+generation written in C++ language.  It can generate machine code for X86 and
+X86_64 architectures with the support for the whole instruction set from
+legacy MMX to the newest AVX-512 and AMX.  It has a type-safe API that allows
+C++ compiler to do semantic checks at compile-time even before the assembled
+code is generated or executed.  It also provides an optional register
+allocator that makes it easy to generate complex code without a significant
+development effort.")
