+# 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.
