The variables WGET and LOGGER are the paths to the binaries. Change
them to your system-settings.
DRIFTFILE is the file that holds the version number of the last downloaded DAT-file.
OUTPUT_LOCATION is the location where the DAT-files needs to be saved. When there's a file downloaded,
it will copy this file to the location specified in OUTPUT_CURRENT_LOCATION and rename the dat-file
to latestdat.exe (OUTPUT_CURRENT_LOCATION is prefereably a directory that's shared by Samba and writable - for the temporary-files).
This way, just prepare a sheduled batch-file on your Windows-machine that gets the latest datfiles.
Place the script in your crontab and make sure the cron-user has write/read access to the directory
specified in OUTPUT_LOCATION.
Also, check that you have at least a starting-driftfile to get it going. Create one like this
echo "4323" > DRIFT_FILE (replace with the name of your driftfile)
