   4 % The fraction field of its argument, an integral domain. The name
   5 % "Frac" was chosen here instead of "Quot" because the latter
   6 % corresponds to the term "quotient field," which can be mistaken in
   7 % some cases for... a quotient field (something mod something).

  10 % The polynomial ring whose underlying commutative ring of
  11 % coefficients is the first argument and whose indeterminates (a
  12 % comma-separated list) are the second argumnt.
