+Introduction
+============
+
+This book is about *Symfony YAML*, a PHP library part of the Symfony
+Components project. Its official website is at
+http://components.symfony-project.org/yaml/.
+
+>**SIDEBAR**
+>About the Symfony Components
+>
+>[Symfony Components](http://components.symfony-project.org/) are
+>standalone PHP classes that can be easily used in any
+>PHP project. Most of the time, they have been developed as part of the
+>[Symfony framework](http://www.symfony-project.org/), and decoupled from the
+>main framework later on. You don't need to use the Symfony MVC framework to use
+>the components.
+
+What is it?
+-----------
+
+Symfony YAML is a PHP library that parses YAML strings and converts them to
+PHP arrays. It can also converts PHP arrays to YAML strings.
+
+[YAML](http://www.yaml.org/), YAML Ain't Markup Language, is a human friendly
+data serialization standard for all programming languages. YAML is a great
+format for your configuration files. YAML files are as expressive as XML files
+and as readable as INI files.
+
+### Easy to use
+
+There is only one archive to download, and you are ready to go. No
+configuration, No installation. Drop the files in a directory and start using
+it today in your projects.
+
+### Open-Source
+
+Released under the MIT license, you are free to do whatever you want, even in
+a commercial environment. You are also encouraged to contribute.
+
+
+### Used by popular Projects
+
+Symfony YAML was initially released as part of the symfony framework, one of
+the most popular PHP web framework. It is also embedded in other popular
+projects like PHPUnit or Doctrine.
+
+### Documented
+
+Symfony YAML is fully documented, with a dedicated online book, and of course
+a full API documentation.
+
+### Fast
+
+One of the goal of Symfony YAML is to find the right balance between speed and
+features. It supports just the needed feature to handle configuration files.
+
+### Unit tested
+
+The library is fully unit-tested. With more than 400 unit tests, the library
+is stable and is already used in large projects.
+
+### Real Parser
+
+It sports a real parser and is able to parse a large subset of the YAML
+specification, for all your configuration needs. It also means that the parser
+is pretty robust, easy to understand, and simple enough to extend.
+
+### Clear error messages
+
+Whenever you have a syntax problem with your YAML files, the library outputs a
+helpful message with the filename and the line number where the problem
+occurred. It eases the debugging a lot.
+
+### Dump support
+
+It is also able to dump PHP arrays to YAML with object support, and inline
+level configuration for pretty outputs.
+
+### Types Support
+
+It supports most of the YAML built-in types like dates, integers, octals,
+booleans, and much more...
+
+
+### Full merge key support
+
+Full support for references, aliases, and full merge key. Don't repeat
+yourself by referencing common configuration bits.
+
+### PHP Embedding
+
+YAML files are dynamic. By embedding PHP code inside a YAML file, you have
+even more power for your configuration files.
+
+Installation
+------------
+
+Symfony YAML can be installed by downloading the source code as a
+[tar](http://github.com/fabpot/yaml/tarball/master) archive or a
+[zip](http://github.com/fabpot/yaml/zipball/master) one.
+
+To stay up-to-date, you can also use the official Subversion
+[repository](http://svn.symfony-project.com/components/yaml/).
+
+If you are a Git user, there is an official
+[mirror](http://github.com/fabpot/yaml), which is updated every 10 minutes.
+
+If you prefer to install the component globally on your machine, you can use
+the symfony [PEAR](http://pear.symfony-project.com/) channel server.
+
+Support
+-------
+
+Support questions and enhancements can be discussed on the
+[mailing-list](http://groups.google.com/group/symfony-components).
+
+If you find a bug, you can create a ticket at the symfony
+[trac](http://trac.symfony-project.org/newticket) under the *YAML* component.

