+PEAR - The PEAR Installer
+=========================
+
+What is the PEAR Installer?  What is PEAR?
+
+PEAR is the PHP Extension and Application Repository, found at
+http://pear.php.net.  The PEAR Installer is this software, which
+contains executable files and PHP code that is used to download
+and install PEAR code from pear.php.net.
+
+PEAR contains useful software libraries and applications such as
+MDB2 (database abstraction), HTML_QuickForm (HTML forms management),
+PhpDocumentor (auto-documentation generator), DB_DataObject
+(Data Access Abstraction), and many hundreds more.  Browse all
+available packages at http://pear.php.net, the list is constantly
+growing and updating to reflect improvements in the PHP language.
+
+DOCUMENTATION
+=============
+
+Documentation for PEAR can be found at http://pear.php.net/manual/.
+Installation documentation can be found in the INSTALL file included
+in this tarball.
+
+WARNING: DO NOT RUN PEAR WITHOUT INSTALLING IT - if you downloaded this
+tarball manually, you MUST install it.  Read the instructions in INSTALL
+prior to use.
+
+
+Happy PHPing, we hope PEAR will be a great tool for your development work!

+<p class="short-description">The Structures_Graph_Node class represents a Node that can be member of a  graph node set.</p>
+<p class="description"><p>A graph node can contain data. Under this API, the node contains default data,  and key index data. It behaves, thus, both as a regular data node, and as a  dictionary (or associative array) node.</p><p>Regular data is accessed via getData and setData. Key indexed data is accessed  via getMetadata and setMetadata.</p></p>

+ <span><a name="package.database.structures_graph.tutorial.intro"></a><h2 class="title">Introduction</h2><p>Structures_Graph is a package for creating and manipulating graph datastructures. A graph is a set of objects, called nodes, connected by arcs. When used as a datastructure, usually nodes contain data, and arcs represent relationships between nodes. When arcs have a direction, and can be travelled only one way, graphs are said to be directed. When arcs have no direction, and can always be travelled both ways, graphs are said to be non directed.</p>
+  <p>Structures_Graph provides an object oriented API to create and directly query a graph, as well as a set of Manipulator classes to extract information from the graph.</p></span>
+ <span><a name="package.database.structures_graph.tutorial.creation"></a><h2 class="title">Creating a Graph</h2><p>Creating a graph is done using the simple constructor:
+   <pre class="listing"><pre>
+require_once 'Structures/Graph.php';
+
+$directedGraph =&amp; new Structures_Graph(true);
+$nonDirectedGraph =&amp; new Structures_Graph(false);
+    </pre></pre>
+   and passing the constructor a flag telling it whether the graph should be directed. A directed graph will always be directed during its lifetime. It's a permanent characteristic.</p>
+  <p>To fill out the graph, we'll need to create some nodes, and then call Graph::addNode.
+   <pre class="listing"><pre>
+require_once 'Structures/Graph/Node.php';
+
+$nodeOne =&amp; new Structures_Graph_Node();
+$nodeTwo =&amp; new Structures_Graph_Node();
+$nodeThree =&amp; new Structures_Graph_Node();
+
+$directedGraph-&gt;addNode(&amp;$nodeOne);
+$directedGraph-&gt;addNode(&amp;$nodeTwo);
+$directedGraph-&gt;addNode(&amp;$nodeThree);
+    </pre></pre>
+   and then setup the arcs:
+   <pre class="listing"><pre>
+$nodeOne-&gt;connectTo($nodeTwo);

+ <span><a name="package.database.structures_graph.tutorial.nodesanddata"></a><h2 class="title">Associating Data</h2><p>Graphs are only useful as datastructures if they can hold data. Structure_Graph stores data in nodes. Each node contains a setter and a getter for its data.
+   <pre class="listing"><pre>
+$nodeOne-&gt;setData(&quot;Node One's Data is a String&quot;);
+$nodeTwo-&gt;setData(1976);
+$nodeThree-&gt;setData('Some other string');
+
+print(&quot;NodeTwo's Data is an integer: &quot; . $nodeTwo-&gt;getData());
+    </pre></pre></p>
+  <p>Structure_Graph nodes can also store metadata, alongside with the main data. Metadata differs from regular data just because it is stored under a key, making it possible to store more than one data reference per node. The metadata getter and setter need the key to perform the operation:
+   <pre class="listing"><pre>
+$nodeOne-&gt;setMetadata('example key', &quot;Node One's Sample Metadata&quot;);
+print(&quot;Metadata stored under key 'example key' in node one: &quot; . $nodeOne-&gt;getMetadata('example key'));
+$nodeOne-&gt;unsetMetadata('example key');
+    </pre></pre></p></span>
+ <span><a name="package.database.structures_graph.tutorial.querying"></a><h2 class="title">Querying a Graph</h2><p>Structures_Graph provides for basic querying of the graph:
+   <pre class="listing"><pre>
+// Nodes are able to calculate their indegree and outdegree
+print(&quot;NodeOne's inDegree: &quot; . $nodeOne-&gt;inDegree());
+print(&quot;NodeOne's outDegree: &quot; . $nodeOne-&gt;outDegree());
+
+// and naturally, nodes can report on their arcs
+$arcs = $nodeOne-&gt;getNeighbours();
+for ($i=0;$i&lt;sizeof($arcs);$i++) {
+    print(&quot;NodeOne has an arc to &quot; . $arcs[$i]-&gt;getData());
