The Capitalize flag (<) causes all the letters in the word
    directly following it to be capitalized, except for letters that
    may be preceded by an Accept (_) or Lowercase (\) flag.

    Capitalization continues until one of the following is
    encountered:

       An expandable space
       A Break flag (|)
       A Hyphenate flag (=)
       Another Capitalize flag
       A pair of Uppercase flags (^^)
       A pair of Lowercase flags (\\)
       The end of the line

    You can pair the Capitalize flag with the Uppercase flag (^<) to
    capitalize all following text up to the next case flag.
