-    \example help/simpletextviewer
-    \title Simple Text Viewer Example
-
-    \brief The Simple Text Viewer example shows how to use \QA as a customized
-    help viewer for your application.
-
-    \image simpletextviewer-example.png
-
-    This is done in two stages. Firstly, documentation is created and \QA
-    is customized; secondly, the functionality to launch and control
-    \QA is added to the application.
-
-    The Simple Text Viewer application lets the user select and view
-    existing files.
-
-    The application provides its own custom documentation that is
-    available from the \gui Help menu in the main window's menu bar
-    or by clicking the \gui Help button in the application's find file
-    dialog.
-
-    The example consists of four classes:
-
-    \list
-        \li \c Assistant provides functionality to launch \QA.
-        \li \c MainWindow is the main application window.
-        \li \c FindFileDialog allows the user to search for
-           files using wildcard matching.
-        \li \c TextEdit provides a rich text browser that makes
-           sure that images referenced in HTML documents are
-           displayed properly.
-    \endlist
-
-    \note We will only comment on the parts of the implementation
-    that are relevant to the main issue, that is making Qt Assistant
-    act as a customized help viewer for our Simple Text Viewer
-    application.
-
-    \section1 Creating Documentation and Customizing \QA
-
-    How to create the actual documentation in the form of HTML pages is
-    not in the scope of this example. In general, HTML pages can either
-    be written by hand or generated with the help of documentation tools
-    like qdoc or Doxygen. For the purposes of this example we assume that
-    the HTML files have already been created. So, the only thing that
-    remains to be done is to tell \QA how to structure and display the
-    help information.
-
-    \section2 Organizing Documentation for \QA
-
-    Plain HTML files only contain text or documentation about specific topics,
-    but they usually include no information about how several HTML documents
-    relate to each other or in which order they are supposed to be read.
-    What is missing is a table of contents along with an index to access
-    certain help contents quickly, without having to browse through a lot
-    of documents in order to find a piece of information.
-
-    To organize the documentation and make it available for \QA, we have
-    to create a Qt help project (.qhp) file. The first and most important
-    part of the project file is the definition of the namespace. The namespace
-    has to be unique and will be the first part of the page URL in \QA.
-    In addition, we have to set a virtual folder which acts as a common
-    folder for documentation sets. This means, that two documentation sets
-    identified by two different namespaces can cross reference HTML files
-    since those files are in one big virtual folder. However, for this
-    example, we'll only have one documentation set available, so the
-    virtual folder name and functionality are not important.
-
-    \code
-    <?xml version="1.0" encoding="UTF-8"?>
-    <QtHelpProject version="1.0">
-      <namespace>com.trolltech.examples.simpletextviewer</namespace>
-      <virtualFolder>doc</virtualFolder>
-    \endcode
-
-    The next step is to define the filter section. A filter section
-    contains the table of contents, indices and a complete list of
-    all documentation files, and can have any number of filter attributes
-    assigned to it. A filter attribute is an ordinary string which can
-    be freely chosen. Later in \QA, users can then define a custom
-    filter referencing those attributes. If the attributes of a filter
-    section match the attributes of the custom filter the documentation
-    will be shown, otherwise \QA will hide the documentation.
-
-    Again, since we'll only have one documentation set, we do not need
-    the filtering functionality of \QA and can therefore skip the
-    filter attributes.
