But having some docs seems better than none at all. In particular, this generates stubs for the following env vars: - COLORTERM - QNX_TARGET - RUST_BACKTRACE - RUSTC_BLESS - RUSTC_BOOTSTRAP - RUSTC_BREAK_ON_ICE - RUSTC_CTFE_BACKTRACE - RUSTC_FORCE_RUSTC_VERSION - RUSTC_GRAPHVIZ_FONT - RUSTC_ICE - RUSTC_LOG - RUSTC_OVERRIDE_VERSION_STRING - RUSTC_RETRY_LINKER_ON_SEGFAULT - RUSTC_TRANSLATION_NO_DEBUG_ASSERT - RUST_DEP_GRAPH_FILTER - RUST_DEP_GRAPH - RUST_FORBID_DEP_GRAPH_EDGE - RUST_MIN_STACK - RUST_TARGET_PATH - SDKROOT - TERM - UNSTABLE_RUSTDOC_TEST_LINE - UNSTABLE_RUSTDOC_TEST_PATH [rendered]()
