    @class wxFileConfig

    wxFileConfig implements wxConfigBase interface for
    storing and retrieving configuration information using plain text files. The
    files have a simple format reminiscent of Windows INI files with lines of the
    form @c "key = value" defining the keys and lines of special form
    @c "[group]" indicating the start of each group.

    This class is used by default for wxConfig on Unix platforms but may also be
    used explicitly if you want to use files and not the registry even under
    Windows.

        data is saved unconditionally, i.e. even if the object is not dirty. However
        after saving it successfully, the dirty flag is reset so no changes will be
        written back to the file this object is associated with until you change its
