## Detailed Description

The entire library is confined to this namespace.

## Function Documentation

const char* banner | ( |  | ) |

| Returns a character string containing the PPL banner. The banner provides information about the PPL version, the licensing, the lack of any warranty whatsoever, the C++ compiler used to build the library, where to report bugs and where to look for further information.
