+//! # Environment Variables
+//!
+//! This build script can make use of several environment variables to help it
+//! find the required static or shared libraries.
+//!
+//! * `LLVM_CONFIG_PATH` - provides a path to an `llvm-config` executable
+//! * `LIBCLANG_PATH` - provides a path to a directory containing a `libclang`
+//! shared library or a path to a specific `libclang` shared library
+//! * `LIBCLANG_STATIC_PATH` - provides a path to a directory containing LLVM
+//! and Clang static libraries
