+# 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