-
-    Now, we build up the table of contents. An item in the table is
-    defined by the \c section tag which contains the attributes for the
-    item title as well as link to the actual page. Section tags can be
-    nested infinitely, but for practical reasons it is not recommended
-    to nest them deeper than three or four levels. For our example we
-    want to use the following outline for the table of contents:
-
-    \list
-    \li Simple Text Viewer
-      \list
-      \li Find File
-        \list
-        \li File Dialog
-        \li Wildcard Matching
-        \li Browse
-        \endlist
-      \li Open File
-      \endlist
-    \endlist
-
-    In the help project file, the outline is represented by:
-
-    \code
-     <filterSection>
-       <toc>
-         <section title="Simple Text Viewer" ref="index.html">
-           <section title="Find File" ref="./findfile.html">
-             <section title="File Dialog" ref="./filedialog.html"></section>
-             <section title="Wildcard Matching" ref="./wildcardmatching.html"></section>
-             <section title="Browse" ref="./browse.html"></section>
-           </section>
-           <section title="Open File" ref="./openfile.html"></section>
-         </section>
-       </toc>
-    \endcode
-
-    After the table of contents is defined, we will list all index keywords:
-
-    \code
-        <keywords>
-          <keyword name="Display" ref="./index.html"/>
-          <keyword name="Rich text" ref="./index.html"/>
-          <keyword name="Plain text" ref="./index.html"/>
-          <keyword name="Find" ref="./findfile.html"/>
-          <keyword name="File menu" ref="./findfile.html"/>
-          <keyword name="File name" ref="./filedialog.html"/>
-          <keyword name="File dialog" ref="./filedialog.html"/>
-          <keyword name="File globbing" ref="./wildcardmatching.html"/>
-          <keyword name="Wildcard matching" ref="./wildcardmatching.html"/>
-          <keyword name="Wildcard syntax" ref="./wildcardmatching.html"/>
-          <keyword name="Browse" ref="./browse.html"/>
-          <keyword name="Directory" ref="./browse.html"/>
-          <keyword name="Open" ref="./openfile.html"/>
-          <keyword name="Select" ref="./openfile.html"/>
-        </keywords>
-    \endcode
-
-    As the last step, we have to list all files making up the documentation.
-    An important point to note here is that all files have to listed, including
-    image files, and even stylesheets if they are used.
-
-    \code
-        <files>
-          <file>browse.html</file>
-          <file>filedialog.html</file>
-          <file>findfile.html</file>
-          <file>index.html</file>
-          <file>intro.html</file>
-          <file>openfile.html</file>
-          <file>wildcardmatching.html</file>
-          <file>images/browse.png</file>
-          <file>images/*.png</file>
-        </files>
-      </filterSection>
-    </QtHelpProject>
-    \endcode
-
-    The help project file is now finished. If you want to see the resulting
-    documentation in \QA, you have to generate a Qt compressed help file
-    out of it and register it with the default help collection of \QA.
-
-    \code
-    qhelpgenerator simpletextviewer.qhp -o simpletextviewer.qch
-    assistant -register simpletextviewer.qch
-    \endcode
-
-    If you start \QA now, you'll see the Simple Text Viewer documentation
-    beside the Qt documentation. This is OK for testing purposes, but
-    for the final version we want to only have the Simple Text Viewer
-    documentation in \QA.
-
-    \section2 Customizing \QA
-
-    The easiest way to make \QA only display the Simple Text Viewer
-    documentation is to create our own help collection file. A collection
-    file is stored in a binary format, similar to the compressed help file,
-    and generated from a help collection project file (*.qhcp). With
-    the help of a collection file, we can customize the appearance and even
-    some functionality offered by \QA.
-
-    At first, we change the window title and icon. Instead of showing "\QA"
-    it will show "Simple Text Viewer", so it is much clearer for the user
-    that the help viewer actually belongs to our application.
-
-    \code
-    <?xml version="1.0" encoding="UTF-8"?>
-    <QHelpCollectionProject version="1.0">
-    <assistant>
-        <title>Simple Text Viewer</title>
-        <applicationIcon>images/handbook.png</applicationIcon>
-        <cacheDirectory>Trolltech/SimpleTextViewer</cacheDirectory>
-    \endcode
-
-    The \c cacheDirectory tag specifies a subdirectory of the users
-    data directory (see the
-    \l{Customizing Qt Assistant#Qt Help Collection Files}{Qt Help Collection Files})
-    where the cache file for the full text search or the settings file will
-    be stored.
-
-    After this, we set the page displayed by \QA when launched for the very
-    first time in its new configuration. The URL consists of the namespace
-    and virtual folder defined in the Qt help project file, followed by the
-    actual page file name.
-
-    \code
-        <startPage>qthelp://com.trolltech.examples.simpletextviewer/doc/index.html</startPage>
-    \endcode
-
-    Next, we alter the name of the "About" menu item to "About Simple
-    Text Viewer". The contents of the \gui{About} dialog are also changed
-    by specifying a file where the about text or icon is taken from.
