Sawyer::CommandLine::ShowHelp Class Reference

Description

Functor to print the Unix man page.

This functor, when applied, creates a Unix manual page from available documentation in the parser, and then invokes standard Unix commands to format the text and page it to standard output. Strange things might happen if standard input is not the terminal, since the pager will probably be expecting to read commands from standard input.
