+To specify where Catalyst should put the temporary files, set the 'uploadtmp'
+option in the Catalyst config. If unset, Catalyst will use the system temp dir.
+
+    __PACKAGE__->config( uploadtmp => '/path/to/tmpdir' );
+
+It is provided a way to have configurable temporary directory.
+If there is no config uploadtmp, system temprary directory will used.
+
+    __PACKAGE__->config( uploadtmp => '/path/to/tmpdir' );

 =head1 DESCRIPTION
 
-This is the Catalyst Request Upload class, which provides a set of accessors to the
-upload data.
+This class provides accessors and methods to handle client upload requests.
 
 =head1 METHODS
 
-=over 4
+=head2 $upload->new
+
+Simple constructor.
+
+=head2 $upload->copy_to
 
-=item $upload->fh
+Copies the temporary file using L<File::Copy>. Returns true for success,
+false for failure.
 
-Opens tempname and returns a C<IO::File> handle.
+     $upload->copy_to('/path/to/target');

+=head2 $upload->fh
 
-    return $fh;
-}
+Opens a temporary file (see tempname below) and returns an L<IO::File> handle.

+=head2 $upload->filename
 
-=item $upload->filename
+Returns the client-supplied filename.
 
-Contains client supplied filename.
+=head2 $upload->headers
 
-=item $upload->link
+Returns an L<HTTP::Headers> object for the request.
 
-Creates a new filename linked to the old filename.  Returns true for
-success, false otherwise.
+=head2 $upload->link_to
 
-    $upload->link('/my/path');
+Creates a hard link to the temporary file. Returns true for success, 
+false for failure.
