   \class AppLnk applnk.h
   \brief The AppLnk class represents an application available on the system.
 
     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.
