0.90.5 released.

EekGtkKeyboard is now a subclass of GtkWidget not EekKeyboard.  Widget
creation is done as follows:

layout = eek_xkl_layout_new (...);
keyboard = eek_keyboard_new (layout, 640, 480);
widget = eek_gtk_keyboard_new (keyboard);

Broken Clutter support is temporarily disabled.

-eekboard - a virtual keyboard for GNOME -*- outline -*-
+eekboard - an easy to use virtual keyboard toolkit -*- outline -*-
 
-eekboard is a virtual keyboard software package which ships with a
-standalone virtual keyboard application ("eekboard"), and a library to
-create keyboard-like UI ("libeek").
+eekboard is a virtual keyboard software package, including a set of
+tools to implement desktop virtual keyboards.
 
-* Requirements
+* How to build
 
-  * GLib2, GTK2, Cairo, Pango, Libxklavier...
-  * Clutter (optional)
-  * Clutter-Gtk (optional)
+** Dependencies
 
-* How to test
+REQUIRED: GLib2, GTK, GConf2, PangoCairo, libxklavier, libcroco
+OPTIONAL: fakekey, CSPI, Clutter, Clutter-Gtk, Vala, gobject-introspection
 
-If you build from git repo:
+** Build from git repo
 
   $ git clone git://github.com/ueno/eekboard.git
   $ cd eekboard
   $ ./autogen.sh --prefix=/usr --enable-gtk-doc
-
-Otherwise start from here:
-
-  $ ./configure
   $ make
   $ sudo make install
+
+** Build from tarball
+
+  $ ./configure --prefix=/usr
+  $ make
+  $ sudo make install
+
+* How to test
+
+eekboard currently includes 3 tools to implement your own virtual
+keyboard.
+
+** eekboard-server
+
+eekboard-server is a D-Bus server which is responsible for drawing
+interactive on-screen keyboards.  Since it has a D-Bus service
+activation entry, you will not need to start it manually, but you can
+do that with:
+
+  $ eekboard-server &
+
+** eekboard
+
+eekboard is a client of eekboard-server.  It listens desktop events
+(keyboard change, focus in/out, and keystroke) and generates key
+events when some keys are pressed on the on-screen keyboard.  It can
+be started with:
+
   $ eekboard
 
-*NOTE* some version combination of Clutter & Clutter-Gtk does not
-cooperate well.  Try "EEKBOARD_DISABLE_CLUTTER=1 eekboard"
+** eekboard-xml
+
+eekboard-xml is a tool to manipulate XML keyboard description used by
+eekboard-client tool and in the eekboard library.
+
+To dump the current system keyboard layout into an XML file:
+
+  $ eekboard-xml --dump > keyboard.xml
+
+You can display the dumped layout with:
+
+  $ eekboard-xml --load keyboard.xml
+
+* Documentation
+
+See file:docs/reference/eek/html/index.html
