Add the following to the "build" table of the rockspec:

build = {
    install = {
        bin = {
            "myscript.lua",
        },
    },
}

It installs shell wrapper called "myscript.lua" to the directory
<luarocks_root>/bin, e.g. to /usr/local/bin or to ~/.luarocks/bin (if
--local is in use). The wrapper calls lua with the arguments needed to
run your script as a program.

The directory <luarocks_root>/bin should be added to PATH. In
up-to-date luarocks you can do it with the following command:

$ eval $(luarocks path --bin)

Then you can call your script directly:

$ myscript.lua

--
