-/**
- * Quick and dirty socket listener to control an I2PTunnel.  
- * Basically run this class as TunnelManager [listenHost] [listenPort] and 
- * then send it commands on that port.  Commands are one shot deals -
- * Send a command + newline, get a response plus newline, then get disconnected.
- * <p />
- * <b>Implemented commands:</b>
- * <pre>
- * -------------------------------------------------
- * lookup &lt;name&gt;\n
- * --
- * &lt;base64 of the destination&gt;\n
- *  or
- * &lt;error message, usually 'Unknown host'&gt;\n
- * 
- *  Lookup the public key of a named destination (i.e. listed in hosts.txt)
- * -------------------------------------------------
- * genkey\n
- * --
- * &lt;base64 of the destination&gt;\t&lt;base64 of private data&gt;\n
- * 
- *  Generates a new public and private key pair
- * -------------------------------------------------
- * convertprivate &lt;base64 of privkey&gt;
- * --
- * &lt;base64 of destination&gt;\n
- *  or
- * &lt;error message&gt;\n
- *
- *  Returns the destination (pubkey) of a given private key. 
- * -------------------------------------------------
- * listen_on &lt;ip&gt;\n
- * --
- * ok\n
- *  or
- * error\n
- * 
- *  Sets the ip address clients will listen on. By default this is the
- *  localhost (127.0.0.1)
- * -------------------------------------------------
- * openclient &lt;listenPort&gt; &lt;peer&gt;\n
- * --
- * ok [&lt;jobId&gt;]\n
- *  or
- * ok &lt;listenPort&gt; [&lt;jobId&gt;]\n
- *  or
- * error\n
- * 
- *  Open a tunnel on the given &lt;listenport&gt; to the destination specified
- *  by &lt;peer&gt;. If &lt;listenPort&gt; is 0 a free port is picked and returned in
- *  the reply message. Otherwise the short reply message is used.
- *  Peer can be the base64 of the destination, a file with the public key
- *  specified as 'file:&lt;filename&gt;' or the name of a destination listed in
- *  hosts.txt. The &lt;jobId&gt; returned together with "ok" and &lt;listenport&gt; can
- *  later be used as argument for the "close" command.
- * -------------------------------------------------
- * openhttpclient &lt;listenPort&gt; [&lt;proxy&gt;]\n
- * --
- * ok [&lt;jobId&gt;]\n
- *  or
- * ok &lt;listenPort&gt; [&lt;jobId&gt;]\n
- *  or
- * error\n
- * 
- *  Open an HTTP proxy through the I2P on the given
- *  &lt;listenport&gt;. &lt;proxy&gt; (optional) specifies a
- *  destination to be used as an outbound proxy, to access normal WWW
- *  sites out of the .i2p domain. If &lt;listenPort&gt; is 0 a free
- *  port is picked and returned in the reply message. Otherwise the
- *  short reply message is used.  &lt;proxy&gt; can be the base64 of the
- *  destination, a file with the public key specified as
- *  'file:&lt;filename&gt;' or the name of a destination listed in
- *  hosts.txt. The &lt;jobId&gt; returned together with "ok" and
- *  &lt;listenport&gt; can later be used as argument for the "close"
- *  command.
- * -------------------------------------------------
- * opensockstunnel &lt;listenPort&gt;\n
- * --
- * ok [&lt;jobId&gt;]\n
- *  or
- * ok &lt;listenPort&gt; [&lt;jobId&gt;]\n
- *  or
- * error\n
- * 
- *  Open an SOCKS tunnel through the I2P on the given
- *  &lt;listenport&gt;. If &lt;listenPort&gt; is 0 a free port is
- *  picked and returned in the reply message. Otherwise the short
- *  reply message is used.  The &lt;jobId&gt; returned together with
- *  "ok" and &lt;listenport&gt; can later be used as argument for the
- *  "close" command.
- * -------------------------------------------------
- * openserver &lt;serverHost&gt; &lt;serverPort&gt; &lt;serverKeys&gt;\n
- * --
- * ok [&lt;jobId&gt;]\n
- *  or
- * error\n
- * 
- *  Starts receiving traffic for the destination specified by &lt;serverKeys&gt;
- *  and forwards it to the &lt;serverPort&gt; of &lt;serverHost&gt;.
- *  &lt;serverKeys&gt; is the base 64 encoded private key set of the local
- *  destination. The &lt;joId&gt; returned together with "ok" can later be used
- *  as argument for the "close" command.
- * -------------------------------------------------
- * close [forced] &lt;jobId&gt;\n
- *  or
- * close [forced] all\n
- * --
- * ok\n
- *  or
- * error\n
- * 
- *  Closes the job specified by &lt;jobId&gt; or all jobs. Use the list command
- *  for a list of running jobs.
- *  Normally a connection job is not closed when it still has an active
- *  connection. Use the optional 'forced' keyword to close connections

