Missing documentation for "Mod Maker Utility" from mod-loader plugin

[CarpeDiemKopi]

The tiddler for the link Mod Maker Utility is missing.

Is it the one to call from the patchmaker tab?

What exactly do I have to enter in Source? What do you mean by Source?

What exactly do I have to enter in Destination? What do you mean by Destination?

Why don't I get the cross in the destination line changed to a green tick? What are the requirements for this? What do you mean by "... will always be selected as a real tiddler"? I don't want to let any of these (plugin-) tiddlers found by standard search, so everyone has to begin with "$".

What exactly do I have to enter in Output?

What does target in error messages mean? What is the difference between target and destination? How do I tell the plugin which JavaScript file to patch?

The above hints under patchmaker are incomprehensible and/or incomplete.

The first time a result with these settings, but they don't make sense:
