# What is this awesome window manager?
**awesome** is a highly configurable, next generation framework window
manager for X. It is very fast, extensible and licensed under the
[GNU GPLv2 license](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html).
It is primarily targeted at power users, developers and any people dealing with
every day computing tasks and who want to have fine-grained control on their
graphical environment.

# Concepts
A window manager is probably one of the most used software applications in
your day-to-day tasks, along with your web browser, mail reader and text editor.
Power users and programmers have a big range of choice between several tools
for these day-to-day tasks. Some are heavily extensible and configurable.
**awesome** tries to complete these tools with what we miss: an extensible,
highly configurable window manager.
To achieve this goal, **awesome** has been designed as a framework window
manager.
It's extremely fast, small, dynamic and heavily extensible using the
[Lua](http://www.lua.org) programming language.
We provide a documented API to configure and define the behavior of your
window manager.

# Features and non-features
* Very stable, fast and small codebase and footprint.
* First window manager using the asynchronous [XCB](http://xcb.freedesktop.org)
library instead of the old, synchronous
[Xlib](http://en.wikipedia.org/wiki/Xlib), which makes **awesome** less
subject to latency compared to other window managers.
* Documented source code and API.
* No mouse needed: everything can be performed with the keyboard.
* Real multihead support (XRandR) with per screen desktops (tags).
* Implements many [Freedesktop](http://www.freedesktop.org) standards:
[EWMH](http://standards.freedesktop.org/wm-spec/wm-spec-latest.html),
[XDG Base Directory](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html),
[XEmbed](http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html),
[Desktop Notification](http://www.galago-project.org/specs/notification/),
[System Tray](http://standards.freedesktop.org/systemtray-spec/systemtray-spec-latest.html).
* Does not distinguish between layers: there is no floating or tiled layer.
* Uses tags instead of workspaces: allow to place clients on several tags, and
display several tags at the same time.
* A lot of Lua extensions to add features: dynamic tagging, widget feeding,
tabs, layouts, …
* [D-Bus](http://dbus.freedesktop.org) support.
* And more.
This is gonna be LEGEN... wait for it... DARY!