+    <h2>Intro</h2>
+
+    Quartermaster, or Q for short, is a distributed file storage framework for I2P.
+
+    <h2>Features</h2>
+
+    <ul>
+      <li>Now features 'QSites' - the Q equivalent of Freenet freesites,
+        static websites which are retrievable even if author is offline</li>
+      <li>Easy web interface - interact with Q (and view/insert QSites)
+        from your web browser</li>
+      <li>Maximum expectations of content retrievability</li>
+      <li>Content security akin to Freenet CHK and SSK keys</li>
+      <li>Powerful, flexible search engine</li>
+      <li>Comfortably accommodates both permanent and transient
+        nodes without significant network disruption (for instance,
+        no flooding of the I2P network with futile
+        calls to offline nodes)</li>
+      <li>Rapid query resolution, due to distributed catalogue
+        mirroring which eliminates all in-network query traffic</li>
+      <li>Modular, extensible architecture</li>
+      <li>Simple interfaces for 3rd-party app developers</li>
+      <li>Is custom-designed and built around I2P, so no duplication of
+        I2P's encryption/anonymity features</li>
+      <li>Simple XML-RPC interface for all inter-node communication, makes it easy to
+        implement user-level clients in any language; also allows alternative
+        implementations of core server and/or client nodes.</li>
+    </ul>
+
+    <hr>
+
+    <h2>Status</h2>
+    
+    Q is presently under development, and a test release is expected soon.
+
+    <hr>
+
+    <h2>Architecture</h2>
+
+    Refer to the <a href="spec/index.html">Protocol Specification</a> for more information.

+
+    <blockquote>
+      OK, we assume here that you've already cracked the tarball, and are looking at
+      the distribution files.<br>
+      <br>
+      In order to get Q set up and running, you'll need:
+      <ol>
+        <li>An I2P router installed, set up and (permanently or transiently) running</li>
+        <li>Your system shell set up with at the environment variables:
+          <ul>
+            <li><b>CLASSPATH</b> - this should include:
+              <ul>
+                <li>The regular I2P jar files and 3rd party support jar files (eg <b>i2p.jar</b>,
+                  <b>i2ptunnel.jar</b>, <b>streaming.jar</b>,
+                  <b>mstreaming.jar</b>, <b>jbigi.jar</b>)</li>
+                <li>Apache's XML-RPC support jarfile - included in this Q distro as
+                  <b>xmlrpc.jar</b></li>
+                <li>Aum's jarfile <b>aum.jar</b>, which includes Q and all needed support code</li>
+              </ul>
+            </li>
+            <li><b>PATH</b> - your execution search path <b><i>must</i></b> include the directory
+              in which your main java VM execution program (<b>java</b>, or on windows systems,
+              <b>java.exe</b>) resides.<br>
+              <b>NOTE</b> - if <b>java[.exe]</b> is not on your <b>PATH</b>, then Q <i>will
+                not run</i>.</li>
+          </ul>
+      </ol>

+    <h2>3. Q Server or Q Client?</h2>
+
+    <blockquote>
+      Nearly everyone will want to run a <b>Q Client Node</b>.<br>
+      <Br>
+      It is only client nodes which provide users with full access to the Q network.<br>
+      <br>
+      However, if you have a (near-) permanently running I2P Router, and you're a kind and
+      generous soul, you might <i>also</i> be willing to run a <b>Q Server Node</b> in addition
+      to your <b>Q Client Node</b>.<br>
+      <br>
+      If you do choose to run a server node, you'll be expected to keep it running as near as
+      possible to 24/7. While transience of client nodes - frequent entering and leaving the
+      Q network - causes little or no disruption, transience of server nodes can significantly
+      impair Q's usability for everyone, particularly if this transience occurs frequently amongst
+      more than the smallest percentage of the server node pool.<br>
+      <br>
+      Until you're feeling well "settled in" with Q, your best approach is to just run a
+      client node for now, and add a server node later when you feel ready.<br>

+
+    <h3>4.1. Introduction</h3>
+
+    <blockquote>
+      This chapter discusses the deployment and usage of a Q Client Node, and will take you

+      <ol>
+        <li>Double-checking that you've met the installation requirements</li>
+        <li>Launching a Q Client Node</li>
+        <li>Verifying that your Q Client Node is running</li>
+        <li>If your node fails to launch, figuring out why</li>

