Seems a bit OTT to have to DL Java and enter a serious of commands to run a script placer. Regardless it works fine.
Probably better to include a bat file to run it, I just made one with the following if anyone else wants to use this:
and just save in same directory as jar as a .bat file.
Note: Searching for map files will use an entire CPU core(25% of a quad core) or more and will take some time to complete(about 15-30 seconds) as it scans the entire root directory. The ability to do a faster, targeted search via typical map directories(WILL NOT DISPLAY ALL MAP FILES THIS WAY) may be available in a later update.15-30 seconds running an entire core @100%? Not trying to bash you or anything but you might want to take some programming courses...
Edit: Just realised you said you're scanning the entire root directory. May I ask why you would release something as inefficient as this? And why do you not just scan map_source, maps etc.? Or even better, read the contents of relevant csv files?
