These are the .lua files from from Pedro Souza's 2014 Summer of Code project. Rui Paulo, Pedro Arthur and Wojciech A. Koszek also contributed. Obtained from: https://wiki.freebsd.org/SummerOfCode2014/LuaLoader Sponsored by: Google Summer of Code Improve the SoC lua menu code to bring it in line with forth menu functionality Submitted by: Zakary Nafziger Sponsored by: FreeBSD Foundation Use loader.setenv and loader.unsetenv instead of loader.perform Convert from include("/boot/foo.lua") to foo = require("foo"); to bring in line with latest lua module conventions. Enforce a uniform style for the new .lua files: o hard tab indenation for 8 spaces o don't have if foo then bar; else bas; end on one line MFC After: 1 month Relnotes: yes Differential Review: https://reviews.freebsd.org/D14295
