+# YAML::Store
+#
+require 'yaml'
+require 'pstore'
+
+# YAML::Store provides the same functionality as PStore, except it uses YAML
+# to dump objects instead of Marshal.
+#
+# == Example
+#
+#   require 'yaml/store'
+#
+#   Person = Struct.new :first_name, :last_name
+#
+#   people = [Person.new("Bob", "Smith"), Person.new("Mary", "Johnson")]
+#
+#   store = YAML::Store.new "test.store"
+#
+#   store.transaction do
+#     store["people"] = people
+#     store["greeting"] = { "hello" => "world" }
+#   end
+#
+# After running the above code, the contents of "test.store" will be:
+#
+#   ---
+#   people:
+#   - !ruby/struct:Person
+#     first_name: Bob
+#     last_name: Smith
+#   - !ruby/struct:Person
+#     first_name: Mary
+#     last_name: Johnson
+#   greeting:
+#     hello: world
+
+class YAML::Store < PStore
+
+  # :call-seq:
+  #   initialize( file_name, yaml_opts = {} )
+  #
+  # Creates a new YAML::Store object, which will store data in +file_name+.
+  # If the file does not already exist, it will be created.
+  #
+  #
+  # Options passed in through +yaml_opts+ will be used when converting the
+  # store to YAML via Hash#to_yaml().
+  def initialize file_name, yaml_opts = {}