+    <h3>4.2. Verify Your Q Installation Is Correct</h3>
+
+    <blockquote>
+      Ensure that all the needed I2P jarfiles, as well as <b>xmlrpc.jar</b> and
+      Q's very own <b>aum.jar</b> are correctly listed in your <b>CLASSPATH</b> environment
+      varaible, and your main java launcher is correctly listed in your <b>PATH</b> environment
+      variable.<br>
+      <br>
+      Typically, you will likely copy the jarfiles <b>aum.jar</b> and <b>xmlrpc.jar</b>
+      into the <b>lib/</b> subdirectory of your I2P router installation, along with all
+      the other I2P jar files. Wherever you choose to put these files, make sure they're
+      correctly listed in your <b>CLASSPATH</b>.
+      <br>
+      Also, you'll want to add execute permission to your <b>qmgr</b> (or <b>qmgr.bat</b>)
+      wrapper script, and copy it into one of the directories listed in your <b>PATH</b>
+      environment variable.<br>
+    </blockquote>
+
+    <hr>
+
+    <h3>4.3. Get Familiar With qmgr</h3>
+
+    <blockquote>
+      <b>qmgr</b> (or <b>qmgr.bat</b>) is a convenience wrapper script to save your
+      sore fingers from needless typing. It's just a wrapper which passes arguments
+      to the java command <b><code>java&nbsp;net.i2p.aum.q.QMgr</code></b><br>
+      <br>
+      You can verify you've set up qmgr correctly with the command:
+      <blockquote><code><pre>
+qmgr help</pre></code></blockquote>
+      This displays a brief summary of qmgr commands. On the other hand, the command:
+      <blockquote><code><pre>
+qmgr help verbose</pre></code></blockquote>
+      floods your terminal window with a detailed explanation of all the qmgr commands
+      and their arguments.<br>

+
+    <h3>4.4. Running A Q Client Node For The First Time</h3>
+
+    <blockquote>
+      Provided you've successfully completed the preliminaries, you can launch your
+      Q Client Node with the command:
+      <blockquote><code><pre>
+qmgr start</pre></code></blockquote>
+
+      All going well, you should have a Q Client Node now running in background.
+    </blockquote>
+
+    <hr>
+
+    <h3>4.5. Verify that your Q Client Node is actually Running</h3>
+
+    <blockquote>
+      After typed the <b>qmgr start</b> command, you will see little or no
+      evidence that Q is actually running.<br>
+      <br>
+      You can test if the node is actually up by typing the command:
+      <blockquote><code><pre>
+qmgr status</pre></code></blockquote>
+      If your Q Client Node is running, this <b>status</b> command should produce
+      something like:
+      <blockquote><code><pre>
+Pinging node at '/home/myusername/.quartermaster_client'...
+Node Ping:
+  status=ok
+  numPeers=0

+  numRemoteItems=2173</pre></code></blockquote>
+
+      If you see something like this, then smile, because Q is now up on your system.<br>
+      <br>
+      If the node launch failed, you might see something like:
+      <blockquote><code><pre>
+Pinging node at '/home/myusername/.quartermaster_client'...
+java.io.IOException: Connection refused

+        at net.i2p.aum.q.QMgr.main(QMgr.java:869)
+Failed to ping node</pre></code></blockquote>
+      This indicates that your Q client node has either crashed, or failed to launch in the
+      first place.<br>
+      <br>
+      If you're having trouble like this, you might like to try running your Q client node
+      in foreground, instead of spawning it off into background.<br>
+      <br>
+      The command to run a Q client node in foreground is:
+      <blockquote><code><pre>
+qmgr foreground</pre></code></blockquote>
+      You should see some meaningless startup messages, and no return to your shell prompt.<br>
+
+    </blockquote>
+
+    <hr>
+
+    <h3>4.6. Diversion - Q Storage Directories</h3>
+
+    <blockquote>
+      By default, when you run a Q Client Node, it creates a datastore directory tree
+      at <b>~/.quartermaster_client</b>. (Windows users note - you'll find this directory
+      wherever your user home directory is - this depends on what version of Windows
+      you have installed).<br>
+      <br>
+      Within this directory tree, you should see a file called <b>node.log</b>, which
+      will contain various debug log messages, and can help you to rectify any problems
+      with your Q installation. If you hit a wall and can't rectify the problems
+      yourself, you should send this file to the Q author (aum).<br>
+      <br>
+      It's possible to run your Q node from another directory, by passing that directory
+      as a <b>-dir &lt;path&gt;</b> argument to the
+      <b>qmgr</b> <b>start</b>, <b>foreground</b> and <b>stop</b>
+      commands. See <b>qmgr help verbose</b> for more information.

+
+    <hr>
+
+    <h3>4.7. Importing a Noderef</h3>
+
+    <blockquote>
+      Note from the prior <b>qmgr status</b> command the line:
+      <blockquote><code><pre>
+numPeers=0</pre></code></blockquote>
+      This means that your Q client node is running standalone, and doesn't have any contact
+      with any Q network. As such, your node is effectively useless. We need to hook up
+      your node with other nodes in the Q network.<br>
+      <br>
+      Q doesn't ship with any means for new client nodes to automatically connect to any Q
+      server nodes. This is deliberate.<br>
+      <br>
+      In all likelihood, there will be one 'main' Q network running within I2P, largely
+      based around the author's own Q server node, and most people will likely want to
+      use this Q network. But the author doesn't want to stop other people running their
+      own private Q networks, for whatever purpose has meaning for them.
+
+      <blockquote><i><small>
+        <hr>
+        This is especially relevant for Q as opposed to Freenet. With Freenet, there's
+        no way for a user to know of the existence of any item of content without
+        first being given its 'key'. However, since Q works with published catalogs,
+        any user can know everything that's available on a Q network, which might
+        not be desirable to those wishing to share content in a private situation.<br>
+        <Br>
+        The Q author anticipates, and warmly supports, people running their own
+        private Q networks within I2P, in addition to accessing the mainstream
+        'official' Q network.<br>
+        <br>
+        The way Q is designed and implemented, there is no way for anyone, including
+        Q's author, to know of the existence of anyone else's private Q network.
+        It is beyond the author's control, (and thus arguably the author's
+        legal responsibility), what private Q networks people set up, and what
+        kind of content is trafficked on these networks. This claim of plausible
+        deniability on the part of Q's author parallels that of a hardware retailer
+        denying responsibility for what people do with tools that they purchase.

