+     "This package provides an implementation of JSON in ANSI C as specified
+in RFC 8259.
+Features:
+@itemize
+@item Fast: can read or write gigabytes per second JSON data on modern CPUs.
+@item Portable: complies with ANSI C (C89) for cross-platform compatibility.
+@item Strict: complies with
+@url{https://datatracker.ietf.org/doc/html/rfc8259,RFC 8259} JSON standard,
+ensuring strict number format and UTF-8 validation.
+@item Extendable: offers options to allow comments, trailing commas, NaN/Inf,
+ and custom memory allocator.
+@item Accuracy: can accurately read and write @code{int64}, @code{uint64}, and
+@code{double} numbers.
+@item Flexible: supports unlimited JSON nesting levels, @code{\\u0000}
+characters, and non null-terminated strings.
+@item Manipulation: supports querying and modifying using JSON Pointer,
+JSON Patch and JSON Merge Patch.
+@item Developer-Friendly: easy integration with only one @code{.h} and one
+@code{.c} file.
