Not so long ago I encountered a sandbox where require() was disabled. Here is my attempt at making a file merger that does just that, but without relying on the sandbox.
This tool is fully command-line and I do not intend to write a GUI for it.
luam [args] <input> [<output>] [<input2> <output2>]...
More detailed usage available with -h, examples are available with -u.
Use make.bat to build it with g++ (needs to be in PATH).
Uses the C++11 standard with standard C++ libraries.