+
+      Ok, getting back on topic - your brand new virgin Q client node is useless and lonely,
+      and desperately needs some Q server nodes to talk to. So let's hook up your node to
+      the mainstream Q network.<br>
+      <br>
+      You'll need to get one or more 'noderefs' for Q server nodes.<br>
+      <br>
+      There's nothing fancy about a Q noderef. It's just a regular I2P 'destination', with
+      which your Q Client Node can connect with a Q Server Node.<br>
+      <br>
+      A 'semi-official' list of noderefs for the mainstream Q network can be downloaded
+      from the url: <a href="http://aum.i2p/q/qnoderefs.txt">http://aum.i2p/q/qnoderefs.txt</a>.<br>
+      <br>
+      Download this file, save it as (say) <b>qnoderefs.txt</b>. (Alternatively, if you're
+      wanting to subscribe into a private Q network, then get a noderef for at least one
+      of that network's server nodes from someone on that network who trusts you).<br>
+      <br>
+      Import these noderefs into your Q client node via the command:
+      <blockquote><code><pre>
+qmgr addref qnoderefs.txt</pre></code></blockquote>
+      If all goes well, you should see no output from this command, or (possibly) a brief
+      line or two suggesting success.<br>
+      <br>
+      Your client node is now subscribed into the Q network of your choice. Verify this
+      with the command:
+      <blockquote><code><pre>
+qmgr status</pre></code></blockquote>
+      In the output from that command, you should see the <b>numPeers=</b> line showing at least
+      1 peer.<br>
+      <br>
+      If there is more than one Q Server Node on the Q network you've just subscribed to,
+      then your local node should sooner or later discover all these server nodes, and
+      the <b>numPeers</b> value should increase over time.<br>
+      <br>
+      <blockquote>
+        <hr>
+        While Q is in its early development and testing stages, the author may abdicate
+        the mainstream Q network, and publish nodrefs for a whole new mainstream Q network.
+        This will especially happen if the author makes any substantial changes to the
+        inter-node protocol, and/or releases incompatible new versions of Q client/server
+        nodes. Remember that
+        <a href="http://aum.i2p/q/qnoderefs.txt">http://aum.i2p/q/qnoderefs.txt</a> will
+        serve as the authoritative source for noderefs for the mainstream Q network within
+        the mainstream I2P network.
+        <hr>
+      </blockquote>
+
+      When your client node gets its noderefs to a Q network, it will periodically,
+      from then on, retrieve differential peer list and catalog updates from servers
+      it knows about.<br>
+      <br>
+      Even if you only feed your client just one ref for a single server node, it will
+      in time discover all other operating server nodes on that Q network, and will
+      build up a full local catalog of everything that's available on that Q network.<br>
+      <br>
+      Provided that your client is running ok, and has been fed with at least one
+      ref for a live Q network that contains content, then over time, successive:
+      <blockquote><code><pre>
+qmgr status</pre></code></blockquote>
+      commands should report increasing values in the fields:
+      <ul>
+        <li><b>numPeers</b> - number of peers this client node knows about</li>
+        <li><b>numLocalItems</b> - number of locally stored content items, ie items
+          which you have either inserted to, or retrieved from, your client node</li>
+        <li><b>numRemoteItems</b> - number of unique data items which are available
+          on remote server nodes in the Q network, and which can be retrieved through
+          your local client node.</li>
+      </ul>
+
+      <blockquote>
+        <hr>
+
+        <h4>4.7.1. One Big Warning</h4>
+
+        If you are participating in more than one distinct Q network, then <b>do not</b>
+        insert noderefs for different networks into the same running instance of a
+        local Q client, unless you don't plan on inserting content via that client.<br>
+        <Br>
+        For instance, let's say you are participating in two different Q networks:
+        <ul>
+          <li>The 'mainstream' Q netowrk</li>
+          <li>A secret Q network - "My friends' teen angst diaries"</li>
+        </ul>
+        If you get a noderef for both these networks, and insert both of these into the
+        same running Q client node, then this local client node will be transparently
+        connected to both networks.<br>
+        <br>
+        If you only ever plan on retrieving content, and never inserting content, this
+        won't be a problem, except that you won't be able to tell which content
+        resides on the mainstream Q network, and which resides in the secret Q network.<br>
+        <Br>
+        The big problem arises from inserting content. Whenever you insert data through this
+        'contaminated' 
+        Q client node, this node picks 3 different servers to which upload a copy of this
+        data. You won't have any control over whether the data gets inserted to the mainstream
+        Q network, or your secret Q network. You might insert something sensitive, intending it
+        to go only into the secret Q network, where in fact it also ends up in the mainstream
+        network, with consequences you might not want.

