+      (description
+       "Hypergeometrica is a Common Lisp library for performing high-precision
+arithmetic, with a focus on performance.  At the heart of it all are routines
+for multiplication.  Hypergeometrica aims to support:
+
+@itemize
+@item In-core multiplication using various algorithms, from schoolbook to
+floating-point FFTs.
+@item In-core multiplication for large numbers using exact convolutions via
+number-theoretic transforms, which is enabled by 64-bit modular arithmetic.
+@item Out-of-core multiplication using derivatives of the original
+Cooley–Tukey algorithm.
+@end itemize
+
+On top of multiplication, one can build checkpointed algorithms for computing
+various classical constants, like @math{\\pi}.")
