    20 The {{{main.cfg}}} file contains metadata informations about the identification and provider but also some important settings. The file is composed of various sections, namely {{{main}}}, {{{identification}}} and {{{provider}}} per default. Obviously, you are free to add new sections to the file if you need them for a specific Service. Nevertheless, you have to know that the {{{env}}} section name is used in a specific way. It lets you define environment variables that your Service requires during its runtime. For instance, if your Service requires to access to a X server running on framebuffer, you can add {{{DISPLAY=:1}}} line in your env section to take this specificity into account. As for the {{{env}}} section there is another section {{{lenv}}} where specific informations about status informations of a running Service will be written by the ZOO Kernel. For instance, when you service failed, you can set the value for {{{message}}}  in {{{lenv}}} to see it displayed in the {{{Status}}} node of the {{{ExecuteResponse}}}. If your process will take long time and can get informations about processing status, you can set a value between 0 and 100 to {{{status}}} in {{{lenv}}} to represent the percentage completed of the running Service.
