##@brief Lodel2 loader script
#
#@note If you want to avoid settings loading you can set the environment
#variable LODEL2_NO_SETTINGS_LOAD (see @ref install.lodel_admin.update_plugin_discover_cache()
#
# @note In tests case, you can pass the path to write results file, context_tests.log 
# It has to be at first, otherwise it will not be taken 
# and the default one, current directory, will be used.
