Return values

You can use annotation tags to describe the value that is returned by an SPL or native function.
@return <description>
Describes the value that is returned by an SPL or native function.
The following example shows the SPLDOC markup and code for a simple function.
/** 
This function returns a "hello world" message.
@return the message
*/
rstring getHelloWorldMessage() {
	return "hello world";
}

The spl-make-doc command generates documentation:
