". More information can be found in our
[FAQ entry on Cloudflare related issues](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#user-content-how-to-make-privatebin-work-when-using-cloudflare-for-ddos-protection).
### Using a Database Instead of Flat Files
In the configuration file the `[model]` and `[model_options]` sections let you
configure your favourite way of storing the pastes and discussions on your
server.
`Filesystem` is the default model, which stores everything in files in the
data folder. This is the recommended setup for most sites on single hosts.
Under high load, in distributed setups or if you are not allowed to store files
locally, you might want to switch to the `Database` model. This lets you
store your data in a database. Basically all databases that are supported by
[PDO](https://secure.php.net/manual/en/book.pdo.php) may be used. Automatic table
creation is provided for `pdo_ibm`, `pdo_informix`, `pdo_mssql`, `pdo_mysql`,
`pdo_oci`, `pdo_pgsql` and `pdo_sqlite`. You may want to provide a table prefix,
if you have to share the PrivateBin database with another application or you want
to use a prefix for
[security reasons](https://security.stackexchange.com/questions/119510/is-using-a-db-prefix-for-tables-more-secure).
The table prefix option is called `tbl`.
> #### Note
> The `Database` model has only been tested with SQLite, MariaDB/MySQL and
> PostgreSQL, although it would not be recommended to use SQLite in a production
> environment. If you gain any experience running PrivateBin on other RDBMS,
> please let us know.
The following GRANTs (privileges) are required for the PrivateBin user in
**MariaDB/MySQL**. In normal operation:
- INSERT, SELECT, DELETE on the paste and comment tables
- SELECT on the config table
If you want PrivateBin to handle table creation (when you create the first paste)
and updates (after you update PrivateBin to a new release), you need to give the
user these additional privileges:
- CREATE, INDEX and ALTER on the database
- INSERT and UPDATE on the config table
For reference or if you want to create the table schema for yourself to avoid
having to give PrivateBin too many permissions (replace `prefix_` with your own
table prefix and create the table schema with your favourite MariaDB/MySQL
client):
```sql
CREATE TABLE prefix_paste (
dataid CHAR(16) NOT NULL,
data MEDIUMBLOB,
postdate INT,
expiredate INT,
opendiscussion INT,
burnafterreading INT,
meta TEXT,
attachment MEDIUMBLOB,
attachmentname BLOB,
PRIMARY KEY (dataid)
);
CREATE TABLE prefix_comment (
dataid CHAR(16),
pasteid CHAR(16),
parentid CHAR(16),
data BLOB,
nickname BLOB,
vizhash BLOB,
postdate INT,
PRIMARY KEY (dataid)
);
CREATE INDEX parent ON prefix_comment(pasteid);
CREATE TABLE prefix_config (
id CHAR(16) NOT NULL, value TEXT, PRIMARY KEY (id)
);
INSERT INTO prefix_config VALUES('VERSION', '1.4.0');
```
In **PostgreSQL**, the `data`, `attachment`, `nickname` and `vizhash` columns
need to be `TEXT` and not `BLOB` or `MEDIUMBLOB`. The key names in brackets,
after `PRIMARY KEY`, need to be removed.
In **Oracle**, the `data`, `attachment`, `nickname` and `vizhash` columns need
to be `CLOB` and not `BLOB` or `MEDIUMBLOB`, the `id` column in the `config`
table needs to be `VARCHAR2(16)` and the `meta` column in the `paste` table
and the `value` column in the `config` table need to be `VARCHAR2(4000)`.
#### Using Google Cloud Storage
If you want to deploy PrivateBin in a serverless manner in the Google Cloud, you
can choose the `GoogleCloudStorage` as backend. To use this backend, you create
a GCS bucket and specify the name as the model option `bucket`. Alternatively,
you can set the name through the environment variable `PRIVATEBIN_GCS_BUCKET`.
The default prefix for pastes stored in the bucket is `pastes`. To change the
prefix, specify the option `prefix`.
Google Cloud Storage buckets may be significantly slower than a `FileSystem` or
`Database` backend. The big advantage is that the deployment on Google Cloud
Platform using Google Cloud Run is easy and cheap.
To use the Google Cloud Storage backend you have to install the suggested
library using the command `composer require google/cloud-storage`.

## GNU General Public License, version 2.0, for rawinflate
_Version 2, June 1991_
_Copyright © 1989, 1991 Free Software Foundation, Inc.,_
_51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA_
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.
### 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.
