+# Hack to handle syck's DefaultKey bug with psych
+#
+# Quick note! If/when psych loads in 1.9, it will redefine
+# YAML to point to Psych by removing the YAML constant.
+# Thusly, over in Gem.load_yaml, we define DefaultKey again
+# after proper yaml library has been loaded.
+#
+# All this is so that there is always a YAML::Syck::DefaultKey
+# class no matter if the full yaml library has loaded or not.
