-/**
- * This class contains methods to generate UUID fields. These methods have been
- * refactored out of {@link com.eaio.uuid.UUID}.
- * <p>
- * Starting with version 2, this implementation tries to obtain the MAC address
- * of the network card. Under Microsoft Windows, the <code>ifconfig</code>
- * command is used which may pop up a command window in Java Virtual Machines
- * prior to 1.4 once this class is initialized. The command window is closed
- * automatically.
- * <p>
- * The MAC address code has been tested extensively in Microsoft Windows,
- * Linux, Solaris 8, HP-UX 11, but should work in MacOS X and BSDs, too.
- * <p>
- * If you use JDK 6 or later, the code in {@link InterfaceAddress} will be used.
