Ok, found this on the Gearbox forums

Tool++ is a full GUI wrapper for tool.exe. It also has a default selection feature that allows you to select which command you want to goto first when you start up. And it also outputs everything to a editbox that tool.exe spits out, and also hides tool so you don't have as much clutter. he tool output editbox only gets updated when the command completes currently; but i wam trying to make it update everything theres new text to be shown. I hope this helps as much as HAE does
Couldn't find out anything more on the HAE a.k.a. HEK v1.02, but found a d/l for it.
