What is the WoW UI Designer?

[BlackPanther]

What exactly *is* the WoW UI Designer? I've been looking through the forum & faq trying to find out but no success.
I don't really want to install some program without knowing what it does!^^
If there is some information on it which I overlooked I'd be happy if you pointed it out to me.
Thanks.

From the description on the download page, here:

This is the WoW UI Designer initially mentioned here (link long dead). It started off as an idea I had to be able to load in any addon frame and edit it like you would a form in Borland C++ Builder (my development environment of choice until recently). From that it developed into a full IDE, with the ability to edit lua scripts, and xml files in both code and designer views. Hopefully in the months ahead, it will develop into the only choice for WoW interface developers even if the visual designer is not powerful enough for them.
