* Writing support added to the SummaryInformation and DocumentSummaryInformation classes. These classes now have methods for setting and removing properties. Coherent extensions are:

** Documentation section about writing standard properties added to the HPSF HOW-TO.
** Example application added showing how to modify the document summary information.
** Testcases added for testing modifying summary information and document summary information.
** PropertySetFactory extended to create SummaryInformation and DocumentSummaryInformation instances.

* Added MutablePropertySet.write(DirectoryEntry, String) to ease writing a property set to a POI filesystem document.

* Improved codepage handling.

* Bug fixed: Integral values were read and written as unsigned instead of signed.

* Reworked the mapping between variant types and Java types: Variant.VT_I4 is mapped to Integer now and Variant.VT_I8 to Long. This might cause incompatibilities if you are doing low-level HPSF programming. 

* Changed SectionIDMap.DOCUMENT_SUMMARY_INFORMATION_ID from a byte[] to a byte[][] in order to contain the format ID of the first and the second section. This is an incompatible change!

* Added PropertySet.getFirstSection(). This method is similar to getSingleSection() won't choke if the property set has more than one section.

* Support for low-level reading and writing of Variant.VT_I8 type properties added.

* Unnecessary casts removed.

* Poibrowser's display format changed slightly.

+
+    <p>The first thing you should understand is that a Microsoft Office file is
+     not one large bunch of bytes but has an internal filesystem structure with
+     files and directories. You can access these files and directories using
+     the <link href="../poifs/index.html">POI filesystem (POIFS)</link>
+     provides. A file or document in a POI filesystem is also called a
+     <strong>stream</strong> - The properties of, say, an Excel document are
+     stored apart of the actual spreadsheet data in separate streams. The good
+     new is that this separation makes the properties independent of the
+     concrete Microsoft Office file. In the following text we will always say
+     "POI filesystem" instead of "Microsoft Office file" because a POI
+     filesystem is not necessarily created by or for a Microsoft Office
+     application, because it is shorter, and because we want to avoid the name

