+     "The @code{xint} bundle modules are:
+
+@itemize
+
+@item @code{xinttools} utilities of independent interest such as expandable
+and non-expandable loops,
+
+@item @code{xintcore} expandable macros implementing addition, subtraction,
+multiplication, division, and powers for arbitrarily long integers,
+
+@item @code{xint} extension of @code{xintcore}, @code{xintfrac} extends the
+scope of @code{xint} to decimal numbers, to numbers using scientific notation
+and also to (exact) fractions,
+
+@item @code{xintexpr} expandable parsers of numeric expressions using the
+standard infix notations, parentheses, built-in functions, user definable
+functions and variables (and more ...), which do either exact
+evaluations (also with fractions) or floating point evaluations under a user
+chosen precision.
+
+@item @code{xintkernel} supports macros for all the bundle constituents,
+
+@code{xintbinhex} converts to and from hexadecimal and binary bases,
+
+@code{xintgcd} provides @code{gcd()} and @code{lcm()} functions to
+@code{xintexpr},
+
+@code{xintseries}, which evaluates numerically partial sums of series and
+power series with fractional coefficients,
+
+@item and @code{xintcfrac}, dedicated to the computation and display of
+continued fractions).
+
+@end itemize
+
+All computations are compatible with expansion-only context.")
