Unofficial temporary fork of the Factorio Standard Library, which was a project to bring Factorio modders high-quality, commonly-required utilities and tools. Compatibility with older mods which relied on the original stdlib mod is not guaranteed. This fork will likely eventually be folded into one of the other stdlib forks on the mod portal, if and when all mods that rely on it can be safely switched over.
Lua libraries for use by other mods and submods that are parts of a larger mod.
