Well, it is a binary package compiled against Qt 4.7 and the Lua
binaries found in LfW, so that's the naming. And about the size... Well,
Qt is a full-blown "runtime environment" for C++, with GUI, file,
networking and database support. And as I said elsewhere, the bindings
are unfortunately almost as big as the libraries themselves.

However, given today's disk capacities, it is a small price to pay for
the convenience...

My fault, I didn't update the Windows binaries, will do it later when I
have access to my Windows machine with Qt.

Well, I have written only a single "big" application with lqt, a "visual
language editor", where the visual language is based on Lua and
hypergraphs. The main thing used from Qt was the GraphicsView framework,
with a lot of drawing (custom graphics items and connectors), but it was
all relatively simple to do in Lua.

I read the official Qt book [1], which explains a lot of details about
Qt, but if you are looking for tutorials, you should see [2], and the
demos [3].
