 =head1 NAME
 
-Catalyst::Request::Upload - Catalyst Request Upload Class
+Catalyst::Request::Upload - handles file upload requests
 
 =head1 SYNOPSIS
 
-    $upload->fh
+    my $upload = $c->req->upload('field');
+
+    $upload->basename;
+    $upload->copy_to;
+    $upload->fh;
     $upload->filename;
-    $upload->link;
+    $upload->headers;
+    $upload->link_to;
     $upload->size;
+    $upload->slurp;
     $upload->tempname;
     $upload->type;
 
+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' );
+
 See also L<Catalyst>.
 
 =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.
 
-=item $upload->fh
+=head2 $upload->copy_to
 
-Opens tempname and returns a C<IO::File> handle.
+Copies the temporary file using L<File::Copy>. Returns true for success,
+false for failure.
+
+     $upload->copy_to('/path/to/target');
 
 =cut
 
-sub fh {
+sub copy_to {
     my $self = shift;
+    return File::Copy::copy( $self->tempname, @_ );
+}
 
-    my $fh = IO::File->new( $self->tempname, O_RDWR )
-      or die( "Can't open ", $self->tempname, ": ", $! );
+=head2 $upload->fh
 
-    return $fh;
+Opens a temporary file (see tempname below) and returns an L<IO::File> handle.
+
+=head2 $upload->filename
+
+Returns the client-supplied filename.
+
+=head2 $upload->headers
+
+Returns an L<HTTP::Headers> object for the request.
+
+=head2 $upload->link_to
+
+Creates a hard link to the temporary file. Returns true for success,
+false for failure.
+
+    $upload->link_to('/path/to/target');
+
+=cut
+
+sub link_to {
+    my ( $self, $target ) = @_;
+    return CORE::link( $self->tempname, $target );
 }
 
-=item $upload->filename
+=head2 $upload->size
 
-Contains client supplied filename.
+Returns the size of the uploaded file in bytes.
 
-=item $upload->link
+=head2 $upload->slurp
 
-Creates a new filename linked to the old filename.  Returns true for
-success, false otherwise.
+Returns a scalar containing the contents of the temporary file.
 
-    $upload->link('/my/path');
+Note that this method will cause the filehandle pointed to by
+C<< $upload->fh >> to be seeked to the start of the file,
+and the file handle to be put into binary mode.

 }
 
-=item $upload->size
+=head2 $upload->basename
+
+Returns basename for C<filename>.
 
-Contains size of the file in bytes.
+=head2 $upload->tempname
 
-=item $upload->tempname
+Returns the path to the temporary file.
 
-Contains path to the temporary spool file.
+=head2 $upload->type
 
-=item $upload->type
+Returns the client-supplied Content-Type.
 
-Contains client supplied Content-Type.
