+/**
+ * \file builtin_functions.cpp
+ *
+ * Support for GLSL built-in functions.
+ *
+ * This file is split into several main components:
+ *
+ * 1. Availability predicates
+ *
+ *    A series of small functions that check whether the current shader
+ *    supports the version/extensions required to expose a built-in.
+ *
+ * 2. Core builtin_builder class functionality
+ *
+ * 3. Lists of built-in functions
+ *
+ *    The builtin_builder::create_builtins() function contains lists of all
+ *    built-in function signatures, where they're available, what types they
+ *    take, and so on.
+ *
+ * 4. Implementations of built-in function signatures
+ *
+ *    A series of functions which create ir_function_signatures and emit IR
+ *    via ir_builder to implement them.
+ *
+ * 5. External API
+ *
+ *    A few functions the rest of the compiler can use to interact with the
+ *    built-in function module.  For example, searching for a built-in by
+ *    name and parameters.
