The Free Format Section

The last section in the control file is optional and in a ``free format'' which works as follows: each line in the free format sections starts with a keyword written in capital letters followed by a listof space or tabulator separated parameters. The order of keywords in that section does not matter. There is also the possibility to use comments. Comment lines start with `!' or with `#'. Additionally the C comment style using `/*' and '*/' can be used.
