Over time, this script has saved me dozens of hours that I would have spent manually twiddling with an FTP GUI, or constantly changing directories via an annoying command-line FTP program.
For the -log-file option, a unique log file name is created, using conversion symbols and the date command (the file name includes program name, process ID, date, and time).
Having inserted this command, the program should begin running and start converting your level - this will take a bit of time, especially the converting of lods.