+Using Symfony YAML
+==================
+
+The Symfony YAML library is very simple and consists of two main classes: one
+to parse YAML strings (`sfYamlParser`), and the other to dump a PHP array to
+a YAML string (`sfYamlDumper`).
+
+On top of these two core classes, the main `sfYaml` class acts as a thin
+wrapper and simplifies common uses.
+
+Reading YAML Files
+------------------
+
+The `sfYamlParser::parse()` method parses a YAML string and converts it to a
+PHP array:
+
+    [php]
+    $yaml = new sfYamlParser();
+    $value = $yaml->parse(file_get_contents('/path/to/file.yaml'));
+
+If an error occurs during parsing, the parser throws an exception indicating
+the error type and the line in the original YAML string where the error
+occurred:
+
+    [php]
+    try
+    {
+      $value = $yaml->parse(file_get_contents('/path/to/file.yaml'));
+    }
+    catch (InvalidArgumentException $e)
+    {
+      // an error occurred during parsing
+      echo "Unable to parse the YAML string: ".$e->getMessage();
+    }
+
+>**TIP**
+>As the parser is reentrant, you can use the same parser object to load
+>different YAML strings.
+
+When loading a YAML file, it is sometimes better to use the `sfYaml::load()`
+wrapper method:
+
+    [php]
+    $loader = sfYaml::load('/path/to/file.yml');
+
+The `sfYaml::load()` static method takes a YAML string or a file containing
+YAML. Internally, it calls the `sfYamlParser::parse()` method, but with some
+added bonuses:
+
+  * It executes the YAML file as if it was a PHP file, so that you can embed
+    PHP commands in YAML files;
+
+  * When a file cannot be parsed, it automatically adds the file name to the
+    error message, simplifying debugging when your application is loading
+    several YAML files.
+
+Writing YAML Files
+------------------
+
+The `sfYamlDumper` dumps any PHP array to its YAML representation:
+
+    [php]
+    $array = array('foo' => 'bar', 'bar' => array('foo' => 'bar', 'bar' => 'baz'));
+
+    $dumper = new sfYamlDumper();
+    $yaml = $dumper->dump($array);
+    file_put_contents('/path/to/file.yaml', $yaml);
+
+>**NOTE**
+>Of course, the Symfony YAML dumper is not able to dump resources. Also,
+>even if the dumper is able to dump PHP objects, it is to be considered
+>an alpha feature.
+
+If you only need to dump one array, you can use the `sfYaml::dump()` static
+method shortcut:
+
+    [php]
+    $yaml = sfYaml::dump($array, $inline);
+
+The YAML format supports two kind of representation for arrays, the expanded
+one, and the inline one. By default, the dumper uses the inline
+representation:
+
+    [yml]
+    { foo: bar, bar: { foo: bar, bar: baz } }
+
+The second argument of the `dump()` method customizes the level at which the
+output switches from the expanded representation to the inline one:
+
+    [php]
+    echo $dumper->dump($array, 1);
+
+-
+
+    [yml]
+    foo: bar
+    bar: { foo: bar, bar: baz }
+
+-
+
+    [php]
+    echo $dumper->dump($array, 2);
+
+-
+
+    [yml]
+    foo: bar
+    bar:
+      foo: bar
+      bar: baz

+The YAML Format
+===============
+
+According to the official [YAML](http://yaml.org/) website, YAML is "a human
+friendly data serialization standard for all programming languages".
+
+Even if the YAML format can describe complex nested data structure, this
+chapter only describes the minimum set of features needed to use YAML as a
+configuration file format.
+
+YAML is a simple language that describes data. As PHP, it has a syntax for
+simple types like strings, booleans, floats, or integers. But unlike PHP, it
+makes a difference between arrays (sequences) and hashes (mappings).
+
+Scalars
+-------
+
+The syntax for scalars is similar to the PHP syntax.
+
+### Strings
+
+    [yml]
+    A string in YAML
+
+-
+
+    [yml]
+    'A singled-quoted string in YAML'
+
+>**TIP**
+>In a single quoted string, a single quote `'` must be doubled:
+>
+>     [yml]
+>     'A single quote '' in a single-quoted string'
+
+    [yml]
+    "A double-quoted string in YAML\n"
+
+Quoted styles are useful when a string starts or ends with one or more
+relevant spaces.
+
+>**TIP**
+>The double-quoted style provides a way to express arbitrary strings, by
+>using `\` escape sequences. It is very useful when you need to embed a
+>`\n` or a unicode character in a string.
+
+When a string contains line breaks, you can use the literal style, indicated
+by the pipe (`|`), to indicate that the string will span several lines. In
+literals, newlines are preserved:
+
+    [yml]
+    |
+      \/ /| |\/| |
+      / / | |  | |__
+
+Alternatively, strings can be written with the folded style, denoted by `>`,
+where each line break is replaced by a space:
+
+    [yml]
+    >
+      This is a very long sentence
+      that spans several lines in the YAML
+      but which will be rendered as a string
+      without carriage returns.
+
+>**NOTE**
+>Notice the two spaces before each line in the previous examples. They
+>won't appear in the resulting PHP strings.

