+for portability and modularity.  It supports a range of object file formats,
+including Linux and *BSD a.out, ELF, COFF, Mach-O, Microsoft 16-bit OBJ,
+Windows32 and Windows64.  It will also output plain binary files.  Its syntax
+is designed to be simple and easy to understand, similar to Intel's but less
+complex.  It supports all currently known x86 architectural extensions, and
+has strong support for macros.")
