  1. % Computer Modern Italic lower case:
  2. % This lowercase italic alphabet was prepared by D. E. Knuth in December, 1979,
  3. % inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
  4. % The programs were revised for the new \MF\ conventions in 1985.
  5.  
  6. % Character codes \0141 through \0172 are generated.
