# Mirrors build_release.ps1: runs `cargo build --release`, then assembles dist/:
# the five binaries (g, gufran, cpm, apm, g-lsp), a TCC built from source in bin/,
# the runtime shims, and the standard library. End users need no Rust, no Cargo,
# and no manually installed C compiler.

# fails there and 'g --run' falls back to tcc/gcc/clang on PATH (macOS ships
# clang). Every other runner gets a fully bundled TCC.
