tem_lua_requires_module Module

This module is used to track the requires in loaded Lua scripts.

The purpose of this functionality is it to enable the loading of all Lua scripts on a single process and broadcasting them to all others, without the need to access the files by all processes.

This script amends the require and the Lua searcher, such that they report the loaded Lua files in the track_rq table.

The filled table can then be used to fetch all required files for the given script. It therefore should be executed before the actual configuration, and evaluated after the configuration script is executed.
