+# A simple 'tee' implementation, using perl tie.
+#
+# Whenever you print to the handle, it gets forwarded to a list of
+# handles. The list of output filehandles is passed to the constructor.
+#
+# This is similar to IO::Tee, but only used for output. Only the PRINT
+# method is currently implemented; that's all we need. We don't want to
+# depend on IO::Tee just for this.
