		Lua BitOp is a C extension module for Lua 5.1 which adds bitwise operations on numbers.
		This version is patched to be able to build against Lua 5.3+.
		Tested with Lua 5.3 and Lua 5.4.
		Patch source: https://github.com/LuaJIT/LuaJIT/issues/384
		Lua BitOp is Copyright © 2008 Mike Pall. Lua BitOp is free software, released under the MIT/X license (same license as the Lua core).
