Detailed Description

template<typename T>
class _option< T >

A variable in your program, controlled by a command line option.

An _option<T> links a variable of type T with a command line option that's identified by a name (string). The variable name (known only to the programmer and to the C++ compiler) and the option name (known only to the programmer and to the user) may coincide, but need not. Objects of type _option<T> are not usually created directly by the programmer, but rather by the Options::Add() method.

_option<T> inherits an interface from _optionbase, and provides storage for a pointer to its variable. The SetValue() and GetValue() members affect the variable that the _option<T> object refers to.
