This is Caboodle 0.4, a clone of Planarity[1].

The objective of the game is to arrange the balls on the screen so that no lines cross.

You can find Caboodle on the web from http://www.iki.fi/juri/caboodle/ .

It is for the GNOME[2] environment. It is written in OCaml[3] using
lablgtk2[4] and cairo-ocaml[5] which in turn use Gtk+[6] and Cairo[7].

The author of this software is Juri Pakaste <juri@iki.fi>, and it is
licensed under the terms of the GNU General Public License, version 2
or newer. For more information, see COPYING.

To compile and install, run make install in the top level directory.
By default, Caboodle is installed under /usr/local. To install to an 
alternative location, you can define the make variables PREFIX. 

make PREFIX=/opt/caboodle install

If you do not wish for the .desktop file to go under
PREFIX/share/applications, you can define the variable DESKTOPLOCATION
separately.
