+
+installation: >
+  Copy spyc.php to a directory you can
+  access with your YAML-ready PHP script.
+
+  That's it!
+
+about: >
+  From www.yaml.org:
+
+  "YAML(tm) (rhymes with 'camel') is a human-friendly, cross language,
+  Unicode based data serialization language designed around the common
+  native data structures of agile programming languages. It is broadly
+  useful for programming needs ranging from configuration files to
+  Internet messaging to object persistence to data auditing. Together
+  with the Unicode standard for characters, the YAML specification provides
+  all the information necessary to understand YAML Version 1.1 and to
+  creating programs that process YAML information.
+
+  YAML(tm) is a balance of the following design goals:
+    - YAML documents are very readable by humans.
+    - YAML interacts well with scripting languages.
+    - YAML uses host languages' native data structures.
+    - YAML has a consistent information model.
+    - YAML enables stream-based processing.
+    - YAML is expressive and extensible.
+    - YAML is easy to implement."
+
+  YAML makes a lot of sense.  It's easy to use, easy to learn, and cool.
+  As the lucky stiff named why once said, "YAML is a beacon of light."
+
+  If you're new to YAML, may we suggest YAML In Five Minutes:
+    - http://yaml.kwiki.org/?YamlInFiveMinutes
+
+  If you don't have five minutes, realize that this README is a completely
+  valid YAML document.  Dig in, load this or any YAML file into an array
+  with Spyc and see how easy it is to translate friendly text into usable
+  data.
+
+  The purpose of Spyc is to provide a pure PHP alternative to Syck, a
+  simple API for loading and dumping YAML documents, a YAML loader which
+  understands a usable subset of the YAML spec, and to further spread
+  the glory of YAML to the PHP masses.
+
+  If you're at all hesitant ("usable subset of YAML?!"), navigate
+  http://yaml.org/start.html.  Spyc completely understands the YAML
+  document shown there, a document which has features way beyond the
+  scope of what normal config files might require.  Try it for yourself,
+  and then start enjoying the peace of mind YAML brings to your life.
+
+meat and a few potatoes:
+  - concept: Loading a YAML document into PHP
+    brief: >
+      $yaml will become an array of all the data in wicked.yaml
+    code: |
+
+      include('spyc.php');
+
+      $yaml = Spyc::YAMLLoad('wicked.yaml');
+
+  - concept: Loading a YAML string into PHP
+    brief: >
+      $array will look like this:
+        array('A YAML','document in a','string')
+    code: |
+
+      include('spyc.php');
+
+      $yaml  = '- A YAML\n- document in a\n- string.';
+      $array = Spyc::YAMLLoad($yaml);
+
+  - concept: Dumping a PHP array to YAML
+    brief: >
+      $yaml will become a string of a YAML document created from
+      $array.
+    code: |
+
+      include('spyc.php');
+
+      $array['name']  = 'chris';
+      $array['sport'] = 'curbing';
+
+      $yaml = Spyc::YAMLDump($array);
+
+prior art:
+  - who: [Brian Ingerson, Clark Evans, Oren Ben-Kiki]
+    why?: >
+      The YAML spec is really a piece of work, and these guys
+      did a great job on it.  A simple and elegant language like
+      YAML was a long time coming and it's refreshing to know
+      such able minded individuals took the task to heart and
+      executed it with cunning and strength.  In addition to
+      their various noteworthy contributions to YAML parsers
+      and related projects, YAML.pm's README is a treasure trove
+      of information for knowledge seekers.  Thanks, guys.
+
+  - who: why the lucky stiff
+    why?: >
+      As the author of Syck, the code used in Ruby for the language's
+      YAML class and methods, why is indirectly (directly?) responsible
+      for my first exposure to YAML (as a config file in a Ruby web-app)
+      and the countless hours I spent playing with this sheik new data
+      format afterwards.  Syck's README is a YAML file and thus the
+      inspiration for this file and, even, this very piece of software.
+
+  - who: Steve Howell
+    why?: >
+      Python's YAML implementation.  PyYAML's README file is also YAML,
+      so it too inspired the YAML format of this README file.
+
+  - who: [Rasmus Lerdorf, Zeev Suraski, Andi Gutmans, et al]
+    why?: >
+      PHP is great at what it does best.  It's also paid a lot of my bills.
+      Thanks.
+
+bugs:
+  report: >
+    Please see Spyc's Sourceforge project page for information on reporting bugs.
+  speed: >
+    This implementation was not designed for speed.  Rather, it
+    was designed for those who need a pure PHP implementation of
+    a YAML parser and who are not overly concerned with performance.
+    If you want speed, check out Syck.
+  depth: >
+    This parser is by no means a comprehensive YAML parser.  For supported
+    features and future plans, check the website.
+  unicode: >
+    YAML is supposed to be unicode, but for now we're just using ASCII.
+    PHP has crappy unicode support but who knows what the future holds.
