Can someone provide me withe the link that explains the function of this script. Thanks
Sorry for that.
We are preparing PDF with description for all functions, there will be a special tread for it when it will be done.
Problem is, that it is still under development - we updated to 0-7-34 just today, so documentation becames outdated almost daily.

Also some videos can be found at youtube.
Still an amazing addon after all that time, maybe you should make a dedicaced thread, at least so people become more aware of its existence (as there are lots of useful tools in it) and can find the latest version easily, i remember discovering it only by luck on reading a thread you posted a reference to it.
Interesting addon - some kind of manual/video will be nice to see what all tools can do.
is there any info on the tools. ive found a couple on youtube but there are so many tools. Most of them dont have a tooltip so its like russian roulette trying to find how it works 
+1 for dedicated thread
Paul please consider it. The development of the addon doesnt matter as we are already using it, and very often.
