/*! \page doxywizard_usage Doxywizard usage

Doxywizard is a GUI front-end for configuring and running doxygen. 

When you start doxywizard it will display the main window 
(the actual look depends on the OS used).

\image html doxywizard_main.png "Main window"

The windows shows the steps to take to configure and run doxygen.
The first step is to choose one of the ways to configure doxygen.
<dl>
<dt>Wizard<dd>Click this button to quickly configure the most important 
    settings and leave the rest of the options to their defaults.
<dt>Expert<dd>Click this button to to gain access to the 
    \ref config "full range of configuration options".
<dt>Load<dd>Click this button to load an existing configuration file 
    from disk.
</dl>
Note that you can select multiple buttons in a row, for instance to first 
configure doxygen using the Wizard and then fine tune the settings via 
the Expert.

After doxygen is configured you need to save the configuration as a file
to disk. This second step allows doxygen to use the configuration 
and has the additional advantage that the configuration can be reused 
to run doxygen with the same settings at a later point in time.

Since some configuration options may use relative paths, the next step is
to select a directory from which to run doxygen. This is typically the root
of the source tree and will most of the time already be filled in correctly.

Once the configuration file is saved and the working directory is set, you
can run doxygen based on the selected settings. Do this by pressing the
"Start" button. Once doxygen runs you can cancel it by clicking the same
button again. The output produced by doxygen is captured and shown in a log
window. Once doxygen finishes, the log can be saved as a text file.

<h3>The Wizard Dialog</h3>

If you select the Wizard button in step 1, then a dialog with
a number of tabs will appear.

The fields in the project tab speak for themselves. Once doxygen has finished
the Destination directory is where to look for the results. Doxygen will
put each output format in a separate sub-directory.

\image html doxywizard_page2.png "Wizard dialog: Mode of operating"

The mode tab allows you to select how doxygen will look at your sources.
The default is to only look for things that have been documented. 

You can also select how doxygen should present the results. 
The latter does not affect the way doxygen parses your source code.

\image html doxywizard_page3.png "Wizard dialog: Output to produce"

You can select one or more of the output formats that doxygen should
produce. For HTML and LaTeX there are additional options. 

\image html doxywizard_page4.png "Wizard dialog: Diagrams to generate"

Doxygen can produce a number of diagrams. Using the diagrams tab you
can select which ones to generate. For most diagrams the 
dot tool of the <a href="http://www.graphviz.org">GraphViz</a> package
is needed (if you use the binary packages for MacOSX this
tool is already included).

<h3>Expert dialog</h3>

The Expert dialog has a number of tab fields, one
for each section in the configuration file. Each tab-field
contains a number of lines, one for each configuration option in
that section. 

The kind of input widget depends on the type of the configuration option. 
<ul>
<li>For each boolean option (those options that are answered with YES or 
    NO in the configuration file) there is a check-box. 
<li>For items taking one of a fixed set of values (like 
    \ref cfg_output_language "OUTPUT_LANGUAGE") a combo box is used.
<li>For items taking an integer value from a range, a spinbox is used.
<li>For free form string-type options there is a one line edit field
<li>For options taking a lists of strings, a one line edit field is 
    available, with a `+' button to add this string to the list and 
    a `-' button to remove the selected string from the list. There 
    is also a `*' button that, when pressed, 
    replaces the selected item in the list with the string entered in the 
    edit field. 
<li>For file and folder entries, there are special buttons 
    that start a file selection dialog.
</ul>

The get additional information about the meaning of an option, click
on the "Help" button at the bottom right of the dialog and then on the
item. A tooltip with additional information will appear.

<h3>Menu options</h3>

The GUI front-end has a menu with a couple of useful items

\image html doxywizard_menu.png "File menu"

<dl>
<dt>Open...<dd>This is the same as the "Load" button in the main window
    and allows to open a configuration file from disk.
<dt>Save as..<dd>This is the same as the "Save" button in the main window
    and can be used to save the current configuration settings to disk.
<dt>Recent configurations<dd>Allow to quickly load a recently saved
    configuration.
<dt>Set as default...<dd>Stores the current configuration settings as the
    default to use next time the GUI is started. You will be asked to
    confirm the action.
<dt>Reset...<dd>Restores the factory defaults as the default settings to use.
    You will be asked to confirm the action.
</dl>
