+VirtualMachine Chooser - plugin
+===============================
+
+This Plugin uses an additionally provided program to display a list of virtual
+machine sessions (vm's provided by other plugins), from which a user can choose.
+
+This Programm is included in binary format. You can look into the sources at 
+svn://svn.openslx.org/srv/svn/openslx/openslx-src-tools/os-plugins/plugins/vmchooser/
+
+There you can change the program to your needs and compile it with the included 
+Makefile.
+
+Additionally the plugin provides a script to start a specific virtual machine
+preconfigured. Parts of the configuration are taken from an xml file which 
+should be provided with each container file. You will find additional infor-
+mation online at: http://lab.openslx.org/wiki/openslx/Vmchooser
+
+Use at your own risk! No warranty is given by the author of this software for 
+any purposes!
