149 Your current lilalo context is ${lilalo_context}/USER

150 If you use xgu.ru backend, your labs will be available at

151 http://xgu.ru/l3/${lilalo_context}

152

153 Use commands

154 $ l3cd ${lilalo_context%/*/*}/MY-NEW-CONTEXT/${hostname}/USER

155 $ l3pwd

156 to change and to know your current context.
