+ (description
+ "The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're
+not widely-known, sometimes misused, and so programs that use Bigstrings are
+slower than they have to be. And even if a library got that part right and
+exposed the intrinsics properly, the compiler doesn't have any fast blits
+between Bigstrings and other string-like types. @code{bigstringaf} provides
+these missing pieces.")