+### Nulls
+
+Nulls in YAML can be expressed with `null` or `~`.
+
+### Booleans
+
+Booleans in YAML are expressed with `true` and `false`.
+
+>**NOTE**
+>The symfony YAML parser also recognize `on`, `off`, `yes`, and `no` but
+>it is strongly discouraged to use them as it has been removed from the
+>1.2 YAML specifications.
+
+### Dates
+
+YAML uses the ISO-8601 standard to express dates:
+
+    [yml]
+    2001-12-14t21:59:43.10-05:00
+
+-
+
+    [yml]
+    # simple date
+    2002-12-14
+
+Collections
+-----------
+
+A YAML file is rarely used to describe a simple scalar. Most of the time, it
+describes a collection. A collection can be a sequence or a mapping of
+elements. Both sequences and mappings are converted to PHP arrays.
+
+Sequences use a dash followed by a space (`- `):
+
+    [yml]
+    - PHP
+    - Perl
+    - Python
+
+The previous YAML file is equivalent to the following PHP code:
+
+    [php]
+    array('PHP', 'Perl', 'Python');
+
+Mappings use a colon followed by a space (`: `) to mark each key/value pair:
+
+    [yml]
+    PHP: 5.2
+    MySQL: 5.1
+    Apache: 2.2.20
+
+which is equivalent to this PHP code:
+
+    [php]
+    array('PHP' => 5.2, 'MySQL' => 5.1, 'Apache' => '2.2.20');
+
+>**NOTE**
+>In a mapping, a key can be any valid scalar.
+
+The number of spaces between the colon and the value does not matter:
+
+    [yml]
+    PHP:    5.2
+    MySQL:  5.1
+    Apache: 2.2.20
+
+YAML uses indentation with one or more spaces to describe nested collections:
+
+    [yml]
+    "symfony 1.0":
+      PHP:    5.0
+      Propel: 1.2
+    "symfony 1.2":
+      PHP:    5.2
+      Propel: 1.3
+
+The following YAML is equivalent to the following PHP code:
+
+    [php]
+    array(
+      'symfony 1.0' => array(
+        'PHP'    => 5.0,
+        'Propel' => 1.2,
+      ),
+      'symfony 1.2' => array(
+        'PHP'    => 5.2,
+        'Propel' => 1.3,
+      ),
+    );
+
+There is one important thing you need to remember when using indentation in a
+YAML file: *Indentation must be done with one or more spaces, but never with
+tabulations*.
+
+You can nest sequences and mappings as you like:
+
+    [yml]
+    'Chapter 1':
+      - Introduction
+      - Event Types
+    'Chapter 2':
+      - Introduction
+      - Helpers
+
+YAML can also use flow styles for collections, using explicit indicators
+rather than indentation to denote scope.
+
+A sequence can be written as a comma separated list within square brackets
+(`[]`):
+
+    [yml]
+    [PHP, Perl, Python]
+
+A mapping can be written as a comma separated list of key/values within curly
+braces (`{}`):
+
+    [yml]
+    { PHP: 5.2, MySQL: 5.1, Apache: 2.2.20 }
+
+You can mix and match styles to achieve a better readability:
+
+    [yml]
+    'Chapter 1': [Introduction, Event Types]
+    'Chapter 2': [Introduction, Helpers]
+
+-
+
+    [yml]
+    "symfony 1.0": { PHP: 5.0, Propel: 1.2 }
+    "symfony 1.2": { PHP: 5.2, Propel: 1.3 }
+
+Comments
+--------
+
+Comments can be added in YAML by prefixing them with a hash mark (`#`):
+
+    [yml]
+    # Comment on a line
+    "symfony 1.0": { PHP: 5.0, Propel: 1.2 } # Comment at the end of a line
+    "symfony 1.2": { PHP: 5.2, Propel: 1.3 }
+
+>**NOTE**
+>Comments are simply ignored by the YAML parser and do not need to be
+>indented according to the current level of nesting in a collection.
+
+Dynamic YAML files
+------------------
+
+In symfony, a YAML file can contain PHP code that is evaluated just before the
+parsing occurs:
+
+    [php]
+    1.0:
+      version: <?php echo file_get_contents('1.0/VERSION')."\n" ?>
+    1.1:
+      version: "<?php echo file_get_contents('1.1/VERSION') ?>"
+
+Be careful to not mess up with the indentation. Keep in mind the following
+simple tips when adding PHP code to a YAML file:
+
+ * The `<?php ?>` statements must always start the line or be embedded in a
+   value.
+
+ * If a `<?php ?>` statement ends a line, you need to explicitly output a new
+   line ("\n").
+
+<div class="pagebreak"></div>
+
+A Full Length Example