+
+    <h3>4.8. Content Data and Metadata</h3>
+
+    <blockquote>
+      Whenever content gets stored on Q, it is actually stored as two separate items:
+      <ul>
+        <li>The <b>raw data</b> - whether a text file, or the raw bytes of image files,
+          audio files etc</li>
+        <li>The <b>metadata</b>, which contains human-readable and machine-readable
+          descriptions of the data</li>
+      </ul>
+      Metadata consists of a set of <b>category=value</b> pairs.<br>
+      <br>
+      Confused yet? Don't worry, I'm confused as well. Let's illustrate this with an
+      example of metadata for an MP3 audio recording:
+      <ul>
+        <li>title=Fight_Last_Thursday.mp3</li>
+        <li>type=audio</li>
+        <li>mimetype=audio/mpeg</li>
+        <li>abstract=upcoming single recorded in our garage last April</li>
+        <li>keywords=grunge,country,indie</li>
+        <li>artist=Ring of Fire</li>
+        <li>size=4379443</li>
+        <li>contact=ring-of-fire@mail.i2p</li>
+        <li>key=blah37blah24-yada23hfhyada</li>
+      </ul>
+      All metadata categories are optional. In fact, you can insert content with no metadata
+      at all.<br>
+      <br>
+      If you fail to provide metadata when inserting an item, a blank set of metadata will
+      be created with at least the following categories:
+      <ul>
+        <li><b>key</b> - the derived key, under which the item will later be retrievable
+          by yourself and others</li>
+        <li><b>title</b> - if not provided at insert time, this will be set to the key</li>
+        <li><b>size</b> - size of the item's raw data, in bytes</li>
+      </ul>
+      Within Q, there is a convention to supply a minimal amount of metadata. While this
+      is not expected or enforced, including all these categories is most strongly
+      recommended. These core categories are:
+      <ul>
+        <li><b>title</b> - a meaningful title for the data item, consisting only of characters
+          which are legal in filenames on all platforms, and which ends with a file extension.</li>
+        <li><b>type</b> - one of a superset of eMule classifiers, such as:
+          <ul>
+            <li><b>text</b> - plain text</li>
+            <li><b>html</b> - HTML content</li>
+            <li><b>image</b> - content is in an image format, such as .png, .jpg, .gif etc</li>
+            <li><b>audio</b> - content is an audio sample, such as .ogg, .mp3, .wav etc</li>
+            <li><b>video</b> - due to the sheer size of video files, and Q's present design,
+              it's unlikely people will be inserting video content anytime soon (unless it's
+              very short)</li>
+            <li><b>archive</b> - packed file collections, such as .tar.gz, .zip, .rar etc</li>
+            <li><b>misc</b> - content does not fit into any of the above categories</li>
+          </ul>
+        </li>
+        <li><b>mimetype</b> - not as important as the <b>type</b> category, but providing
+          this category in your metadata is still strongly encouraged. Value for this category
+          should be one of the standard mimetypes, eg <b>text/html</b>, <b>audio/ogg</b> etc.</li>
+        <li><b>abstract</b> - a short description (<255 characters), intended for human reading</li>
+        <li><b>keywords</b> - a comma-separated list of keywords, intended for
+          machine-readability, should be all lowercase, no spaces</li>
+      </ul>
+      Note that you can supply extra metadata categories in addition to the above, and that
+      people searching for content can search on these extra categories if they know about
+      them.

