packman
One who transports
A packman is a peddler or traveling merchant who carries goods in a pack on his back.
The word is old-fashioned, evoking an era before motorized transport when itinerant sellers walked from town to town: The packman arrived with ribbons and thread.
In video game contexts, Packman (or Pac-Man) refers to the iconic yellow arcade character.
