What do colons mean in a subroutine definition?

Question

In this source code i found this sub definition.

sub upload_file : Chained( 'base' ) : PathPart( 'upload-file' ) : Args( 0 ){

I don't understand what means those : colons and parameters. Can anybody point me to some docs?

:Chained, :PathPArt and :Args are attributes provided by Catalyst.

Huh... accpeting (ofc) - but the "subroutine attributes" are totally new thing for me. Just found this nice answer about them: (http://stackoverflow.com/a/987293/632407) – novacik Nov 19 '13 at 10:51
