+module FFI

+  # FFI::ManagedStruct allows custom garbage-collection of your FFI::Structs.
+  #
+  # The typical use case would be when interacting with a library
+  # that has a nontrivial memory management design, such as a linked
+  # list or a binary tree.
+  #
+  # When the {Struct} instance is garbage collected, FFI::ManagedStruct will
+  # invoke the class's release() method during object finalization.
+  #
+  # @example Example usage:
+  #  module MyLibrary
+  #    ffi_lib "libmylibrary"
+  #    attach_function :new_dlist, [], :pointer
+  #    attach_function :destroy_dlist, [:pointer], :void
+  #  end
+  #
+  #  class DoublyLinkedList < FFI::ManagedStruct
+  #    @@@
+  #    struct do |s|
+  #      s.name 'struct dlist'
+  #      s.include 'dlist.h'
+  #      s.field :head, :pointer
+  #      s.field :tail, :pointer
+  #    end

+  #
+  #  begin
+  #    ptr = DoublyLinkedList.new(MyLibrary.new_dlist)
+  #    #  do something with the list
