-Currently, only two types of data are supported: string and long (but it might

-casts. Better yet, just use {\it long} for all variables which you're going to
-save in the config file: chances are that {\tt sizeof(bool) == sizeof(int) == sizeof(long)} anyhow on your system. For {\it float}, {\it double} and, in
-general, any other type you'd have to translate them to/from string
-representation and use string functions.
