Simple command line tool for tinkering with regions after world generation.
At this moment, able to export titan/demon raw data, as well as all raw tags which get loaded.
Able to insert new tags as well. As a result, able to break save games if you're not careful.
Now can automagically synchronize with a regions raws.

Drop in the DF folder, open a command prompt, and run it.

Usage:
dfworldtinker <region> <export|import> <file>
Examples:
dfworldtinker region1 export -
dfworldtinker 1 export exportfile.txt
dfworldtinker 1 forceexport exportfile.txt
dfworldtinker 1 import modifiedfile.txt
dfworldtinker 1 forceimport modifiedfile.txt
dfworldtinker 1 sync
dfworldtinker 1 forcesync

All parameters are required.
Commands can now be preceded with "force" to force the program to continue even if there are errors.
Regions can either be entered with their full name, or just as their number for convenience.
Entering a single dash for the input/output file reads from or writes to terminal.
If no commands given, enters a very simple interactive mode.
The sync command will open raws in the savegame's path, and import tags from it. See forum.

Only able to edit non-compressed saved games and regions. See your init file.
