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

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

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

150

151 Use commands

152 $ l3cd ${lilalo_context%/*/*}/MY-NEW-CONTEXT/${hostname}/USER

153 $ l3pwd

154 to change and to know your current context.

155
