+=== ActivityPub ===
+Contributors: automattic, pfefferle, mediaformat, mattwiebe, akirk, jeherve, nuriapena, cavalierlife
+Tags: OStatus, fediverse, activitypub, activitystream
+Requires at least: 5.5
+Tested up to: 6.5
+Stable tag: 2.3.0
+Requires PHP: 5.6
+License: MIT
+License URI: http://opensource.org/licenses/MIT
+
+The ActivityPub protocol is a decentralized social networking protocol based upon the ActivityStreams 2.0 data format.
+
+== Description ==
+
+Enter the fediverse with **ActivityPub**, broadcasting your blog to a wider audience! Attract followers, deliver updates, and receive comments from a diverse user base of **ActivityPub**\-compliant platforms.
+
+With the ActivityPub plugin installed, your WordPress blog itself function as a federated profile, along with profiles for each author. For instance, if your website is `example.com`, then the blog-wide profile can be found at `@example.com@example.com`, and authors like Jane and Bob would have their individual profiles at `@jane@example.com` and `@bobz@example.com`, respectively.
+
+An example: I give you my Mastodon profile name: `@pfefferle@mastodon.social`. You search, see my profile, and hit follow. Now, any post I make appears in your Home feed. Similarly, with the ActivityPub plugin, you can find and follow Jane's profile at `@jane@example.com`.
+
+Once you follow Jane's `@jane@example.com` profile, any blog post she crafts on `example.com` will land in your Home feed. Simultaneously, by following the blog-wide profile `@example.com@example.com`, you'll receive updates from all authors.
+
+**Note**: if no one follows your author or blog instance, your posts remain unseen. The simplest method to verify the plugin's operation is by following your profile. If you possess a Mastodon profile, initiate by following your new one.
+
+The plugin works with the following tested federated platforms, but there may be more that it works with as well:
+
+* [Mastodon](https://joinmastodon.org/)
+* [Pleroma](https://pleroma.social/)/[Akkoma](https://akkoma.social/)
+* [friendica](https://friendi.ca/)
+* [Hubzilla](https://hubzilla.org/)
+* [Pixelfed](https://pixelfed.org/)
+* [Socialhome](https://socialhome.network/)
+* [Misskey](https://join.misskey.page/)
+* [Firefish](https://joinfirefish.org/) (rebrand of Calckey)
+
+Some things to note:
+
+1. The blog-wide profile is only compatible with sites with rewrite rules enabled. If your site does not have rewrite rules enabled, the author-specific profiles may still work.
+1. Many single-author blogs have chosen to turn off or redirect their author profile pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done to avoid duplicate content with your blog’s home page. If your author page has been deactivated in this way, then ActivityPub author profiles won’t work for you. Instead, you can turn your author profile page back on, and then use the option in your SEO plugin to noindex the author page. This will still resolve duplicate content issues with search engines and will enable ActivityPub author profiles to work.
+1. Once ActivityPub is installed, *only new posts going forward* will be available in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, anyone who follows your site, will only see new posts you publish from that moment on. They will never see previously-published posts in their Home feed. This process is very similar to subscribing to a newsletter. If you subscribe to a newsletter, you will only receive future emails, but not the old archived ones. With ActivityPub, if someone follows your site, they will only receive new blog posts you publish from then on.
+
+So what’s the process?
+
+1. Install the ActivityPub plugin.
+1. Go to the plugin’s settings page and adjust the settings to your liking. Click the Save button when ready.
+1. Make sure your blog’s author profile page is active if you are using author profiles.
+1. Go to Mastodon or any other federated platform, and search for your profile, and follow it. Your new profile will be in the form of either `@your_username@example.com` or `@example.com@example.com`, so that is what you’ll search for.
+1. On your blog, publish a new post.
+1. From Mastodon, check to see if the new post appears in your Home feed.
+
+Please note that it may take up to 15 minutes or so for the new post to show up in your federated feed. This is because the messages are sent to the federated platforms using a delayed cron. This avoids breaking the publishing process for those cases where users might have lots of followers. So please don’t assume that just because you didn’t see it show up right away that something is broken. Give it some time. In most cases, it will show up within a few minutes, and you’ll know everything is working as expected.