+
+  Nothing in this License is intended to reduce, limit, or restrict any uses free from copyright or rights arising from limitations or exceptions that are provided for in connection with the copyright protection under copyright law or other applicable laws.
+
+3. License Grant
+
+  Subject to the terms and conditions of this License, Licensor hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the duration of the applicable copyright) license to exercise the rights in the Work as stated below:
+
+  a. to Reproduce the Work, to incorporate the Work into one or more Collections, and to Reproduce the Work as incorporated in the Collections;
+
+  b. to create and Reproduce Adaptations provided that any such Adaptation, including any translation in any medium, takes reasonable steps to clearly label, demarcate or otherwise identify that changes were made to the original Work. For example, a translation could be marked "The original work was translated from English to Spanish," or a modification could indicate "The original work has been modified.";
+
+  c. to Distribute and Publicly Perform the Work including as incorporated in Collections; and,
+
+  d. to Distribute and Publicly Perform Adaptations.
+
+  e. For the avoidance of doubt:
+
+    i. **Non-waivable Compulsory License Schemes**. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme cannot be waived, the Licensor reserves the exclusive right to collect such royalties for any exercise by You of the rights granted under this License;
+
+    ii. **Waivable Compulsory License Schemes**. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme can be waived, the Licensor waives the exclusive right to collect such royalties for any exercise by You of the rights granted under this License; and,
+
+    iii. **Voluntary License Schemes**. The Licensor waives the right to collect royalties, whether individually or, in the event that the Licensor is a member of a collecting society that administers voluntary licensing schemes, via that society, from any exercise by You of the rights granted under this License.
+
+  The above rights may be exercised in all media and formats whether now known or hereafter devised. The above rights include the right to make such modifications as are technically necessary to exercise the rights in other media and formats. Subject to Section 8(f), all rights not expressly granted by Licensor are hereby reserved.
+
+4. Restrictions
+
+  The license granted in Section 3 above is expressly made subject to and limited by the following restrictions:
+
+  a. You may Distribute or Publicly Perform the Work only under the terms of this License. You must include a copy of, or the Uniform Resource Identifier (URI) for, this License with every copy of the Work You Distribute or Publicly Perform. You may not offer or impose any terms on the Work that restrict the terms of this License or the ability of the recipient of the Work to exercise the rights granted to that recipient under the terms of the License. You may not sublicense the Work. You must keep intact all notices that refer to this License and to the disclaimer of warranties with every copy of the Work You Distribute or Publicly Perform. When You Distribute or Publicly Perform the Work, You may not impose any effective technological measures on the Work that restrict the ability of a recipient of the Work from You to exercise the rights granted to that recipient under the terms of the License. This Section 4(a) applies to the Work as incorporated in a Collection, but this does not require the Collection apart from the Work itself to be made subject to the terms of this License. If You create a Collection, upon notice from any Licensor You must, to the extent practicable, remove from the Collection any credit as required by Section 4(c), as requested. If You create an Adaptation, upon notice from any Licensor You must, to the extent practicable, remove from the Adaptation any credit as required by Section 4(c), as requested.
+
+  b. You may Distribute or Publicly Perform an Adaptation only under the terms of: (i) this License; (ii) a later version of this License with the same License Elements as this License; (iii) a Creative Commons jurisdiction license (either this or a later license version) that contains the same License Elements as this License (e.g., Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible License. If you license the Adaptation under one of the licenses mentioned in (iv), you must comply with the terms of that license. If you license the Adaptation under the terms of any of the licenses mentioned in (i), (ii) or (iii) (the "Applicable License"), you must comply with the terms of the Applicable License generally and the following provisions: (I) You must include a copy of, or the URI for, the Applicable License with every copy of each Adaptation You Distribute or Publicly Perform; (II) You may not offer or impose any terms on the Adaptation that restrict the terms of the Applicable License or the ability of the recipient of the Adaptation to exercise the rights granted to that recipient under the terms of the Applicable License; (III) You must keep intact all notices that refer to the Applicable License and to the disclaimer of warranties with every copy of the Work as included in the Adaptation You Distribute or Publicly Perform; (IV) when You Distribute or Publicly Perform the Adaptation, You may not impose any effective technological measures on the Adaptation that restrict the ability of a recipient of the Adaptation from You to exercise the rights granted to that recipient under the terms of the Applicable License. This Section 4(b) applies to the Adaptation as incorporated in a Collection, but this does not require the Collection apart from the Adaptation itself to be made subject to the terms of the Applicable License.
+
