Bundled Darknet model-definition (.cfg) files
=============================================

The .cfg files in this directory are the model definitions for YOLOv2, YOLOv3,
and YOLOv4 (and their tiny/spp variants). They originate from the Darknet
project and are public domain:

    pjreddie/darknet  (YOLOv1/v2/v3)  https://github.com/pjreddie/darknet
    AlexeyAB/darknet  (YOLOv4)        https://github.com/AlexeyAB/darknet

Darknet is released under the "YOLO LICENSE":

    "0. Darknet is public domain.
     1. Do whatever you want with it.
     2. Stop emailing me about it!"

LibreYOLO bundles these public-domain cfgs as the single source of truth for the
Darknet-lineage architectures: the runtime graph builder
(``libreyolo/models/darknet/net.py``) and the weight converter
(``weights/convert_darknet_weights.py``) both read them, so the architecture
definition never drifts between model and converter.

Only the .cfg text format and the numerical behaviour of the Darknet layers are
reproduced. No Darknet C source is copied into LibreYOLO.
