MCL_Villages:
============================
A fork of Rochambeau's "Settlements" mod converted for use in MineClone2.
--------------
Using the mod:
--------------
This mod adds settlements on world generation.
And, in Creative Mode; also comes with a debug tool for spawning in villages.
-------------
MCL2 Credits:
-------------
Code forked from: https://github.com/MysticTempest/settlements/tree/mcl_villages
Commit: e24b4be
================================================================================
Basic conversion of Settlements mod for compatibility with MineClone2, plus new schematics: MysticTempest
Seed-based Village Generation, multi-threading, bugfixes: kay27
=========================
