Hugo or any go program should fit that bill since that is one of the major selling points of go

Hugo has a ton of prebuilt executables that you just have to extract and its in a single file https://github.com/gohugoio/hugo/releases

Thanks. I had looked at Hugo before, but somehow didn't see the precompiled binary as an installation option. I'll try it out.

You don't need to use their precompiled binary either. It's available in brew (OS X), some Windows package manager (don't remember the name), distro packages, etc.

Yeah, but package managers are exactly what I want to avoid here :)
