 | /// \section main_intro Introduction | 
 | /// Welcome to LLVM. | 
 | /// | 
 | /// This documentation describes the **internal** software that makes | 
 | /// up LLVM, not the **external** use of  LLVM. There are no instructions | 
 | /// here on how to use LLVM, 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 LLVM is constantly under active development, what you're about to | 
 | /// read is out of date! However, it may still be useful since certain portions | 
 | /// of LLVM are very stable. |