-
-    \code
-        <aboutMenuText>
-            <text>About Simple Text Viewer</text>
-        </aboutMenuText>
-        <aboutDialog>
-            <file>about.txt</file>
-            <icon>images/icon.png</icon>
-        </aboutDialog>
-    \endcode
-
-    \QA offers the possibility to add or remove documentation via its
-    preferences dialog. This functionality is helpful when using \QA
-    as the central help viewer for more applications, but in our case
-    we want to actually prevent the user from removing the documentation.
-    So, we hide the \gui Documentation tab in the \gui Preferences dialog.
-
-    Since the address bar is not really relevant in such a small
-    documentation set we switch it off as well. By having just one filter
-    section, without any filter attributes, we can also disable the filter
-    functionality of \QA, which means that the filter page and the filter
-    toolbar will not be available.
-
-    \code
-        <enableDocumentationManager>false</enableDocumentationManager>
-        <enableAddressBar>false</enableAddressBar>
-        <enableFilterFunctionality>false</enableFilterFunctionality>
-    </assistant>
-    \endcode
-
-    For testing purposes, we already generated the compressed help file
-    and registered it with \QA's default help collection. With the
-    following lines we achieve the same result. The only and important
-    difference is that we register the compressed help file, not in
-    the default collection, but in our own collection file.
-
-    \code
-      <docFiles>
-        <generate>
-            <file>
-                <input>simpletextviewer.qhp</input>
-                <output>simpletextviewer.qch</output>
-                </file>
-            </generate>
-        <register>
-            <file>simpletextviewer.qch</file>
-            </register>
-        </docFiles>
-    </QHelpCollectionProject>
-    \endcode
-
-    As the last step, we have to generate the binary collection file
-    out of the help collection project file. This is done by running the
-    \c qcollectiongenerator tool.
-
-    \code
-    qcollectiongenerator simpletextviewer.qhcp -o simpletextviewer.qhc
-    \endcode
-
-    To test all our customizations made to \QA, we add the collection
-    file name to the command line:
-
-    \code
-    assistant -collectionFile simpletextviewer.qhc
-    \endcode
-
-    \section1 Controlling \QA via the Assistant Class
-
-    We will first take a look at how to start and operate \QA from a
-    remote application. For that purpose, we create a class called
-    \c Assistant.
-
-    This class provides a public function that is used to show pages
-    of the documentation, and one private helper function to make sure
-    that \QA is up and running.
-
-    Launching \QA is done in the function \c startAssistant() by simply
-    creating and starting a QProcess. If the process is already running,
-    the function returns immediately. Otherwise, the process has
-    to be set up and started.
-
-    \snippet simpletextviewer/assistant.cpp 2
-
-    To start the process we need the executable name of \QA as well as the
-    command line arguments for running \QA in a customized mode. The
-    executable name is a little bit tricky since it depends on the
-    platform, but fortunately it is only different on Mac OS X.
-
-    The displayed documentation can be altered using the \c -collectionFile
-    command line argument when launching \QA. When started without any options,
-    \QA displays a default set of documentation. When Qt is installed,
-    the default documentation set in \QA contains the Qt reference
-    documentation as well as the tools that come with Qt, such as Qt
-    Designer and \c qmake.
-
-    In our example, we replace the default documentation set with our
-    custom documentation by passing our application-specific collection
-    file to the process's command line options.
-
-    As the last argument, we add \c -enableRemoteControl, which makes \QA
-    listen to its \c stdin channel for commands, such as those to display
-    a certain page in the documentation.
-    Then we start the process and wait until it is actually running. If,
-    for some reason \QA cannot be started, \c startAssistant() will return
-    false.
-
-    The implementation for \c showDocumentation() is now straightforward.
-    Firstly, we ensure that \QA is running, then we send the request to
-    display the \a page via the \c stdin channel of the process. It is very
-    important here that the command is terminated by the '\\0' character
-    followed by an end of line token to flush the channel.
-
-    \snippet simpletextviewer/assistant.cpp 1
-
-    Finally, we make sure that \QA is terminated properly in the case that
-    the application is shut down. The destructor of QProcess kills the
-    process, meaning that the application has no possibility to do things
-    like save user settings, which would result in corrupted settings files.
-    To avoid this, we ask \QA to terminate in the destructor of the
-    \c Assistant class.
