YAML = Psych # :nodoc:
# YAML Ain't Markup Language
#
# This module provides a Ruby interface for data serialization in YAML format.
#
# The YAML module is an alias of Psych, the YAML engine for Ruby.
#
# == Usage
#
# Working with YAML can be very simple, for example:
#
# require 'yaml'
# # Parse a YAML string
# YAML.load("--- foo") #=> "foo"
#
# # Emit some YAML
# YAML.dump("foo") # => "--- foo\n...\n"
# { :a => 'b'}.to_yaml # => "---\n:a: b\n"
#
# As the implementation is provided by the Psych library, detailed documentation
# can be found in that library's docs (also part of standard library).
#
# == Security
#
# Do not use YAML to load untrusted data. Doing so is unsafe and could allow
# malicious input to execute arbitrary code inside your application. Please see
# doc/security.rdoc for more information.
#
# == History
#
# Syck was the original for YAML implementation in Ruby's standard library
# developed by why the lucky stiff.
#
# You can still use Syck, if you prefer, for parsing and emitting YAML, but you
# must install the 'syck' gem now in order to use it.
#
# In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was
# completely removed with the release of Ruby 2.0.0.
#
# == More info
#
# For more advanced details on the implementation see Psych, and also check out
# http://yaml.org for spec details and other helpful information.
#
# Psych is maintained by Aaron Patterson on github: https://github.com/ruby/psych
#
# Syck can also be found on github: https://github.com/ruby/syck
