-Drupal Examples For Developers: Contributor's Guide
-===================================================
-
-Examples for Developers is a community project.
-
-If you'd like to participate in Examples development, thank you!
-
-If you are new to Drupal or open source in general, have no fear. Examples is
-an easy-going project where you can learn some things about how to work on a
-collaborative project in a friendly environment.
-
-
-Policies
---------
-
-Examples follows the Drupal core process as much as possible.
-
-Contributions thus need to be similar in quality to Drupal core patches.
-Contributions will need to meet the following minimum standards:
-
-### Normal Drupal issue process
-
-Drupal projects use patches related to issues. You should know how to make a
-patch and an interdiff using git. It's fine to develop on github or
-what-have-you, but eventually it has to be a patch that can be reviewed in the
-normal Drupal issue process. See the list of resources for some information on
-how to do do this.
-
-Your patch will also need to be reviewed by someone other than yourself. Learn
-about the review process in the resources section.
-
-### DrupalCI
-
-Examples uses the Drupal automated testing system to verify the applicability of
-patches. See `TESTING.md` for details.
-
-### Drupal coding standards
-
-All code in Examples should adhere to the Drupal core coding standards. Examples
-uses the Drupal Coder project and PHP_CodeSniffer to enforce coding standards.
-Think of this as another test your code must pass. See `STANDARDS.md` for
-details.

-                    GNU GENERAL PUBLIC LICENSE
-                       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
-
-            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.

-Examples for Developers
-=======================
-
-Project site: http://drupal.org/project/examples
-
-Code: https://drupal.org/project/examples/git-instructions
-
-Issues: https://drupal.org/project/issues/examples
-
-What Is This?
--------------
-
-This set of modules is intended to provide working examples of Drupal 8's
-features and APIs.  The modules strive to be simple, well documented and
-modification friendly, in order to help developers quickly learn their inner
-workings.
-
-These examples are meant to teach you about code-level development for Drupal
-8. Some solutions might be better served using a contributed module, so that
-you don't end up having to re-invent the wheel in PHP. When in doubt, look for
-an existing contrib project that already does what you want, and contribute to
-that project.
-
-
-How To Use The Examples
------------------------
-
-There are three main ways to interact with the examples in this project:
-
-1. Enable the modules and use them within Drupal. Not all modules will have
-obvious things to see within your Drupal installation. For instance, while the
-Page and Form API examples will display forms, the Database API example does not
-have much that is visible within Drupal.
-
-2. Read the code. Much effort has gone into making the example code readable,
-not only in terms of the code itself, but also the extensive inline comments
-and documentation blocks.
-
-3. Browse the code and documentation on the web. There are two main places to
-do this:
-
-* https://api.drupal.org/api/examples is the main API site for all of Drupal.
-It has all manner of cross-linked references between the example code and the
-APIs being demonstrated. All of the Doxygen-based comments in the code are
-parsed and made browseable here.
-
-* http://drupalcode.org/project/examples.git allows you to browse the git
-repository for the Examples project.
-
-This project ships with a composer.json file. This is meant to illustrate how
-to provide a composer.json file for a Drupal contrib project. You can read more
-about how to use Composer with Drupal here: https://www.drupal.org/node/2718229
-
-How To Install The Modules
---------------------------
-
-1. The Examples project installs like any other Drupal module. There is extensive
-documentation on how to do this here:
-https://drupal.org/documentation/install/modules-themes/modules-8 But essentially:
-Download the tarball and expand it into the modules/ directory in your Drupal 8
-installation.
-
-2. Within Drupal, enable any Example sub-module you wish to explore in Admin
-menu > Extend.
-
-3. Rebuild access permissions if you are prompted to.
-
-4. Profit!  The links for Examples material will appear in your Tools menu. This
-menu appears on the left sidebar by default. You'll need to reenable it if you
-removed it.
-
-Having seen the behavior of the various example modules, you can move on to
-reading the code, experimenting with it, and hopefully grasp how things work.
-
-If you find a problem, incorrect comment, obsolete or improper code or such,
-please search for an issue about it at http://drupal.org/project/issues/examples
-If there isn't already an issue for it, please create a new one.
-
-Thanks.

