+## `see_missing.py`
+
+### Usage
+
+[Download](https://github.com/raysan5/raylib/blob/master/tools/rlparser/output/raylib_api.json) or generate a `raylib_api.json` file (via [rlparser](https://github.com/raysan5/raylib/tree/master/tools/rlparser)) and place it in the `/tools` directory.
+
+Run the script with an appropriate Python 3 executable:
+
+```shell
+$ python3 see_missing.py
+```
+
+The script will list all raylib functions it couldn't find in the `.hpp` files under `/include`, along with their parameters.
+
+It searches for `::<name>(`. Make sure to prefix downstream raylib calls with `::`.
