Third party libraries

b2d_convexdecomp

• Upstream: https://github.com/erincatto/Box2D (Contributions/Utilities/ConvexDecomposition)
• Version: TBD
• License: zlib

certs

• Upstream: ?

TODO.

enet

• Upstream: http://enet.bespin.org
• Version: 1.3.13
• License: MIT

Files extracted from upstream source:

• all .c files in the main directory (except unix.c win32.c)
• the include/enet/ folder as enet/ (except unix.h win32.h)
• LICENSE file

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by godot socket implementation and allow IPv6. Two files (godot.cpp and enet/godot.h) have been added to provide enet socket implementation using Godot classes. It is still possible to build against a system wide ENet but doing so will limit it's functionality to IPv4 only. Check the diff of enet.h, protocol.c, and host.c with the 1.3.13 tarball before the next update.
