+# = Overview
+#
+# Psych is a YAML parser and emitter.
+# Psych leverages libyaml [Home page: http://pyyaml.org/wiki/LibYAML]
+# or [HG repo: https://bitbucket.org/xi/libyaml] for its YAML parsing
+# and emitting capabilities. In addition to wrapping libyaml, Psych also
+# knows how to serialize and de-serialize most Ruby objects to and from
+# the YAML format.
+#
+# = I NEED TO PARSE OR EMIT YAML RIGHT NOW!
+#
+# # Parse some YAML
+# Psych.load("--- foo") # => "foo"
+#
+# # Emit some YAML
+# Psych.dump("foo") # => "--- foo\n...\n"
+# { :a => 'b'}.to_yaml # => "---\n:a: b\n"
+#
+# Got more time on your hands? Keep on reading!
+#
+# == YAML Parsing
+#
+# Psych provides a range of interfaces for parsing a YAML document ranging from
+# low level to high level, depending on your parsing needs. At the lowest
+# level, is an event based parser. Mid level is access to the raw YAML AST,
+# and at the highest level is the ability to unmarshal YAML to Ruby objects.
+#
+# == YAML Emitting
+#
+# Psych provides a range of interfaces ranging from low to high level for
+# producing YAML documents. Very similar to the YAML parsing interfaces, Psych
+# provides at the lowest level, an event based system, mid-level is building
+# a YAML AST, and the highest level is converting a Ruby object straight to
+# a YAML document.
+#
+# == High-level API
+#
+# === Parsing
+#
+# The high level YAML parser provided by Psych simply takes YAML as input and
+# returns a Ruby data structure. For information on using the high level parser
+# see Psych.load
+#
+# ==== Reading from a string
+#
+# Psych.load("--- a") # => 'a'
+# Psych.load("---\n - a\n - b") # => ['a', 'b']
+#
+# ==== Reading from a file
+#
+# Psych.load_file("database.yml")
+#
+# ==== Exception handling
+#
+# begin
+# # The second argument changes only the exception contents
+# Psych.parse("--- `", "file.txt")
+# rescue Psych::SyntaxError => ex
+# ex.file # => 'file.txt'
+# ex.message # => "(file.txt): found character that cannot start any token"
+# end
+#
+# === Emitting
+#
+# The high level emitter has the easiest interface. Psych simply takes a Ruby
+# data structure and converts it to a YAML document. See Psych.dump for more
+# information on dumping a Ruby data structure.
+#
+# ==== Writing to a string
+#
+# # Dump an array, get back a YAML string
+# Psych.dump(['a', 'b']) # => "---\n- a\n- b\n"
+#
+# # Dump an array to an IO object
+# Psych.dump(['a', 'b'], StringIO.new) # => #<StringIO:0x000001009d0890>
+#
+# # Dump an array with indentation set
+# Psych.dump(['a', ['b']], :indentation => 3) # => "---\n- a\n- - b\n"
+#
+# # Dump an array to an IO with indentation set
+# Psych.dump(['a', ['b']], StringIO.new, :indentation => 3)
+#
+# ==== Writing to a file
+#
+# Currently there is no direct API for dumping Ruby structure to file:
+#
+# File.open('database.yml', 'w') do |file|
+# file.write(Psych.dump(['a', 'b']))
+# end
+#
+# == Mid-level API
+#
+# === Parsing
+#
+# Psych provides access to an AST produced from parsing a YAML document. This
+# tree is built using the Psych::Parser and Psych::TreeBuilder. The AST can
+# be examined and manipulated freely. Please see Psych::parse_stream,
+# Psych::Nodes, and Psych::Nodes::Node for more information on dealing with
+# YAML syntax trees.
+#
+# ==== Reading from a string
+#
+# # Returns Psych::Nodes::Stream
+# Psych.parse_stream("---\n - a\n - b")
+#
+# # Returns Psych::Nodes::Document
+# Psych.parse("---\n - a\n - b")
+#
+# ==== Reading from a file
+#
+# # Returns Psych::Nodes::Stream
+# Psych.parse_stream(File.read('database.yml'))
+#
+# # Returns Psych::Nodes::Document
+# Psych.parse_file('database.yml')
+#
+# ==== Exception handling
+#
+# begin
+# # The second argument changes only the exception contents
+# Psych.parse("--- `", "file.txt")
+# rescue Psych::SyntaxError => ex
+# ex.file # => 'file.txt'
+# ex.message # => "(file.txt): found character that cannot start any token"
+# end
+#
+# === Emitting
+#
+# At the mid level is building an AST. This AST is exactly the same as the AST
+# used when parsing a YAML document. Users can build an AST by hand and the
+# AST knows how to emit itself as a YAML document. See Psych::Nodes,
+# Psych::Nodes::Node, and Psych::TreeBuilder for more information on building
+# a YAML AST.
+#
+# ==== Writing to a string
+#
+# # We need Psych::Nodes::Stream (not Psych::Nodes::Document)
+# stream = Psych.parse_stream("---\n - a\n - b")
+#
+# stream.to_yaml # => "---\n- a\n- b\n"
+#
+# ==== Writing to a file
+#
+# # We need Psych::Nodes::Stream (not Psych::Nodes::Document)
+# stream = Psych.parse_stream(File.read('database.yml'))
+#
+# File.open('database.yml', 'w') do |file|
+# file.write(stream.to_yaml)
+# end
+#
+# == Low-level API
+#
+# === Parsing
+#
+# The lowest level parser should be used when the YAML input is already known,
+# and the developer does not want to pay the price of building an AST or
+# automatic detection and conversion to Ruby objects. See Psych::Parser for
+# more information on using the event based parser.
+#
+# ==== Reading to Psych::Nodes::Stream structure
+#
+# parser = Psych::Parser.new(TreeBuilder.new) # => #<Psych::Parser>
+# parser = Psych.parser # it's an alias for the above
+#
+# parser.parse("---\n - a\n - b") # => #<Psych::Parser>
+# parser.handler # => #<Psych::TreeBuilder>
+# parser.handler.root # => #<Psych::Nodes::Stream>
+#
+# ==== Receiving an events stream
+#
+# parser = Psych::Parser.new(Psych::Handlers::Recorder.new)
+#
+# parser.parse("---\n - a\n - b")
+# parser.events # => [list of [event, args] lists]
+# # event is one of: Psych::Handler::EVENTS
+# # args are the arguments passed to the event
+#
+# === Emitting
+#
+# The lowest level emitter is an event based system. Events are sent to a
+# Psych::Emitter object. That object knows how to convert the events to a YAML
+# document. This interface should be used when document format is known in
+# advance or speed is a concern. See Psych::Emitter for more information.
+#
+# ==== Writing to a Ruby structure
+#
+# Psych.parser.parse("--- a") # => #<Psych::Parser>
+#
+# parser.handler.first # => #<Psych::Nodes::Stream>
+# parser.handler.first.to_ruby # => ["a"]
+#
+# parser.handler.root.first # => #<Psych::Nodes::Document>
+# parser.handler.root.first.to_ruby # => "a"
+#
+# # You can instantiate an Emitter manually
+# Psych::Visitors::ToRuby.new.accept(parser.handler.root.first)
+# # => "a"

