   \class AppLnk applnk.h
   \brief The AppLnk class represents an application available on the system.
 
-  Information about applications are stored in Qtopia as ".desktop" files.
-  When read, these files are stored as AppLnk objects.
+    Every Qtopia application \e app has a corresponding \e app.desktop
+    file. When one of these files is read its data is stored as an
+    AppLnk object.
+
+    The AppLnk class introduces some Qtopia-specific concepts, and
+    provides a variety of functions, as described in the following
+    sections.
+    \tableofcontents
+
+    \target Types
+    \section1 Types
+
+    Every AppLnk object has a \e type. For applications, games and
+    settings the type is \c Application; for documents the
+    type is the document's MIME type.
+
+    \target files-and-links
+    \section1 Files and Links
+
+    When you create an AppLnk (or more likely, a \link doclnk.html
+    DocLnk\endlink), you don't deal directly with filenames in the
+    filesystem. Instead you do this:
+    \code
+    DocLnk d;
+    d.setType("text/plain");
+    d.setName("My Nicely Named Document / Whatever"); // Yes, "/" is legal.
+    \endcode
+    At this point, the file() and linkFile() are unknown. Normally
+    this is uninteresting, and the names become automatically known,
+    and more importantly, becomes reserved, when you ask what they are:
+
+    \code
+    QString fn = d.file();
+    \endcode
+    This invents a filename, and creates the file on disk (an empty
+    reservation file) to prevent the name being used by another
+    application.
+
+    In some circumstances, you don't want to create the file if it
+    doesn't already exist (e.g. in the Document tab, some of the \link
+    doclnk.html DocLnk\endlink objects represented by icons are
+    DocLnk's created just for that view - they don't have
+    corresponding \c .desktop files. To avoid littering empty
+    reservation files around, we check in a few places to see whether
+    the file really needs to exist).
+
+    \section1 Functionality
+
+    AppLnk objects are created by calling the constructor with the
+    name of a \e .desktop file. The object can be checked for validity
+    using isValid().
+
+    The following functions are used to set or retrieve information
+    about the application:
+    \table
+    \header \i Get Function \i Set Function \i Short Description
+    \row \i \l name()	    \i \l setName()    \i application's name
+    \row \i \l pixmap()     \i \e none	    \i application's icon
+    \row \i \l bigPixmap()  \i \e none	    \i application's large icon
+    \row \i \e none	    \i setIcon()    \i sets the icon's filename
+    \row \i \l type() 	    \i \l setType()    \i see \link #Types Types\endlink above
+    \row \i \l rotation()   \i \e none	    \i 0, 90, 180 or 270 degrees
+    \row \i \l comment()    \i \l setComment() \i text for the Details dialog
+    \row \i \l exec()	    \i \l setExec()    \i executable's filename
+    \row \i \l file()	    \i \e none	    \i document's filename
+    \row \i \l linkFile()   \i \l setLinkFile()	\i \e .desktop filename
+    \row \i \l mimeTypes()  \i \e none	    \i the mime types the application can view or edit
+    \row \i \l categories() \i \l setCategories()	\i \e{see the function descriptions}
+    \row \i \l fileKnown()  \i \e none	    \i see \link
+#files-and-links Files and Links\endlink above
+    \row \i \l linkFileKnown() \i \e none	    \i see \link
+#files-and-links Files and Links\endlink above
+    \row \i \l property()   \i \l setProperty()	\i any AppLnk property
+    can be retrieved or set (if writeable) using these
+    \endtable
+
+    To save an AppLnk to disk use writeLink(). To execute the
+    application that the AppLnk object refers to, use execute().
+
+    AppLnk's can be deleted from disk using removeLinkFile(). To
+    remove both the link and the application's executable use
+    removeFiles().
+
+    Icon sizes can be globally changed (but only for AppLnk objects
+    created after the calls) with setSmallIconSize() and
+    setBigIconSize().
