-/// @section main_intro Introduction
-/// Welcome to the clang project.
-///
-/// This documentation describes the @b internal software that makes 
-/// up clang, not the @b external use of clang. There are no instructions
-/// here on how to use clang, only the APIs that make up the software. For 
-/// usage instructions, please see the programmer's guide or reference 
-/// manual.
-///
-/// @section main_caveat Caveat 
-/// This documentation is generated directly from the source code with doxygen. 
-/// Since clang is constantly under active development, what you're about to
-/// read is out of date!