+ #
+ # === Example

+ # Given the following YAML:

+ # = Overview
+ #
+ # When using Psych.load to deserialize a YAML document, the document is
+ # translated to an intermediary AST. That intermediary AST is then
+ # translated in to a Ruby object graph.
+ #
+ # In the opposite direction, when using Psych.dump, the Ruby object graph is
+ # translated to an intermediary AST which is then converted to a YAML
+ # document.
+ #
+ # Psych::Nodes contains all of the classes that make up the nodes of a YAML
+ # AST. You can manually build an AST and use one of the visitors (see
+ # Psych::Visitors) to convert that AST to either a YAML document or to a
+ # Ruby object graph.
+ #
+ # Here is an example of building an AST that represents a list with one
+ # scalar:
+ #
+ # # Create our nodes
+ # stream = Psych::Nodes::Stream.new
+ # doc = Psych::Nodes::Document.new
+ # seq = Psych::Nodes::Sequence.new
+ # scalar = Psych::Nodes::Scalar.new('foo')
+ #
+ # # Build up our tree
+ # stream.children << doc
+ # doc.children << seq
+ # seq.children << scalar
+ #
+ # The stream is the root of the tree. We can then convert the tree to YAML:
+ #
+ # stream.to_yaml => "---\n- foo\n"
+ #
+ # Or convert it to Ruby:
+ #
+ # stream.to_ruby => [["foo"]]
+ #
+ # == YAML AST Requirements
+ #
+ # A valid YAML AST *must* have one Psych::Nodes::Stream at the root. A
+ # Psych::Nodes::Stream node must have 1 or more Psych::Nodes::Document nodes
+ # as children.
+ #
+ # Psych::Nodes::Document nodes must have one and *only* one child. That child
+ # may be one of:
+ #
+ # * Psych::Nodes::Sequence
+ # * Psych::Nodes::Mapping
+ # * Psych::Nodes::Scalar
+ #
+ # Psych::Nodes::Sequence and Psych::Nodes::Mapping nodes may have many
+ # children, but Psych::Nodes::Mapping nodes should have an even number of
+ # children.
+ #
+ # All of these are valid children for Psych::Nodes::Sequence and
+ # Psych::Nodes::Mapping nodes:
+ #
+ # * Psych::Nodes::Sequence
+ # * Psych::Nodes::Mapping
+ # * Psych::Nodes::Scalar
+ # * Psych::Nodes::Alias
+ #
+ # Psych::Nodes::Scalar and Psych::Nodes::Alias are both terminal nodes and
+ # should not have any children.
