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

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

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

147

148 Use commands

149 $ l3cd ${lilalo_context%/*/*}/MY-NEW-CONTEXT/${hostname}/USER

150 $ l3pwd

151 to change and to know your current context.
