30   * IListServCommand is the interface that all pluggable list serv commands must implement.
31   * The lifecycle of a IListServCommand will be controlled by the {@link ICommandListservManager}
32   *
33   * <br />
34   * <br />
35   * Requests sent to the CommandListservManager take the form of:
36   * <pre>
37   * &lt;listName&gt;-&lt;commandName&gt;@domain
38   * </pre>
39   * and if the commandName matches the command's name, then the {@link #onCommand} will be invoked.
40   *
41   * <br />
42   * <br />
43   * A typical command is configured:
44   * <pre>
45   * &lt;command name="subscribe" class="Subscribe"/&gt;
46   * </pre>
47   *
48   * <br />
49   * <br />
50   * Typically, IListServCommands will format some text to reply with based off of resource files
51   * and calls to {@link org.apache.james.util.XMLResources#getString}
52   *
53   * This allows you to customize the messages sent by these commands by editing text files and not editing the javacode.
