Usage: FE (word list) vars {commands}
    Given a list of words, and some number of control variables, FE
    iterates the list of commands, assigning words in the world list
    to the control variables, until the word list has been exhausted.

    Examples:

      /FE (one two three four five) x y {echo $x $y}

    would output:

      one two
      three four
      five

      /ALIAS opalot FE ($2-) x y z {mode $0 $1ooo $x $y $z}

    would op people three at a time (see the help on MODE)

    FE is inteded to replace the akwardness of recursion while still
    maintaining all the flexibility of recursion.  See the FE script
    and the WORDS script for more ideas how to use FE.

    FE also supports "extended" words.  That is, words contained inside
    double quotes, allowing FE to recognize words with spaces in
    them without breaking them up into multiple words.
