Using the query file (and/or the declaration file, see 3.5), zdatrinf can be used in batch or UNIX pipe mode for sets of pre-defined queries, without manually entering them in the Zdatr 2.0 interactive command-line mode. In the current version, the query file is line oriented: each query has to be in one line. Comments are allowed as usual: starting with a '%' and ending at the next newline.
