+# A subclass of ERB that writes directly to an IO.  Credit to Aaron Patterson
+# and Masatoshi SEKI.
+#
+# To use:
+#
+#   erbio = RDoc::ERBIO.new '<%= "hello world" %>', nil, nil
+#
+#   open 'hello.txt', 'w' do |io|
+#     erbio.result binding
+#   end
+#
+# Note that binding must enclose the io you wish to output on.
