+    \class TQLocalFs qlocalfs.h
+    \brief The TQLocalFs class is an implementation of a
+    TQNetworkProtocol that works on the local file system.
+\if defined(commercial)
+    It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+    \module network
+
+    \ingroup io
+
+    This class is derived from TQNetworkProtocol. TQLocalFs is not
+    normally used directly, but rather through a TQUrlOperator, for
+    example:
+    \code
+    TQUrlOperator op( "file:///tmp" );
+    op.listChildren(); // Asks the server to provide a directory listing
+    \endcode
+
+    This code will only work if the TQLocalFs class is registered; to
+    register the class, you must call qInitNetworkProtocols() before
+    using a TQUrlOperator with TQLocalFs.
+
+    If you really need to use TQLocalFs directly, don't forget
+    to set its TQUrlOperator with setUrl().
