compat.etl.lua

-- Form B inline descriptor for the Embedded Template Library (ETL), a
-- header-only collection of fixed-capacity containers and utilities for
-- resource-constrained systems.
--
-- The upstream CMake target is INTERFACE-only and exposes `include/`, so a
-- small C anchor gives mcpp a buildable library target while consumers use
-- headers such as `<etl/vector.h>`.
--
-- ETL supports older language modes, but this package is built by mcpp, whose
-- supported C++ standard starts at C++20. The package therefore uses C++23
-- for its anchor and remains compatible with C++20 consumers.
