+# === Create a plist
+# You can dump an object to a plist in one of two ways:
+#
+# * <tt>Plist::Emit.dump(obj)</tt>
+# * <tt>obj.to_plist</tt>
+#   * This requires that you mixin the <tt>Plist::Emit</tt> module, which is already done for +Array+ and +Hash+.
+#
+# The following Ruby classes are converted into native plist types:
+#   Array, Bignum, Date, DateTime, Fixnum, Float, Hash, Integer, String, Symbol, Time, true, false
+# * +Array+ and +Hash+ are both recursive; their elements will be converted into plist nodes inside the <array> and <dict> containers (respectively).
+# * +IO+ (and its descendants) and +StringIO+ objects are read from and their contents placed in a <data> element.
+# * User classes may implement +to_plist_node+ to dictate how they should be serialized; otherwise the object will be passed to <tt>Marshal.dump</tt> and the result placed in a <data> element.
+#
+# For detailed usage instructions, refer to USAGE[link:files/docs/USAGE.html] and the methods documented below.

+  #
+  # +IO+ and +StringIO+ objects are encoded and placed in <data> elements; other objects are <tt>Marshal.dump</tt>'ed unless they implement +to_plist_node+.
