Users may partition parameters specified by configuration file and put different groups into separate files. These files are inserted into the main file using constructs `@file`. Relative file names in it are resolved relative to the including configuration file and this is not convenient in some cases. A configuration file, which resides in system directory, may need to include a file with user-defined parameters and still provide default definitions if such file is absent. To solve such problems, the option `--config=` is allowed inside configuration files. Like `@file` it results in insertion of command-line arguments but the algorithm of file search is different and allows overriding system definitions with user ones.
