Detailed Description

A concrete instance of a particular driver option.

The Arg class encodes just enough information to be able to derive the argument values efficiently. In addition, Arg instances have an intrusive double linked list which is used by ArgList to provide efficient iteration over all instances of a particular option.

void Arg::renderAsInput	(	const ArgList &	Args,
		ArgStringList &	Output
	)		const

Append the argument, render as an input, onto the given array as strings.

The distinction is that some options only render their values when rendered as a input (e.g., Xlinker).
