Sorry, I've written nothing other than TestStringIO.rb in
rough/ext/stringio.

Since it doesn't have #unpack:

require 'stringio'

class Dotqread
  def initialize(fn)
    @blob = StringIO.new(File.open(fn) {|f| f.read})
  end
  def wordread
    @blob.read(2).unpack("s")[0]
  end
  def longread
    @blob.read(4).unpack("L")[0]
  end
  def txtread
    Opstring.new(@blob.read(wordread))
  end
end
