Store a chess game played on lichess.org
Usage:
$argv0 -t <num> <url>
$argv0 -h
$argv0 -v
Put the script under the root directory of your repository or set
inner variable REPO_DIR to it. If the tournament is not the last one
(default), store its sub-directory in inner variable TOURNAMENT.
The first form fills the result of a chess game and stores its PGN
file, assuming that the game is available at <url> (lichess.org) and
corresponds to tournament tour <num>. The second form shows this
help output. The third form shows version information.
