11 % The fraction field of its argument, an integral domain. The name
12 % "Frac" was chosen here instead of "Quot" because the latter
13 % corresponds to the term "quotient field," which can be mistaken in
14 % some cases for... a quotient field (something mod something).

17 % The polynomial ring whose underlying commutative ring of
18 % coefficients is the first argument and whose indeterminates (a
19 % comma-separated list) are the second argumnt.