-Developing with Coding Standards for Examples for Developers
-============================================================
-
-Examples uses mostly the same coding standards as Drupal core.
-
-If you see a discrepancy between the coding standards tools used by core and
-those used by Examples, please file an issue so that Examples can follow core.
-
-Examples uses the `phpcs` tool to allow for checking PHP coding standards. We
-use the `drupal/coder` project for Drupal-specific coding standards.
-
-We also use `eslint` for JavaScript coding standards, and `csslint` for CSS.
-
-Examples has a `phpcs.xml.dist` file at the root of the project. phpcs uses this
-file to specify the current coding standards 'sniffs' which code in the project
-must pass.
-
-Contributors should install `phpcs` in their local Drupal installation, and then
-use that to run `phpcs` against Examples as part of their development and review
-process. (See details below on how to install and run this tool.)
-
-Contributors can also patch the `phpcs.xml.dist` file itself, in order to fix
-the codebase to pass a given rule or sniff. Patches which do this should be
-limited to a single rule or sniff, in order make the patch easier to review.
-
-Examples also uses the Coder project (`drupal/coder`), which adds additional
-Drupal-specific coding standards. We're currently locked to Coder version
-8.2.8, but this should change to reflect the state of core's coding standards.
-
-Installing phpcs
-----------------
-
-Current versions of Drupal 8 core require phpcs and Coder as dev dependencies.
-That means they're already probably installed in your core vendor/ directory.
-
-We need to tell `phpcs` to use the Drupal coding standard provided by Coder,
-because it isn't configured that way by default.
-
-Like this:
-
-    $ cd my/drupal/root/
-    $ ./vendor/bin/phpcs --config-set installed_paths /full/path/to/drupal/vendor/drupal/coder/coder_sniffer/
-    // phpcs now knows how to find the Drupal standard. You can test it:
-    $ cd core
-    $ ../vendor/bin/phpcs -e --standard=Drupal
-    // Shows you a bunch of Drupal-related sniffs.
-
-Running phpcs
--------------
-
-Now you can run phpcs:
-
-    $ cd modules/examples
-    $ ../../vendor/bin/phpcs -ps
-    // phpcs uses Examples' phpcs.xml.dist to verify coding standards.
-    // -p shows you progress dots.
-    // -s shows you sniff errors in the report.
-
-If there are errors, they can sometimes be fixed with `phpcbf`, which is
-part of the `phpcs` package.
-
-    $ ../../vendor/bin/phpcbf
-    // phpcbf now performs automated fixes.
-
-Always look at the changes to see what `phpcbf` did.
-
-And always re-run `phpcs` in order to discover whether `phpcbf` handled all the
-errors.
-
-Installing eslint
------------------
-
-`eslint` is a node.js tool. You can and probably should install it globally,
-since installing it locally would add files to the examples project.
-Instructions available here: https://www.npmjs.com/package/eslint
-
-Examples has an `.eslintrc` file which defines the JavaScript coding standard.
-This file should be identical to the current Drupal core standard.
-
-Running eslint
---------------
-
-You can run eslint this way:
-
-    $ cd /path/to/examples
-    $ eslint .

