Hi! I stumbled upon another project currently not mentioned on https://sites.google.com/site/marbux/home/where-lua-is-used: OSv (an operating system designed for running on virtual machines, http://osv.io/) uses Lua to define its CLI commands (translating a REST API, see https://github.com/cloudius-systems/osv/blob/master/modules/cli/commands/dmesg.lua as an example). I don't to use OSv by myself, but it look pretty cool. Regards, Matthias