+    <h3>4.9. Searching For Content</h3>
+
+    <blockquote>
+      As mentioned earlier - in constrast with Freenet, local Q nodes build up a complete
+      catalog of all available content on whatever Q network they are connected to.<br>
+      <br>
+      This is a design decision, based on the choice to eliminate query traffic.<br>
+      <br>
+      The author hopes that this will result in a distributed storage network with a
+      high retrievability guarantee, in contrast with freenet which offers no such
+      guarantee.<br>
+      <br>
+      With Freenet, you only ever know of the existence of something if someone tells
+      you about it.<br>
+      <br>
+      But with Q, your local client node builds up a global catalog of everything that's
+      available within the whole network.<br>
+      <br>
+      The QMgr client has a command for searching your Q client node:
+      <blockquote><code><pre>
+qmgr search -m category1=pattern1 category2=pattern2 ...</pre></code></blockquote>
+      For example:
+      <blockquote><code><pre>
+qmgr search -m type=audio artist=Mozart keywords=symphony</pre></code></blockquote>
+      or:
+      <blockquote><code><pre>
+qmgr search -m type=text title="bible|biblical|(Nag Hammadi)" keywords="apocrypha|Magdalene"</pre></code></blockquote>
+      As implied in the latter example, search patterns are regular expressions. This example will
+      locate all text items, whose <b>title</b> metadata category contains one of <b>bible</b>, <b>biblical</b> or <b>Nag&nbsp;Hammadi</b>, <i>and</i> whose <b>keywords</b> category contains either
+      or both the words <b>apocrypha</b> or <b>Magdalene</b>.<br>
+      <br>
+      Please use the search function carefully, otherwise (if and when Q usage grows) you
+      could be inundated with thousands or even millions of entries.<br>
+      <br>
+      If a search turns up nothing, qmgr will simply exit. But if it turns up one or more items,
+      it will the items out one at a time, with the key first, then each metadata entry
+      on an indented line following.
+    </blockquote>
+
+    <hr>
+
+    <h3>4.10. Retrieving Content</h3>
+
+    <blockquote>
+      Now, we're actually going to retrieve something.<br>
+      <br>
+      Presumably, after following the previous section, you will have seen one or more search
+      results come up, with the 'keys' under which the items can be accessed.<br>
+      <br>
+      Now, choose one of the keys, preferably for a short text item. Try either of the following
+      commands:
+      <blockquote><code><pre>
+qmgr get &lt;keystring&gt; something.txt</pre></code></blockquote>
+<i>or</i>:
+      <blockquote><code><pre>
+qmgr get &lt;keystring&gt; &gt; something.txt</pre></code></blockquote>
+      (both have the same effect - the first one explicitly writes to the named file, the second
+      one dumps the raw data to stdout, which we shell-redirect into the file.<br>
+      <br>
+      <b><i>Note - redirection of fetched data to a file via shell is not working at present. Use only
+          the first form till we fix the bug.</i></b>
+
+    </blockquote>
+
+    <hr>
+
+    <h3>4.11. Inserting Content</h3>
+
+    <blockquote>
+      Our last example in this walkthrough relates to inserting content.<br>
+      <br>
+      Firstly, create a small text file with 2-3 lines of text, and save it as (say)
+      myqinsert.txt.<br>
+      <br>
+      Now, think of some metadata to insert along with the file. Or, you can just use
+      the set:
+      <blockquote><code><pre>
+type=text
+keywords=test
+abstract=My simple test of inserting into Q
+title=myqinsert.txt</pre></code></blockquote>
+
+      Now, let's insert the file. Ensure your Q client node is running, then type:
+      <blockquote><code><pre>
+qmgr put myqinsert.txt -m type=text keywords=test title="myqinsert.txt" \
+ abstract="My simple test of inserting into Q"</pre></code></blockquote>
+      If all went well, this command should produce half a line of gibberish, followed
+      immediately by your shell prompt, eg:
+      <blockquote><code><pre>
+aRoFC~9MU~pM2C-uCTDBp5B7j79spFD8gUeu~BNkUf0=<b>$</b>
+</pre></code></blockquote>
+      The '$' at the end is your shell prompt, and all the characters before it are the 'key'
+      which was derived from the content you just inserted.<br>
+      <br>
+      To avoid the hassle of copying/pasting the key, you could just add output redirection
+      to the above command, eg:
+      <blockquote><code><pre>
+qmgr put myqinsert.txt -m type=text keywords=test title="myqinsert.txt" \
+ abstract="My simple test of inserting into Q" \
+ > myqinsert.key</pre></code></blockquote>
+      This will cause the generated key to be written safe and sound into the file
+      <b>myqinsert.key</b>.<br>
+      <br>
+      You can verify that this insert worked by a 'get' command, as in:
+      <blockquote><code><pre>
+qmgr get `cat myqinsert.key` somefilename.ext</pre></code></blockquote>
+      (Note that this won't work on windows because the DOS shell is irredeemably brain-damaged. If
+      you're using Windows, you <b>will</b> have to cut/paste the key.
+    </blockquote>
+
+    <hr>
+
+    <h3>4.12. Shutting Down your Node</h3>
+
+    <blockquote>
+      If you've worked through to here, then congratulations! You've got your Q Client Node set up
+      and working, and ready to meet all your distributed file storage and retrieval needs.<br>
+      <br>
+      You can leave your client node running 24/7 if you want. In fact, we recommend you keep your
+      client node running as much of the time as possible, so that you get prompt catalog updates,
+      and can more quickly stay in touch with new content.<br>
+      <br>
+      However, if you need to shut down your node, the command for doing this is:
+      <blockquote><code><pre>
+qmgr stop</pre></code></blockquote>
+      This command will take a while to complete (since the node has to wait for the I2P
+      java shutdown hooks to complete before it can rest in peace). But once your node is
+      shut down, you can start it up again at any time and pick up where you left off.

