markCards - Mark cards with results of matches
markCards
--help This help message
--man A man page
markCards tallies results from $scores/$round.yaml, marking the Games::Tournament::Card cards from matches.yaml with them. It then serializes the cards back into matches.yaml. The unmarked cards are preserved in matches.yaml.bak.
The configuration file, ../league.yaml, holds the value of $scores, and $round is the directory name in which the command is run and where matches.yaml and player.yaml, a file of serialized player objects, exist. (The name must be a round number.)