+  c. If You Distribute, or Publicly Perform the Work or any Adaptations or Collections, You must, unless a request has been made pursuant to Section 4(a), keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing: (i) the name of the Original Author (or pseudonym, if applicable) if supplied, and/or if the Original Author and/or Licensor designate another party or parties (e.g., a sponsor institute, publishing entity, journal) for attribution ("Attribution Parties") in Licensor's copyright notice, terms of service or by other reasonable means, the name of such party or parties; (ii) the title of the Work if supplied; (iii) to the extent reasonably practicable, the URI, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and (iv) , consistent with Ssection 3(b), in the case of an Adaptation, a credit identifying the use of the Work in the Adaptation (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). The credit required by this Section 4(c) may be implemented in any reasonable manner; provided, however, that in the case of a Adaptation or Collection, at a minimum such credit will appear, if a credit for all contributing authors of the Adaptation or Collection appears, then as part of these credits and in a manner at least as prominent as the credits for the other contributing authors. For the avoidance of doubt, You may only use the credit required by this Section for the purpose of attribution in the manner set out above and, by exercising Your rights under this License, You may not implicitly or explicitly assert or imply any connection with, sponsorship or endorsement by the Original Author, Licensor and/or Attribution Parties, as appropriate, of You or Your use of the Work, without the separate, express prior written permission of the Original Author, Licensor and/or Attribution Parties.
+
+  d. Except as otherwise agreed in writing by the Licensor or as may be otherwise permitted by applicable law, if You Reproduce, Distribute or Publicly Perform the Work either by itself or as part of any Adaptations or Collections, You must not distort, mutilate, modify or take other derogatory action in relation to the Work which would be prejudicial to the Original Author's honor or reputation. Licensor agrees that in those jurisdictions (e.g. Japan), in which any exercise of the right granted in Section 3(b) of this License (the right to make Adaptations) would be deemed to be a distortion, mutilation, modification or other derogatory action prejudicial to the Original Author's honor and reputation, the Licensor will waive or not assert, as appropriate, this Section, to the fullest extent permitted by the applicable national law, to enable You to reasonably exercise Your right under Section 3(b) of this License (right to make Adaptations) but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+  UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability
+
+  EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+  a. This License and the rights granted hereunder will terminate automatically upon any breach by You of the terms of this License. Individuals or entities who have received Adaptations or Collections from You under this License, however, will not have their licenses terminated provided such individuals or entities remain in full compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of this License.
+
+  b. Subject to the above terms and conditions, the license granted here is perpetual (for the duration of the applicable copyright in the Work). Notwithstanding the above, Licensor reserves the right to release the Work under different license terms or to stop distributing the Work at any time; provided, however that any such election will not serve to withdraw this License (or any other license that has been, or is required to be, granted under the terms of this License), and this License will continue in full force and effect unless terminated as stated above.
+
+8. Miscellaneous
+
+  a. Each time You Distribute or Publicly Perform the Work or a Collection, the Licensor offers to the recipient a license to the Work on the same terms and conditions as the license granted to You under this License.
+
+  b. Each time You Distribute or Publicly Perform an Adaptation, Licensor offers to the recipient a license to the original Work on the same terms and conditions as the license granted to You under this License.
+
+  c. If any provision of this License is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this License, and without further action by the parties to this agreement, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
+
+  d. No term or provision of this License shall be deemed waived and no breach consented to unless such waiver or consent shall be in writing and signed by the party to be charged with such waiver or consent.
+
+  e. This License constitutes the entire agreement between the parties with respect to the Work licensed here. There are no understandings, agreements or representations with respect to the Work not specified here. Licensor shall not be bound by any additional provisions that may appear in any communication from You. This License may not be modified without the mutual written agreement of the Licensor and You.
+
+  f. The rights granted under, and the subject matter referenced, in this License were drafted utilizing the terminology of the Berne Convention for the Protection of Literary and Artistic Works (as amended on September 28, 1979), the Rome Convention of 1961, the WIPO Copyright Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and the Universal Copyright Convention (as revised on July 24, 1971). These rights and subject matter take effect in the relevant jurisdiction in which the License terms are sought to be enforced according to the corresponding provisions of the implementation of those treaty provisions in the applicable national law. If the standard suite of rights granted under applicable copyright law includes additional rights not granted under this License, such additional rights are deemed to be included in the License; this License is not intended to restrict the license of any rights under applicable law.

