+This directory contains various "experiment" programs used to determine
+the behavior of the java.net class where such behavior is not sufficiently
+documented by Sun in order to write an implementation from docs alone.
+
+Some key findings:
+
+The setOption/getOption methods are discussed in the "Networking Enhancements"
+document for Java 1.1 but are not in the javadocs. However, the SocketImpl
+class is shown implementing a SocketOptions interface that is not documented.
+We assume this is a non-public interface which contains abstract declarations
+of the get/setOption methods as well as contants for the option_id's.
+
+TCP_NODELAY:
+ The option id of this option is 1. The Object passed to setOption is
+ a Boolean indicating whether this option should be on (true) or off (false).
+
+SO_LINGER:
+ The option id of this option is 128. When SO_LINGER is to be disabled,
+ the Object passed to setOption is Boolean with a value of false. When
+ SO_LINGER is to be enabled, the Object passed to setOption is an Integer
+ set to the linger value.
+
+SO_TIMEOUT:
+ The option id of this option is 4102. The Object passed to setOption is
+ an Integer that is the new timeout value (0 to disable).
+
+
