rsasm 0.1.0

A multi-syntax, multi-architecture assembler
Documentation
/* The example from the README: a freestanding Linux x86-64 program.
 *
 * Assemble, link and run it with:
 *
 *     rsasm -o hello.o examples/hello.s && ld -o hello hello.o && ./hello
 *
 * CI does exactly that, which is what proves the object files rsasm writes
 * are real rather than merely well-formed byte for byte.
