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

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

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

151

152 Use commands

153 $ l3cd ${lilalo_context%/*/*}/MY-NEW-CONTEXT/${hostname}/USER

154 $ l3pwd

155 to change and to know your current context.
