+dnl This is the LLVM configuration script. It is processed by the autoconf
+dnl program to produce a script named configure. This script contains the

+dnl This file is composed of 10 sections per the recommended organization of
+dnl autoconf input defined in the autoconf documentation. As this file evolves,
+dnl please keep the various types of checks within their sections. The sections
+dnl are as follows:
+dnl
+dnl SECTION 1: Initialization & Setup
+dnl SECTION 2: Architecture, target, and host checks
+dnl SECTION 3: Command line arguments for the configure script.
+dnl SECTION 4: Check for programs we need and that they are the right version