+
+== Frequently Asked Questions ==
+
+= tl;dr =
+
+This plugin connects your WordPress blog to popular social platforms like Mastodon, making your posts more accessible to a wider audience. Once installed, your blog can be followed by users on these platforms, allowing them to receive your new posts in their feeds.
+
+= What is the status of this plugin? =
+
+Implemented:
+
+* blog profile pages (JSON representation)
+* author profile pages (JSON representation)
+* custom links
+* functional inbox/outbox
+* follow (accept follows)
+* share posts
+* receive comments/reactions
+* signature verification
+* threaded comments support
+
+To implement:
+
+* replace shortcodes with blocks for layout
+
+= What is "ActivityPub for WordPress" =
+
+*ActivityPub for WordPress* extends WordPress with some Fediverse features, but it does not compete with platforms like Friendica or Mastodon. If you want to run a **decentralized social network**, please use [Mastodon](https://joinmastodon.org/) or [GNU social](https://gnusocial.network/).
+
+= What if you are running your blog in a subdirectory? =
+
+In order for webfinger to work, it must be mapped to the root directory of the URL on which your blog resides.
+
+**Apache**
+
+Add the following to the .htaccess file in the root directory:
+
+	RedirectMatch "^\/\.well-known/(webfinger|nodeinfo|x-nodeinfo2)(.*)$" /blog/.well-known/$1$2
+
+Where 'blog' is the path to the subdirectory at which your blog resides.
+
+**Nginx**
+
+Add the following to the site.conf in sites-available:
+
+	location ~* /.well-known {
+		allow all;
+		try_files $uri $uri/ /blog/?$args;
+	}
+
+Where 'blog' is the path to the subdirectory at which your blog resides.
+
+= What if you are running your blog in a subdirectory, but have a different [wp_siteurl](https://wordpress.org/documentation/article/giving-wordpress-its-own-directory/)? =
+
+In that case you don't need the redirect, because the index.php will take care of that.
+
+= Constants =
+
+The plugin uses PHP Constants to enable, disable or change its default behaviour. Please use them with caution and only if you know what you are doing.
+
+* `ACTIVITYPUB_REST_NAMESPACE` - Change the default Namespace of the REST endpoint. Default: `activitypub/1.0`.
+* `ACTIVITYPUB_EXCERPT_LENGTH` - Change the length of the Excerpt. Default: `400`.
+* `ACTIVITYPUB_SHOW_PLUGIN_RECOMMENDATIONS` - show plugin recommendations in the ActivityPub settings. Default: `true`.
+* `ACTIVITYPUB_MAX_IMAGE_ATTACHMENTS` - Change the number of attachments, that should be federated. Default: `3`.
+* `ACTIVITYPUB_HASHTAGS_REGEXP` - Change the default regex to detect hashtext in a text. Default: `(?:(?<=\s)|(?<=<p>)|(?<=<br>)|^)#([A-Za-z0-9_]+)(?:(?=\s|[[:punct:]]|$))`.
+* `ACTIVITYPUB_USERNAME_REGEXP` - Change the default regex to detect @-replies in a text. Default: `(?:([A-Za-z0-9\._-]+)@((?:[A-Za-z0-9_-]+\.)+[A-Za-z]+))`.
+* `ACTIVITYPUB_CUSTOM_POST_CONTENT` - Change the default template for Activities. Default: `<strong>[ap_title]</strong>\n\n[ap_content]\n\n[ap_hashtags]\n\n[ap_shortlink]`.
+* `ACTIVITYPUB_AUTHORIZED_FETCH` - Enable AUTHORIZED_FETCH. Default: `false`.
+* `ACTIVITYPUB_DISABLE_REWRITES` - Disable auto generation of `mod_rewrite` rules. Default: `false`.
+* `ACTIVITYPUB_DISABLE_INCOMING_INTERACTIONS` - Block incoming replies/comments/likes. Default: `false`.