-
-    \snippet simpletextviewer/assistant.cpp 0
-
-    \section1 MainWindow Class
-
-    \image simpletextviewer-mainwindow.png
-
-    The \c MainWindow class provides the main application window with
-    two menus: the \gui File menu lets the user open and view an
-    existing file, while the \gui Help menu provides information about
-    the application and about Qt, and lets the user open \QA to
-    display the application's documentation.
-
-    To be able to access the help functionality, we initialize the
-    \c Assistant object in the \c MainWindow's constructor.
-
-    \snippet simpletextviewer/mainwindow.cpp 0
-    \dots
-    \snippet simpletextviewer/mainwindow.cpp 1
-
-    Then we create all the actions for the Simple Text Viewer application.
-    Of special interest is the \c assistantAct action accessible
-    via the \key{F1} shortcut or the \gui Help > \gui {Help Contents} menu item.
-    This action is connected to the \c showDocumentation() slot of
-    the \c MainWindow class.
-
-    \snippet simpletextviewer/mainwindow.cpp 4
-    \dots
-    \snippet simpletextviewer/mainwindow.cpp 5
-
-    In the \c showDocumentation() slot, we call the \c showDocumentation()
-    function of the \c Assistant class with the URL of home page of the
-    documentation.
-
-    \snippet simpletextviewer/mainwindow.cpp 3
-
-    Finally, we must reimplement the protected QWidget::closeEvent()
-    event handler to ensure that the application's \QA instance is
-    properly closed before we terminate the application.
-
-    \snippet simpletextviewer/mainwindow.cpp 2
-
-    \section1 FindFileDialog Class
-
-    \image simpletextviewer-findfiledialog.png
-
-    The Simple Text Viewer application provides a find file dialog
-    allowing the user to search for files using wildcard matching. The
-    search is performed within the specified directory, and the user
-    is given an option to browse the existing file system to find the
-    relevant directory.
-
-    In the constructor we save the references to the \c Assistant
-    and \c QTextEdit objects passed as arguments. The \c Assistant
-    object will be used in the \c FindFileDialog's \c help() slot,
-    as we will see shortly, while the QTextEdit will be used in the
-    dialog's \c openFile() slot to display the chosen file.
-
-    \snippet simpletextviewer/findfiledialog.cpp 0
-    \dots
-    \snippet simpletextviewer/findfiledialog.cpp 1
-
-    The most relevant member to observe in the \c FindFileDialog
-    class is the private \c help() slot. The slot is connected to the
-    dialog's \gui Help button, and brings the current \QA instance
-    to the foreground with the documentation for the dialog by
-    calling \c Assistant's \c showDocumentation() function.
-
-    \snippet simpletextviewer/findfiledialog.cpp 2
-
-    \section1 Summary
-
-    In order to make \QA act as a customized help tool for
-    your application, you must provide your application with a
-    process that controls \QA in addition to a custom help collection
-    file including Qt compressed help files.
-
-    For  more information about the options and settings available to
-    applications that use \QA as a custom help viewer, see
-    \l{Customizing Qt Assistant}.

-
-        <p>
-        Most command shells such as bash or cmd.exe support "file
-        globbing", the ability to identify a group of files by using
-        wildcards. 
-
-        <br />
-        <br />
-        <table align="center" cellpadding="2" cellspacing="1" border="0" width="100%">
-        <tr valign="top" bgcolor="#f0f0f0">
-        <td><center><img src="images/wildcard.png" /></center></td>
-        </tr>
-        </table>
-
-        <br />
-        <br />
-        <p>
-        Wildcard matching provides four features:     
-        </p>   
-
-	<ul>
-	    <li>Any character represents itself apart from those
-	    mentioned below. Thus 'c' matches the character 'c'.
-            </li>
-	    <li>The '?' character matches any single character.</li>
-	    <li>The '*' matches zero or more of any characters.</li>
-	    <li>Sets of characters can be represented in square brackets. 
-                Within the character class, like outside, backslash 
-                has no special meaning.
-	    </li>
-	</ul>
-
-        <p>
-        For example we could identify HTML files with
-        <code>*.html</code>. This will match zero or more characters
-        followed by a dot followed by 'h', 't', 'm' and 'l'.
-        </p>
-
-        <br />
