Usage:
|
|
$argv0 [options] -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 results of chess games and stores their PGN
|
|
files, assuming that all the games were played by the same pair of
|
|
players on tour <num> of the tournament. Each game should be
|
|
available at the corresponding <url> (lichess.org). The PGN files
|
|
are sorted by their timestamps, unless '-u' is set. The date of
|
|
games is assigned to that of the game closing the tour, i.e., the
|
|
last one.
|
|
|
|
The second form shows this help output. The third form shows version
|
|
information.
|
|
|
|
Options:
|
|
-a Add current games to existing games
|
|
-c Clean up existing games before adding
|
|
-u Don't sort games by their timestamps
