Sawyer::CommandLine::ShowVersion Class Reference


Functor to print a version string.

The string supplied to the constructor is printed to standard error followed by a line feed. Although the string is intended to be a version number, it can be anything you like. Sometimes people use this action to aid debugging of the parsing.
