wren/builtin/README.md

The Wren scripts in this directory get converted to C string literals into files with a .wren.inc extension. Those are then #included into their respective .c files so that the interpreter can load them directly without having to do any file IO.

The script that does this translation is util/wren_to_c_string.py.

When any of the ".wren" files in here are changed, the Makefile automatically updates the generated C headers.