+    <h2>5. Running a Q Server Node</h2>
+
+    <h3>5.1. Introduction</h3>
+    <blockquote>
+      This section describes the requirements for, and procedures involved with, running
+      a Q Server Node.<br>
+      <br>
+      We'll use a similar 'walkthrough' style to that which we used in the previous section
+      on client nodes.
+    </blockquote>
+
+    <hr>
+
+    <h3>5.2. Requirements and Choices</h3>
+    <blockquote>
+      Running a Q server is a generous thing to do, and helps substantially with making
+      Q work at its best for everyone. However, please do make sure you can meet some
+      basic requirements:
+      <ul>
+        <li>You are running a permanent (24/7) I2P Router, on a box with at least (say)
+        98% uptime.</li>
+        <li>You have a little bandwidth to spare, and don't mind the extra memory, disk and
+          CPU-usage footprint of running a fulltime Q server node</li>
+        <li>You have already been able to successfully run a Q client node.</li>
+      </ul>
+      Also, please decide whether you want your server node to contribute to the mainstream
+      Q network, or whether you want to create your own private Q network, or join someone 
+      else's private network. Your contribution will be most appreciated, though, if you
+      can run a server within the mainstream Q network.
+    </blockquote>
+    
+    <hr>
+
+    <h3>5.3. Starting Your Server Node</h3>
+
+    <blockquote>
+      Starting up a Q Server node is very similar to starting up a Q client node, except
+      that with the qmgr command line, you must put the keyword arg <b>server</b> before the
+      command word. So the command is:
+      <blockquote><code><pre>
+qmgr server start</pre></code></blockquote>
+      Similar to Q client nodes, you can check the status of a running Q server node with
+      the command:
+      <blockquote><code><pre>
+qmgr server status</pre></code></blockquote>
+      (Note that this command will take longer to complete than with client nodes, because
+      the communication passes through a multi-hop I2P tunnel, rather than just through
+      localhost TCP).<br>
+      <br>
+      If the status command succeeds, then you'll know your new Q Server Node is happily
+      running in background.
+    </blockquote>
+
+    <hr>
+    
+    <h3>5.4. Joining A Q Network</h3>
+
+    <blockquote>
+      When a Q Server node starts up for the first time, it is in a private network
+      all by itself.<br>
+      <br>
+      If you want to link your server into an existing Q network, you'll have to add a
+      noderef for at least one other server on that network. The command to do this
+      is similar to that for subscribing a client node to a network:
+      <blockquote><code><pre>
+qmgr server addref &lt;noderef-file&gt;</pre></code></blockquote>
+      where &lt;noderef-file&gt; is a file into which you've saved the noderef for
+      the network you want to join.
+      <blockquote>
+        <hr><i><small>
+        Recall from the section on client nodes that the authoritative noderefs
+        for the mainstream Q network can be downloaded from 
+        <a href="http://aum.i2p/q/qnoderefs.txt">http://aum.i2p/q/qnoderefs.txt</a>.
+        </small></i><hr>
+      </blockquote>
+      After you've added the noderef, subsequent <b>qmgr server status</b> commands
+      should show <b>numPeers</b> having a value of at least 1 (and growing, as more
+      server nodes come online in the mainstream Q network.)
+
+    </blockquote>
+
+    <hr>
+
+    <h3>5.5. Private Networks - Exporting Your Server's Noderef</h3>
+
+    <blockquote>
+      If you're planning to start your own private Q network, and want to include other
+      server operators in this network, then you'll have to export your server's noderef
+      and make it available to the others you want to invite into your network.<br>
+      <br>
+      The command to export your Q Server noderef is:
+      <blockquote><code><pre>
+qmgr server getref &lt;noderef-file&gt;</pre></code></blockquote>
+      This will extract the <i>I2P Destination</i> of your running server node, and
+      write it into &lt;noderef-file&gt;. You can then privately share this file with
+      others who you want to invite into your private network. Each recipient of
+      this file will do a <b>qmgr server addref &lt;noderef-file&gt;</b> command
+      to import your ref into their servers.<br>
+      <br>
+      Don't forget that if you're running, or participating in, a private Q network, then
+      you'll need to run a separate client for accessing this network, separate from any
+      mainstream Q network client you may already be running.<br>
+      <br>
+      To start this extra client, you'll have to choose a directory where you want this
+      client to reside, a port number you want your client to listen on locally for
+      user commands, and run the command:
+      <blockquote><code><pre>
+qmgr -dir /path/to/my/new/client -port &lt;portnum&gt; start</pre></code></blockquote>
+      You need the <b>-port &lt;portnum&gt;</b> command, because otherwise it'll fail 
+      to launch (if you already have a client node running off the mainstream Q network).<br>
+      <br>
+      This will create, and launch, a new instance of a Q client, accessing your private
+      Q network. Don't forget to import your server's noderef into this client. Also,
+      note that you'll have to use this same <b>-port &lt;portnum&gt;</b> argument when
+      doing any operation on this client instance, such as get, put, status, search.

