  ---------------------------------------------------------------------

  This program finds the best combination of one, two or three resistors
  with a tolerance of 1% from the E6 series to match a specified resistance.

  The resistance is specified in Ohm. The SI-prefixes 'k' and 'M' are
  supported. The unit string 'Ohm' is optional. All whitespaces in the
  input are ignored and the input is case-insensitive.
