general-purpose multi-platform x86 assembler
This is a distribution of NASM, the Netwide Assembler. NASM is a prototype general-purpose x86 assembler. It will currently output flat-form binary files, a.out, COFF and ELF Unix object files, Microsoft Win32 and 16-bit DOS object files, OS/2 object files, the as86 object format, and a home-grown format called RDF. Also included is NDISASM, a prototype x86 binary-file disassembler which uses the same instruction table as NASM.