Creative Commons will not be liable to You or any party on any legal theory for any damages whatsoever, including without limitation any general, special, incidental or consequential damages arising in connection to this license. Notwithstanding the foregoing two (2) sentences, if Creative Commons has expressly identified itself as the Licensor hereunder, it shall have all rights and obligations of Licensor.

+test: Simple Alias Example
+brief: >
+    If you need to refer to the same item of data twice,
+    you can give that item an alias.  The alias is a plain
+    string, starting with an ampersand.  The item may then
+    be referred to by the alias throughout your document
+    by using an asterisk before the name of the alias.
+    This is called an anchor.
+yaml: |
+    - &showell Steve
+    - Clark
+    - Brian
+    - Oren
+    - *showell
+php: |
+    array('Steve', 'Clark', 'Brian', 'Oren', 'Steve')

+test: Alias of a Mapping
+brief: >
+    An alias can be used on any item of data, including

+        Meat: pork
+        Starch: potato

+test: Simple Sequence 
+brief: | 
+    You can specify a list in YAML by placing each 
+    member of the list on a new line with an opening 
+    dash. These lists are called sequences. 
+yaml: | 
+    - apple

+    - carrot 
+php: |
+    array('apple', 'banana', 'carrot')
+--- 
+test: Nested Sequences 
+brief: | 
+    You can include a sequence within another 
+    sequence by giving the sequence an empty 
+    dash, followed by an indented list.

+     - bar 
+     - baz

+brief: | 
+    Sequences can be nested even deeper, with each 
+    level of indentation representing a level of 
+    depth.

+--- 
+test: Simple Mapping 
+brief: | 
+    You can add a keyed list (also known as a dictionary or 
+    hash) to your document by placing each member of the 
+    list on a new line, with a colon seperating the key 
+    from its value.  In YAML, this type of list is called 
+    a mapping. 
+yaml: | 
+    foo: whatever 
+    bar: stuff 
+php: | 
+    array('foo' => 'whatever', 'bar' => 'stuff')
+--- 
+test: Sequence in a Mapping 
+brief: | 
+    A value in a mapping can be a sequence. 
+yaml: | 
+    foo: whatever 
+    bar: 
+     - uno 
+     - dos 
+php: | 
+    array('foo' => 'whatever', 'bar' => array('uno', 'dos'))

+     name: steve

+    ) 
+---

+test: Mapping-in-Sequence Shortcut 
+todo: true
+brief: | 
+     If you are adding a mapping to a sequence, you 
+     can place the mapping on the same line as the 
+     dash as a shortcut. 
+yaml: | 
+     - work on YAML.py: 
+        - work on Store 
+php: | 
+    array(array('work on YAML.py' => array('work on Store')))
+---
+test: Sequence-in-Mapping Shortcut
+todo: true
+brief: |
+     The dash in a sequence counts as indentation, so
+     you can add a sequence inside of a mapping without
+     needing spaces as indentation.
+yaml: |
+     allow:
+     - 'localhost'

+test: Merge key
+brief: |
+     A merge key ('<<') can be used in a mapping to insert other mappings.  If
+     the value associated with the merge key is a mapping, each of its key/value
+     pairs is inserted into the current mapping.