-Testing Drupal Examples for Developers
-======================================
-
-The Drupal Examples for Developers project uses DrupalCI testing on drupal.org.
-
-That means: It runs the testbot on every patch that is marked as 'Needs Review.'
-
-Your patch might not get reviewed, and certainly won't get committed unless it
-passes the testbot.
-
-The testbot runs a script that's in your Drupal installation called
-`core/scripts/run-tests.sh`. You can run `run-tests.sh` manually and approximate
-the testbot's behavior.
-
-You can find information on how to run `run-tests.sh` locally here:
-https://www.drupal.org/node/645286
-
-Examples is always targeted to the dev branch of Drupal core for the latest
-release. As of this writing, the latest release of Drupal core is 8.2.5, which
-means development for Examples should be against the Drupal 8.2.x development
-branch. When Drupal 8.3.0 is released, we'll start targeting Examples to 8.3.x,
-and so on.
-
-You should at least run `run-tests.sh` locally against all the changes in your
-patch before uploading it.
-
-Keep in mind that unless you know you're changing behavior that is being tested
-for, the tests are not at fault. :-)
-
-Note also that, currently, using the `phpunit` tool under Drupal 8 will not find
-PHPUnit-based tests in submodules, such as phpunit_example. There is no
-suggested workaround for this, since there is no best practice to demonstrate as
-an example. There is, however, this issue in core:
-https://www.drupal.org/node/2499239
-
-How To Run The Tests In The Drupal UI
--------------------------------------
-
-Generally, you should run tests from the command line. This is generally easier
-than using Drupal's testing UI. However, here's how you can do it that way:
-
-Enable the Testing module.
-
-Visit the test list page at `admin/config/development/testing`.
-
-Since the tests are organized by module, you can search for a module name and
-get all the tests for that module. For instance, type in 'node_type_example' for
-all the tests related to that module.
-
-Click the check boxes next to the tests you want to run. If you find this
-tedious, it's time to learn to use the command line. :-)
-
-Click 'Run Tests.' You're now running the tests.
-
-Step-by-step: How To Run The Tests.
------------------------------------
-
-Begin with an installed Drupal codebase. Make a codebase, set up the database,
-etc. Note that you can use an existing Drupal instance but the best practice is
-to start fresh. Something not working right? Try a new installation.
-
-Use the dev branch of core for the latest release of Drupal. As of this writing,
-it's 8.2.x. When Drupal 8.3.0 is released, we'll target 8.3.x.
-
-Open the terminal window and move to the root directory of the Drupal
-installation:
-
-	$ cd path/to/drupal
-
-Put Examples into the `modules/` folder of the Drupal installation. If you are
-doing development on Examples, you should have already checked out the git
-repository into `modules/`, like this:
-
-	$ git clone --branch 8.x-1.x https://git.drupal.org/project/examples.git modules/examples
-
-Now you can run `run-tests.sh`, which, despite having a `.sh` suffix is not a
-shell script. It's a PHP script.
-
-You'll use the `--directory` option to have the test runner scan the Examples
-module directory for tests.
-
-Also, importantly, if your test site has its own URL, you'll need to supply that
-with the `--url` option. For instance, under MAMP, you must specify
-`--url http://localhost:8888/`.
-
-You can also use `--concurrency` to speed up the test run, and `--browser` to
-see detailed test results in a web browser instead of just text output in the
-terminal.
-
-	$ php ./core/scripts/run-tests.sh --browser --concurrency 10 --url http://localhost:8888/ --directory modules/examples
-
-This should run all the tests present in Examples. If you add a test and it
-doesn't appear in the list of tests to run, then you'll need to double-check
-that it's in the proper test namespace and that the class name (and thus the
-file name) ends in Test.
-
-What Tests Should An Example Module Have?
-------------------------------------------
-
-Examples has a checklist for each module:
-https://www.drupal.org/node/2209627
-
-The reason we care about these tests is that we want the documentation
-of these APIs to be correct. If Core changes APIs, we want our tests to
-fail so that we know our documentation is incorrect.
-
-Our list of required tests includes:
-* Functional tests which verifies a 200 result for each route/path defined by
-    the module.
-* Functional tests of permission-based restrictions.
-* Functional tests which submit forms and verify that they behave as
-    expected.
-* Unit tests of unit-testable code.
-* Other. More. Better.

- * Implement a Config Entity.
- *
- * This module demonstrates implementing a Config Entity.
- *
- * This is an example of a simple configuration entity, the kind you might
- * create to store administrator-defined objects like blocks or views.
- *
- * In this module we define a configuration entity named 'Robot'. The entity
- * has a unique ID (also called a machine name), a human-readable label used
- * for display, and a universally unique identifier. You can create new robots
- * by navigating to &lt;your_site_root&gt;/examples/config_entity_example. A
- * default robot, "marvin", is included with the module.
- *
- * What's special about a Configuration Entity?
- *
- * Configuration entities are entities just like content entities. The key
- * difference is where the data is stored. Content entities are stored in the
- * database. Configuration entities are stored in *.yml files, typically under
- * &lt;your_site_root&gt;/sites/default/files/config_&lt;unique_id&gt;.
- *
- * Another key difference with configuration entities is the expectation they
- * are created by administrators, and not end users. As files, configuration
- * entities can be added to a version control system.
- *
- * Originally based on code from blog post at
- * http://previousnext.com.au/blog/understanding-drupal-8s-config-entities

- * This module demonstrates implementing a content entity.
- *
- * Entity API is the API that stores pieces of content and configuration for
- * Drupal core. For instance, if you've encountered node content types, you've
- * encountered entities of type 'node.'
- *
- * This example implements the Entity API so that we have an entity type usable
- * by the user which you might think of as specialized nodes, but which are
- * different from nodes. These entities are called Contact, and are known
- * internally by the machine name content_entity_example_contact.
- *
- * Contact is a fieldable content entity used to hold structured information
- * without the overhead of using a node content type. 'Fieldable' means you can
- * attach fields to it, like you can with nodes. It is defined programmatically
- * (completely in code). We will show the main techniques to handle and expose
- * the contents of this entity type.
- *
- * The Contact entity will demonstrate the main tasks for an entity:
- * - define
- * - save
- * - load
- * - view
- * - edit
- * - delete
- * - control access
- *
- * Where ever possible, we use the amazing tools built into D8 natively.

