  2. % Computer Modern Roman upper case:
  3. % These letters were originally coded by D. E. Knuth in November, 1979,
  4. % inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
  5. % Sans serif designs by Richard Southall were added in April, 1982.
  6. % The programs were revised for the new \MF\ conventions in 1985.
  7. % Art Ogawa's mod: the sans serif I will nonetheless have serifs: for cmttss fonts.
