The Packmode Preprocessor will change the script to only be executed if a certain packmode is enabled in the packmode config file
You call the Packmode Preprocessor by adding
#packmode mode(s) to your script file, with
mode(s) being the pack mode(s) you want the script to run in
#packmode normal expert would enable the script in normal and expert mode
#packmode normal import crafttweaker.items.IItemStack; print("If I appear on your CT-logs, packmode normal is enabled!");
What it does
The Processor will only allow the script to be executed if a certain packmode is enabled.