- * This is the main definition of the entity type. From it, an entityType is

- *   called when a route lists an '_entity_view' default for the entityType
- *   (see routing.yml for details. The view can be manipulated by using the
- *   standard drupal tools in the settings.

- *   entityListBuilder to control the presentation.
- *   If there is a view available for this entity from the views module, it
- *   overrides the list builder. @todo: any view? naming convention?
- *
- * - form: We derive our own forms to add functionality like additional fields,
- *   redirects etc. These forms are called when the routing list an
- *   '_entity_form' default for the entityType. Depending on the suffix
- *   (.add/.edit/.delete) in the route, the correct form is called.
- *
- * - access: Our own accessController where we determine access rights based on
- *   permissions.
- *
- * More properties:
- *
- *  - base_table: Define the name of the table used to store the data. Make sure
- *    it is unique. The schema is automatically determined from the
- *    BaseFieldDefinitions below. The table is automatically created during
- *    installation.
- *
- *  - fieldable: Can additional fields be added to the entity via the GUI?
- *    Analog to content types.
- *
- *  - entity_keys: How to access the fields. Analog to 'nid' or 'uid'.
- *
- *  - links: Provide links to do standard tasks. The 'edit-form' and
- *    'delete-form' links are added to the list built by the
- *    entityListController. They will show up as action buttons in an additional
- *    column.
- *
- * There are many more properties to be used in an entity type definition. For
- * a complete overview, please refer to the '\Drupal\Core\Entity\EntityType'
- * class definition.
- *
- * The following construct is the actual definition of the entity type which
- * is read and cached. Don't forget to clear cache after changes.
- *
- * @ContentEntityType(
- *   id = "content_entity_example_contact",
- *   label = @Translation("Contact entity"),
- *   handlers = {
- *     "view_builder" = "Drupal\Core\Entity\EntityViewBuilder",
- *     "list_builder" = "Drupal\content_entity_example\Entity\Controller\ContactListBuilder",
- *     "form" = {
- *       "add" = "Drupal\content_entity_example\Form\ContactForm",
- *       "edit" = "Drupal\content_entity_example\Form\ContactForm",
- *       "delete" = "Drupal\content_entity_example\Form\ContactDeleteForm",
- *     },
- *     "access" = "Drupal\content_entity_example\ContactAccessControlHandler",
- *   },
- *   list_cache_contexts = { "user" },
- *   base_table = "contact",
- *   admin_permission = "administer content_entity_example entity",
- *   entity_keys = {
- *     "id" = "id",
- *     "label" = "name",
- *     "uuid" = "uuid"
- *   },
- *   links = {
- *     "canonical" = "/content_entity_example_contact/{content_entity_example_contact}",
- *     "edit-form" = "/content_entity_example_contact/{content_entity_example_contact}/edit",
- *     "delete-form" = "/contact/{content_entity_example_contact}/delete",
- *     "collection" = "/content_entity_example_contact/list"
- *   },
- *   field_ui_base_route = "content_entity_example.contact_settings",
- * )
- *
- * The 'links' above are defined by their path. For core to find the
- * corresponding route, the route name must follow the correct pattern:
- *
- * entity.<entity-name>.<link-name> (replace dashes with underscores)
- * Example: 'entity.content_entity_example_contact.canonical'
- *
- * See routing file above for the corresponding implementation
- *
- * The Contact class defines methods and fields for the contact entity.
- *
- * Being derived from the ContentEntityBase class, we can override the methods
- * we want. In our case we want to provide access to the standard fields about
- * creation and changed time stamps.
- *
- * Our interface (see ContactInterface) also exposes the EntityOwnerInterface.
- * This allows us to provide methods for setting and providing ownership
- * information.
- *
- * The most important part is the definitions of the field properties for this
- * entity type. These are of the same type as fields added through the GUI, but
- * they can by changed in code. In the definition we can define if the user with
- * the rights privileges can influence the presentation (view, edit) of each
- * field.
- *
- * The class also uses the EntityChangedTrait trait which allows it to record
- * timestamps of save operations.
