rematch - Edit pairings after the fact
--help This help message
--man A man page
rematch rewrites cards pairing players with the new pairings in ./round.yaml, the file in which the matches produced by pair were reported to the user.This is sometimes necessary if there is a failure in the program to produce the correct pairing, or there is other need to proceed with games not specified by the swiss algorithm. The new Games::Tournament::Card matches are serialized back into ./matches.yaml. The cards originally in ./matches.yaml 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.)