+   <section><title>Writing Standard Properties</title>
+
+    <note>This section explains how to <strong>write standard
+      properties</strong>. HPSF provides some high-level classes and methods
+     which make writing of standard properties easy. They are based on the
+     low-level writing functions explained in <link href="#sec4">another 
+      section</link>.</note>
+
+    <p>As explained above, standard properties are located in the summary
+     information and document summary information streams of typical POI
+     filesystems. You have already learned about the classes
+     <code>SummaryInformation</code> and
+     <code>DocumentSummaryInformation</code> and their <code>get...()</code>
+     methods for reading standard properties. These classes also provide
+     <code>set...()</code> methods for writing properties.</p>
+
+    <p>After setting properties in <code>SummaryInformation</code> or
+     <code>DocumentSummaryInformation</code> you have to write them to a disk
+     file. The following sample program shows how you can</p>
+
+    <ol>
+     <li>read a disk file into a POI filesystem,</li>
+     <li>read the document summary information from the POI filesystem,</li>
+     <li>set a property to a new value,</li>
+     <li>write the modified document summary information back to the POI
+      filesystem, and</li>
+     <li>write the POI filesystem to a disk file.</li>
+    </ol>
+
+    <p>The complete source code of this program is available as
+     <em>ModifyDocumentSummaryInformation.java</em> in the <em>examples</em>
+     section of the POI source tree.</p>
+
+    <note>Dealing with the summary information stream is analogous to handling
+     the document summary information and therefore does not need to be
+     explained here in detailed. See the HPSF API documentation to learn about
+     the <code>set...()</code> methods of the class
+     <code>SummaryInformation</code>.</note>
+
+    <p>The first step is to read the POI filesystem into memory:</p>
+
+    <source>InputStream is = new FileInputStream(poiFilesystem);
+POIFSFileSystem poifs = new POIFSFileSystem(is);
+is.close();</source>
+
+    <p>The code snippet above assumes that the variable
+     <code>poiFilesystem</code> holds the name of a disk file. It reads the
+     file from an input stream and creates a <code>POIFSFileSystem</code>
+     object in memory. After having read the file, the input stream should be
+     closed as shown.</p>
+
+    <p>In order to read the document summary information stream the application
+     must open the element <em>\005DocumentSummaryInformation</em> in the POI
+     filesystem's root directory. However, the POI filesystem does not
+     necessarily contain a document summary information stream, and the
+     application should be able to deal with that situation. The following
+     code does so by creating a new <code>DocumentSummaryInformation</code> if
+     there is none in the POI filesystem:</p>
+
+    <source>DirectoryEntry dir = poifs.getRoot();
+DocumentSummaryInformation dsi;
+try
+{
+    DocumentEntry dsiEntry = (DocumentEntry)
+        dir.getEntry(DocumentSummaryInformation.DEFAULT_STREAM_NAME);
+    DocumentInputStream dis = new DocumentInputStream(dsiEntry);
+    PropertySet ps = new PropertySet(dis);
+    dis.close();
+    dsi = new DocumentSummaryInformation(ps);
+}
+catch (FileNotFoundException ex)
+{
+    /* There is no document summary information. We have to create a
+     * new one. */
+    dsi = PropertySetFactory.newDocumentSummaryInformation();
+}
+    </source>
+
+    <p>In the source code above the statement</p>
+
+    <source>DirectoryEntry dir = poifs.getRoot();</source>
+
+    <p>gets hold of the POI filesystem's root directory as a
+     <code>DirectoryEntry</code>. The <code>getEntry()</code> method of this
+     class is used to access a file or directory entry in a directory. However,
+     if the file to be opened does not exist, a
+     <code>FileNotFoundException</code> will be thrown. Therefore opening the
+     document summary information entry should be done in a <code>try</code>
+     block:</p>
+
+    <source>    DocumentEntry dsiEntry = (DocumentEntry)
+        dir.getEntry(DocumentSummaryInformation.DEFAULT_STREAM_NAME);</source>
+
+    <p><code>DocumentSummaryInformation.DEFAULT_STREAM_NAME</code> represents
+     the string "\005DocumentSummaryInformation", i.e. the standard name of a
+     document summary information stream. If this stream exists, the
+     <code>getEntry()</code> method returns a <code>DocumentEntry</code>. To
+     read the <code>DocumentEntry</code>'s contents, create a
+     <code>DocumentInputStream</code>:</p>
+
+    <source>     DocumentInputStream dis = new DocumentInputStream(dsiEntry);</source>
+
+    <p>Up to this point we have used POI's <link
+      href="../poifs/index.html">POIFS component</link>. Now HPSF enters the
+     stage. A property set is created from the input stream's data:</p>
+
+    <source>    PropertySet ps = new PropertySet(dis);
+    dis.close();
+    dsi = new DocumentSummaryInformation(ps);    </source>
+
+    <p>If the data really constitutes a property set, a
+     <code>PropertySet</code> object is created. Otherwise a
+     <code>NoPropertySetStreamException</code> is thrown. After having read the
+     data from the input stream the latter should be closed.</p>
+
+    <p>Since we know - or at least hope - that the stream named
+     "\005DocumentSummaryInformation" is not just any property set but really
+     contains the document summary information, we try to create a new
+     <code>DocumentSummaryInformation</code> from the property set. If the
+     stream is not document summary information stream the sample application
+     fails with a <code>UnexpectedPropertySetTypeException</code>.</p>
+
+    <p>If the POI document does not contain a document summary information
+     stream, we can create a new one in the <code>catch</code> clause. The
+     <code>PropertySetFactory</code>'s method
+     <code>newDocumentSummaryInformation()</code> establishes a new and empty
+     <code>DocumentSummaryInformation</code> instance:</p>
+
+    <source>    dsi = PropertySetFactory.newDocumentSummaryInformation();</source>
+
+    <p>Whether we read the document summary information from the POI filesystem
+     or created it from scratch, in either case we now have a
+     <code>DocumentSummaryInformation</code> instance we can write to. Writing
+     is quite simple, as the following line of code shows:</p>
+
+    <source>dsi.setCategory("POI example");</source>
+
+    <p>This statement sets the "category" property to "POI example". Any
+     former "category" value will be lost. If there hasn't been a "category"
+     property yet, a new one will be created.</p>
+
+    <p><code>DocumentSummaryInformation</code> of course has methods to set the
+     other standard properties, too - look into the API documentation to see
+     all of them.</p>
+
+    <p>Once all properties are set as needed, they should be stored into the
+     file on disk. The first step is to write the
+     <code>DocumentSummaryInformation</code> into the POI filesystem:</p>
+
+    <source>dsi.write(dir, DocumentSummaryInformation.DEFAULT_STREAM_NAME);</source>
+
+    <p>The <code>DocumentSummaryInformation</code>'s <code>write()</code>
+     method takes two parameters: The first is the <code>DirectoryEntry</code>
+     in the POI filesystem, the second is the name of the stream to create in
+     the directory. If this stream already exists, it will be overwritten.</p>
+
+    <note>If you not only modified the document summary information but also
+     the summary information you have to write both of them to the POI
+     filesystem.</note>
+
+    <p>Still the POI filesystem is a data structure in memory only and must be
+     written to a disk file to make it permanent. The following lines write
+     back the POI filesystem to the file it was read from before. Please note
+     that in production-quality code you should never write directly to the
+     origin file, because in case of an error everything would be lost. Here it
+     is done this way to keep the example short.</p>

