Option :: expose - Export option to environment variable
The function allows exporting an option value to the system environment of the process. This allows passing information to subsequent processes called from the current process. Exported options can be retrieved in subsequent processes by calling Option ::toString() , as option variable in OSI scripts ( % option_name % ) or as environment variable in shell procedures.
When the option has got a hierarchical name (e.g. sample.database ), the complete path is used as name for the environment variable.