+* `ACTIVITYPUB_DISABLE_OUTGOING_INTERACTIONS` - Disable outgoing replies/comments/likes. Default: `false`.
+* `ACTIVITYPUB_SHARED_INBOX_FEATURE` - Enable the shared inbox. Default: `false`.
+* `ACTIVITYPUB_SEND_VARY_HEADER` - Enable to send the `Vary: Accept` header. Default: `false`.
+
+= Where can you manage your followers? =
+
+If you have activated the blog user, you will find the list of his followers in the settings under `/wp-admin/options-general.php?page=activitypub&tab=followers`.
+
+The followers of a user can be found in the menu under "Users" -> "Followers" or under `wp-admin/users.php?page=activitypub-followers-list`.
+
+For reasons of data protection, it is not possible to see the followers of other users.

+= Manual Plugin Installation =
+
+There are a few cases when manually installing a WordPress Plugin is appropriate.
+
+* If you wish to control the placement and the process of installing a WordPress Plugin.
+* If your server does not permit automatic installation of a WordPress Plugin.
+* If you want to try the [latest development version](https://github.com/pfefferle/wordpress-activitypub).
+
+Installation of a WordPress Plugin manually requires FTP familiarity and the awareness that you may put your site at risk if you install a WordPress Plugin incompatible with the current version or from an unreliable source.
+
+Backup your site completely before proceeding.
+
+To install a WordPress Plugin manually:
+
+* Download your WordPress Plugin to your desktop.
+    * Download from [the WordPress directory](https://wordpress.org/plugins/activitypub/)
+    * Download from [GitHub](https://github.com/pfefferle/wordpress-activitypub/releases)
+* If downloaded as a zip archive, extract the Plugin folder to your desktop.
+* With your FTP program, upload the Plugin folder to the `wp-content/plugins` folder in your WordPress directory online.
+* Go to [Plugins screen](https://codex.wordpress.org/Administration_Screens#Plugins) and find the newly uploaded Plugin in the list.
+* Click **Activate** to activate it.

+Adds an avatar upload field to user profiles. Generates requested sizes on demand just like Gravatar!
+
+== Description ==
+
+Adds an avatar upload field to user profiles if the current user has media permissions. Generates requested sizes on demand just like Gravatar! Simple and lightweight.
+
+Just edit a user profile, and scroll down to the new "Avatar" field. The plug-in will take care of cropping and sizing!
+
+1. Stores avatars in the "uploads" folder where all of your other media is kept.
+2. Has a simple, native interface.
+3. Fully supports Gravatar and default avatars if no local avatar is set for the user - but also allows you turn off Gravatar.
+4. Generates the requested avatar size on demand (and stores the new size for efficiency), so it looks great, just like Gravatar!
+5. Lets you decide whether lower privilege users (subscribers, contributors) can upload their own avatar.
+6. Enables rating of local avatars, just like Gravatar.
+
+== Installation ==
+
+1. Install easily with the WordPress plugin control panel or manually download the plugin and upload the extracted folder to the `/wp-content/plugins/` directory
+1. Activate the plugin through the 'Plugins' menu in WordPress
+1. If you only want users with file upload capabilities to upload avatars, check the applicable option under Settings > Discussion
+1. Start uploading avatars by editing user profiles!
+
+Use avatars in your theme using WordPress' built in `get_avatar()` function: [http://codex.wordpress.org/Function_Reference/get_avatar](http://codex.wordpress.org/Function_Reference/get_avatar "get_avatar function")
+
+You can also use `get_simple_local_avatar()` (with the same arguments) to retreive local avatars a bit faster, but this will make your theme dependent on this plug-in.
+
+== Frequently Asked Questions ==
+
+= Does Simple Local Avatars collect personal data of website visitors? =
+
+No.  Simple Local Avatars neither collects, stores, nor sends any PII data of visitors or avatar users on the host site or to 10up or other services.
+
+== Screenshots ==
+
+1. Avatar upload field on a user profile page

+
+= 2.1.1 - 2019-05-07 =
+* Fixed: Do not delete avatars just because they don't exist on the local filesystem. This was occasionally dumping avatars when WordPress uploads were stored elsewhere, e.g. a cloud service.
