Detailed Description

template<typename S>
class arg_router::policy::program_intro_t< S >

Represents the program introduction.

Used by help nodes to display a brief description about the program.

If using C++17 then use the template variable helper with the S_ macro; for C++20 and higher, use the constructor directly with a compile-time string literal:

constexpr auto a = ar::policy::program_intro<S_("hello")>;
constexpr auto b = ar::policy::program_intro_t{"hello"_S};
#define S_(tok)
Note
Must be greater than one character
Template Parameters
SCompile-time string
