+ (description
+ "This is a standalone implementation of fortify source. It provides
+compile time buffer checks. It is libc-agnostic and simply overlays the
+system headers by using the @code{#include_next} extension found in GCC. It was
+initially intended to be used on musl based Linux distributions.
+
+@itemize
+@item It is portable, works on *BSD, Linux, Solaris and possibly others.
+@item It will only trap non-conformant programs. This means that fortify
+ level 2 is treated in the same way as level 1.
+@item Avoids making function calls when undefined behaviour has already been
+ invoked. This is handled by using __builtin_trap().
+@item Support for out-of-bounds read interfaces, such as send(), write(),
+ fwrite() etc.
+@item No ABI is enforced. All of the fortify check functions are inlined
+ into the resulting binary.
+@end itemize\n")
