For more information and downloads, please consultWhat is Enlightenment?
Enlightenment is not just a window manager for Linux/X11 and others, but also a whole suite of libraries to help you create beautiful user interfaces with much less work than doing it the old fashioned way and fighting with traditional toolkits, not to mention a traditional window manager. It covers uses from small mobile devices like phones all the way to powerful multi-core desktops (which are the primary development environment).
Building Blocks
Enlightenment, the window manager is built on top of building blocks known as EFL (the Enlightenment Foundation Libraries).

I know that there are some SlackBuilds available on Slackbuilds.org, but they seem to be outdated.
I would really appreciate having that nice Desktop available for Salix
I can not build all those packages for my own due to I only have my crappy laptop with me here in Copenhagen.
Because I tried already the latest snapshot on Fedora with their packages, I can only recommend that new and very nice piece of software.
EDIT:
My idea was to just put all core libraries for EFL into only one package.
But it is difficult to handle with SLKBUILD, you have to tweak pkg-config, search pathes for headers and linker files.
The shell could be one package for its own and maybe also a themes package available.
