+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 configuration checks that LLVM needs in order to support multiple platforms.
+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
+dnl SECTION 5: Check for libraries
+dnl SECTION 6: Check for header files
+dnl SECTION 7: Check for types and structures
+dnl SECTION 8: Check for specific functions needed
+dnl SECTION 9: Additional checks, variables, etc.
+dnl SECTION 10: Specify the output files and generate it
