  # Public: Converts a TTF font file to an EOT font.
  #
  # input  - the input TTF font as a String (representing a path) or IO object
  #          (responding to #read).
  # output - the output destination as a String (representing a path) or IO
  #          object where the EOT font will be written.
  #
  # Examples:
  #
  #   TTF2EOT.convert("input.ttf", "output.eot")

  #
  # Returns the output IO object.
  # Raises TTF2EOT::ConversionError if the input data is invalid.