+     <p>If you compare the source code excerpts above with the file containing
+      the full source code, you will notice that I left out some following
+      lines of code. The are dealing with the special topic of custom
+      properties.</p>

+CustomProperties customProperties = dsi.getCustomProperties();
+if (customProperties == null)
+    customProperties = new CustomProperties();
+
+/* Insert some custom properties into the container. */

+customProperties.put("Sample Boolean", new Boolean(true));
+customProperties.put("Sample Date", new Date());
+
+/* Read a custom property. */
+Object value = customProperties.get("Sample Number");
+
+/* Write the custom properties back to the document summary
+ * information. */
+dsi.setCustomProperties(customProperties);</source>
+
+     <p>Custom properties are properties the user can define himself. Using for
+      example Microsoft Word he can define these extra properties and give
+      each of them a <strong>name</strong>, a <strong>type</strong> and a
+      <strong>value</strong>. The custom properties are stored in the document
+      information summary along with the standard properties.</p>
+
+     <p>The source code example shows how to retrieve the custom properties
+      as a whole from a <code>DocumentSummaryInformation</code> instance using
+      the <code>getCustomProperties()</code> method. The result is a
+      <code>CustomProperties</code> instance or <code>null</code> if no
+      user-defined properties exist.</p>
+
+     <p>Since <code>CustomProperties</code> implements the <code>Map</code>
+      interface you can read and write properties with the usual
+      <code>Map</code> methods. However, <code>CustomProperties</code> poses
+      some restrictions on the types of keys and values.</p>
+
+     <ul>
+      <li>The <strong>key</strong> is a string.</li>
+      <li>The <strong>value</strong> is one of <code>String</code>,
+       <code>Boolean</code>, <code>Long</code>, <code>Integer</code>,
+       <code>Short</code>, or <code>java.util.Date</code>.</li>
+     </ul>
+
+     <p>The <code>CustomProperties</code> class has been designed for easy
+      access using just keys and values. The underlying Microsoft-specific
+      custom properties data structure is more complicated. However, it does
+      not provide noteworthy additional benefits. It is possible to have
+      multiple properties with the same name or properties without a
+      name at all. When reading custom properties from a document summary
+      information stream, the <code>CustomProperties</code> class ignores
+      properties without a name and keeps only the "last" (whatever that means)
+      of those properties having the same name. You can find out whether a
+      <code>CustomProperties</code> instance dropped any properties with the
+      <code>isPure()</code> method.</p>
+
+     <p>You can read and write the full spectrum of custom properties with
+      HPSF's low-level methods. They are explained in the <link