+    <h2>6. About the qmgr Utility</h2>
+
+    qmgr (or, to people fluent in Java, <b>net.i2p.aum.q.QMgr</b>), is just one simple
+    Q client application, that happens to be bundled in with the Q distro.<br>
+    <br>
+    It is by no means the only, or even main facility for accessing the Q network. We
+    anticipate that folks will write all manner of client apps, including fancy GUI
+    apps.<br>
+    <br>
+    Anyway, qmgr does give you a rudimentary yet workable client for basic access
+    to the Q network. Until fancy apps get written, qmgr will have to do.<br>
+    <br>
+    Don't forget that qmgr has very detailed inbuilt help. Run:
+      <blockquote><code><pre>
+qmgr help</pre></code></blockquote>
+    for a quick help summary, or:
+      <blockquote><code><pre>
+qmgr help verbose</pre></code></blockquote>
+    for the 'War and Peace' treatise.<br>
+    <br>
+    <blockquote><hr>
+    One crucial concept to remember with qmgr is that client and server node instances
+    are uniquely identified by the directories at which they reside. If you are running
+    multiple server and/or client instances, you can specify an instance with the
+    <b>-dir &lt;dirpath&gt;</b> option - see the help for details.
+      <hr></blockquote>
+
+    <hr>
+
+    One last note - we strongly discourage any writing of client apps that spawn a qmgr
+    process, pass it arguments and parse its results. This is most definitely a path to
+    pain, since qmgr's shell interface is subject to radical change at any time without
+    notice.<br>
+    <br>
+    qmgr is for human usage, or at most, inclusion in init/at/cron scripts. Please respect
+    this.<br>
+    <br>
+    If you want to write higher-level clients, your best course of action is to use the
+    official client api library, which we anticipate will have versions available in
+    Java, Python, Perl and C++. If you want to write in another language, such as
+    OCaml, Scheme etc, then the existing api lib implementations should serve as an excellent
+    reference to support you in writing a native port for your own language.

+    <h2>3. URI Determination Procedures</h2>
+
+    <h3>3.1. Plain Hash URI Calculation Procedure</h3>
+
+    When items are inserted in <code>plain</code> mode, the final URI is determined from
+    a hash of the data and metadata. Security of the item is based on the mathematical difficulty
+    of creating an arbitrary data+metadata set whose hash collides with the target URI.<br>
+    <br>
+    Specifically, the recipe for calculating plain hash URIs is:
+    <ol>
+      <li>If the key <code>size</code> is missing, set this to the size of the data,
+        in bytes</li>
+      <li>If the key <code>dataHash</code> is missing, set this to the base64-encoded
+        SHA256(data)</li>
+      <li>If the key <code>title</code> is missing, set this to the value of <code>dataHash</code></li>
+      <li>From the metadata, create a set of strings, each in the form <code>key=value</code>,
+        where each line contains a metadata <code>key</code> and its <code>value</code>, and
+        is terminated by an ASCII linefeed (\n, 0x10).</li>
+      <li>Ensure that key <code>uri</code> is omitted</li>
+      <li>Sort the strings into ascending ASCII sort order</li>
+      <li>Concatenate the strings together into one big string</li>
+      <li>Calculate the SHA256 hash of this string</li>
+      <li>Encode the hash into Base64</li>
+      <li>Prepend the string <code>Q:</code> to this</li>
+    </ol>
+
+    <a name="signedhash"/>
+
+    <hr>
+
+    <h3>3.2. Signed Space URI Calculation Procedure</h3>
+
+    This is much simpler than determining plain hash URI, since the security of the URI
+    is based not on hashes of data and metadata, but on the cryptographic <code>privateKey</code>
+    given by the application.<br>
+    <br>
+    Calculation recipe for Signed Space URIs is:
+    <ol>
+      <li>Calculate the SHA256 hash of the private key's binary data (not its base64 representation)</li>
+      <li>Encode this hash into base64, dropping any trailing '=' characters</li>
+      <li>Append to this the value of metadata item <code>path</code> (recall that <code>path</code>,
+        if not empty, must begin with a '/')</li>
+      <li>Prepend the string <code>Q:</code> to this</li>
+    </ol>
+    The resulting URI then is in the form <code>Q:pubkeyHash/path.ext</code>

+                  <blockquote><code>localhost:4444</code></blockquote>
+                  (or whatever address you have configured your I2P EEProxy to listen on,
+                  if you've changed it)<br><br>
+                  </li>
+                <li>Start up the browser you have just configured, and enter the web address:

+                  </li>
+              </ol>
+            <p>Even if you do this, you still won't have a 100% guarantee of anonymity, since
+               a malicious QSite author can send code to your browser which exploits a vulnerability
+               in the browser to compromise your anonymity (eg, accessing third party cookies, executing
+               arbitrary code, accessing your local filesystem, uploading compromising information
+               about you to hostile I2P EEPsites etc). But you can relax (somewhat) in the knowledge
+               that such attacks are much more difficult, particularly if you use a decent web browser.
