file nnn
nnn: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.32, BuildID[sha1]=1be54d27687f83cf42393dd59dba2723798956de, stripped
## Optimization tips
Careful use of make variables, static compilation and [upx](https://upx.github.io/) compression can do wonders!
```
$ make CFLAGS=-march=corei7 O_NORL=1 O_NOMOUSE=1 O_NOLOC=1 O_NOBATCH=1 O_NOSSN=1 O_NOFIFO=1 O_QSORT=1 O_NOUG=1 static
$ upx nnn-static
