/*
 * sym_convert — standalone CLI for legacy (.lib) -> S-expression (.kicad_sym)
 * symbol-library conversion, built as a WebAssembly module.
 *
 * It drives SCH_IO_MGR::ConvertLibrary directly from main(): no GUI, no
 * renderer, no embind bindings, no JS host logic. Wired into
 * eeschema/CMakeLists.txt behind the KICAD_SYM_CONVERTER_WASM option
 * (see scripts/kicad/build-sym-convert-wasm.sh).
 *
 * Targets:
 *   - Node:     built with -sENVIRONMENT=node -sNODERAWFS=1 (the default here);
 *               run with `node sym_convert.js in.lib out.kicad_sym`.
 *   - wasmtime: a follow-up build (no pthreads, -sSTANDALONE_WASM) lets the
 *               same code run host-less under `wasmtime sym_convert.wasm ...`.
 *
 * GPL note: this is GPL KiCad code. The artifact is meant to be invoked as a
 * separate process from the closed ingester, never linked into closed code.
