Please keep categories (## level) listed alphabetically and matching their respective folder names. Use two empty lines to separate categories for readability.

bullet

• Upstream: https://github.com/bulletphysics/bullet3
• Version: 2.89 (830f0a9565b1829a07e21e2f16be2aa9966bd28c, 2019)
• License: zlib

Files extracted from upstream source:

• src/* apart from CMakeLists.txt and premake4.lua files
• LICENSE.txt

certs

• Upstream: Mozilla, via https://apps.fedoraproject.org/packages/ca-certificates
• Version: 2018.2.26 (2018)
• License: MPL 2.0

File extracted from a recent Fedora install: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem (It can't be extracted directly from the package, as it's generated on the user's system.)

cvtt

• Upstream: https://github.com/elasota/cvtt
• Version: 1.0.0-beta4 (cc8472a04ba110fe999c686d07af40f7839051fd, 2018)
• License: MIT

Files extracted from upstream source:

• all .cpp, .h, and .txt files in ConvectionKernels/

enet

• Upstream: http://enet.bespin.org
• Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
• 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's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.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 its functionality to IPv4 only.
