-	 * Configures the nodes in this network so that they can run in a private
-	 * network and don't require public directory servers or onion routers from
-	 * the Internet. This configuration should be done after configuring the
-	 * nodes and before writing configurations to disk. This operation can only
-	 * be invoked, if network status is
-	 * <code>NetworkState.CONFIGURING_NODES</code>.
+	 * Configures this network as private Tor network by exchanging directory
+	 * strings and router fingerprints between the nodes of this network.
+	 * Afterwards, the nodes will be able to run a private Tor network,
+	 * separated from public directory servers and onion routers.
 	 * </p>
 	 * 
 	 * <p>
-	 * The main requirement for this method lies in the fact that all nodes need
-	 * to be configured so that they accept our own directory nodes instead of
-	 * the pre-configured directory nodes from the public Tor network. This
-	 * configuration requires the fingerprints of all directory nodes. These
-	 * fingerprints are written to disk by the directory nodes as soon as they
-	 * are started. But the directories need to be configured before being
-	 * started, too, in order to prevent them from becoming part of the public
-	 * Tor network. And now we have the chicken or the egg dilemma.
+	 * The configuration is done in two steps:
+	 * <ol>
+	 * <li>Directory strings of directory nodes are added to the configurations
+	 * of all nodes in the other network.</li>
+	 * <li>Router fingerprints of all router and directory nodes are added to
+	 * the <code>approved-routers</code> files of the directory nodes.</li>
+	 * </ol>
 	 * </p>
 	 * 
 	 * <p>
-	 * The non-trivial solution is to configure the directory nodes with a fake
-	 * directory configuration and start them using the
-	 * <code>--list-fingerprint</code> option. Hence they write a
-	 * <code>fingerprint</code> file to disk and shut down immediately. This
-	 * fingerprint can be read, and all nodes can be configured to use the
-	 * directory using this fingerprint.
+	 * This operation may be invoked in any state of the contained nodes.
+	 * However, a network that does not have directory nodes of its own but
+	 * relies on directory nodes of a merged network <b>should not be started
+	 * before being configured as private network!</b> Otherwise it would
+	 * connect to the public Tor network before being merged with the other
+	 * private Tor network. However, it may also be invoked at a later time,
+	 * e.g. to admit new nodes.
 	 * </p>
 	 * 
 	 * <p>
-	 * A second, non-trivial task is to authorize routers and directory nodes.
-	 * Therefore, an authoritative directory needs to know all fingerprints of
-	 * authorized nodes. They are stored in the <code>approved-routers</code>
-	 * file in the working directory of the directory node.
+	 * This operation does not write any configurations to disk and neither
+	 * starts a nodes nor sends HUP signals to running nodes. These operations
+	 * are left to the application, so that they have more control over the
+	 * network behavior.
 	 * </p>
 	 * 
 	 * <p>
-	 * The complete task is encapsulated in this method for convenience.
-	 * However, all operations could also be performed directly on the nodes, if
-	 * required.
+	 * Applications need to ensure that there are enough directory nodes (2) and
+	 * router nodes (3) in the network to allow normal operation.