+
+= 2.1 - 2018-10-24 =
+* *New:* All avatar uploads now go into the media library. Don't worry - users without the ability to upload files cannot otherwise see the contents of your media library. This allows local avatars to respect other functionality your site may have around uploaded images, such as external hosting.
+* *New:* REST API support for getting and updating.
+* *New:* Use .org language packs rather than bundling translations.
+* *Fixed:* Avoid an `ArgumentCountError`.
+* *Fixed:* A couple of internationalization issues.
+
+= 2.0 - 2013-06-02 =
+* Choose or upload an avatar from the media library (for users with appropriate capabilities)!
+* Local avatars are rated for appropriateness, just like Gravatar
+* A new setting under Discussion enables administrators to turn off Gravatar (only use local avatars)
+* Delete the local avatar with a single button click (like everywhere else in WordPress)
+* Uploaded avatar file names are appended with the timestamp, addressing browser image caching issues
+* New developer filter for preventing automatic rescaling: simple_local_avatars_dynamic_resize
+* New developer filter for limiting upload size: simple_local_avatars_upload_limit
+* Upgraded functions deprecated since WordPress 3.5
+* Fixed translations not working on front end (although translations are now a bit out of date...)
+* Hungarian translation added (needs further updating again with new version)
+* Assorted refactoring / improvements under the hood
+
+= 1.3.1 - 2011-12-29 =
+* Brazilian Portuguese and Belarusian translations
+* Bug fixes (most notably correct naming of image files based on user display name)
+* Optimization for WordPress 3.2 / 3.3 (substitutes deprecated function)
+
+= 1.3 - 2011-09-22 =
+* Avatar file name saved as "user-display-name_avatar" (or other image extension)
+* Russian localization added
+* Assorted minor code optimizations
+
+= 1.2.4 - 2011-07-02 =
+* Support for front end avatar uploads (e.g. Theme My Profile)
+
+= 1.2.3 - 2011-04-04 =
+* Russian localization
+
+= 1.2.2 - 2011-03-25 =
+* Fix for avatars uploaded pre-1.2.1 having a broken path after upgrade
+
+= 1.2.1 - 2011-01-26 =
+* French localization
+* Simplify uninstall code
+
+= 1.2 - 2011-01-26 =
+* Fix path issues on some IIS servers (resulting in missing avatar images)
+* Fix rare uninstall issues related to deleted avatars
+* Spanish localization
+* Other minor under the hood optimizations
+
+= 1.1.3 - 2011-01-20 =
+* Properly deletes old avatars upon changing avatar
+* Fixes "foreach" warning in debug mode when updating avatar image
+
+= 1.1.2 - 2011-01-18 =
+* Norwegian localization
+
+= 1.1.1 - 2011-01-18 =
+* Italian localization
+
+= 1.1 - 2011-01-18 =
+* All users (regardless of capabilities) can upload avatars by default. To limit avatar uploading to users with upload files capabilities (Authors and above), check the applicable option under Settings > Discussion. This was the default behavior in 1.0.
+* Localization support; German included
+
+= 1.0 - 2011-01-18 =
+* Initial release.
+
+== Upgrade Notice ==
+
+= 2.6.0 =
+**Note that this release bumps the minimum required version of WordPress from 4.6 to 5.7 and PHP from 5.6 to 7.4.**
+
+= 2.1 =
+*Important note:* All avatar uploads now go into the media library. Don't worry - users without the ability to upload files cannot otherwise see the contents of your media library. This allows local avatars to respect other functionality your site may have around uploaded images, such as external hosting.
+
+= 2.0 =
+Upgraded to take advantage of *WordPress 3.5 and newer*. Does not support older versions! This has also *not* been tested with front end profile plug-ins - feedback welcome. Note that several language strings have been added or modified - revised translations would be welcome!
+
+= 1.3.1 =
+Like WordPress 3.2, now *REQUIRES* PHP 5.2 or newer.

+                       Version 2, June 1991
+
+ Copyright (C) 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.
+
+                    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
