\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.
\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
