    % we are working with input and output structures, with some rules
    % embedded here

    % fields that are expected of the input and output structures
    %
    % id - uniquely defines a subject or subject/date
    % bp - base path
    % *_fn - filenames, will be checked if they exist
    %
    % in addition, it could have these field(s):
    %
    % tmp - temporary info, with fields
    %   bp - base path
    %   do_delete - determines whether the path will be deleted after
    %   execution
