+# 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().
