This program is intended to support the use of a tournament file as
a database. It should be called from Chaos itself to update the
DWZ numbers in a previously saved tournament file.
Usage: UpdateRatings [filename]
<filename> is the name of a database file. This argument is not
required if you have RequestFile or a similar command: The script
brings up a requester to select a file in that case. (The commands
name can be changed below in the script. However, it must write the
filename to stdout.) I don't know, if RequestFile is available below
of Workbench 39, sorry.
Important notes:
- This script must not be used, if Chaos isn't ready to receive
commands. Chaos shows that it is ready by enabling the menu bar in
its main window. The best way to ensure this, is to call it from
the menu bar itself by including the script into s/ChaosMenu.
- It is assumed, that the player names in the tournament and in the
database file are identical. The best way to ensure this is, to
use the menu item "Import".
