Lua Version Manager

This aim at solving running multiple lua in one environment

I am new to Lua, and I am having problems understanding the support of Lua 5.3 with various tools. and how runtimes can not be mixed.

I am using ArchLinux as my favorite distro, which comes with Lua 5.3 by default.

I install openresty, luarocks and then lapis and encountered some 5.1 versus 5.2 versus 5.3 incompatiblity...

Searching the web for similar problems, I found my 2-3 years old post asking for Lua 5.2 support. And also people wishing for an easy version switcher. And I could not find recent answers on that matter.

So I thought building a very simple one.

This if my first draft, feel free to open a pull request to make it better.

For now, it allow me to switch lua easily.

I am taking care of setting aliases for lua and luac And updating a symlink to the ~/.luarocks/bin

I also wrote a quick wrapper around luarocks so that the version specific bin folder exist. and the proper luarocks is being used.
