|  | /// Welcome to the flang project. | 
|  | /// | 
|  | /// This documentation describes the **internal** software that makes | 
|  | /// up flang, not the **external** use of flang. There are no instructions | 
|  | /// here on how to use flang, only the APIs that make up the software. For | 
|  | /// usage instructions, please see the [project website](https://github.com/flang-compiler/f18) | 
|  | /// for further detail. | 
|  | /// | 
|  | /// \section main_caveat Caveat | 
|  | /// This documentation is generated directly from the source code with doxygen. | 
|  | /// Since flang is constantly under active development, what you're about to | 
|  | /// read is out of date! |
