PARAMETERS

DTD_FILE | STAT_FILE
	 File containing the DTD or statistics.

OUTPUT_FILE
	 Output file.

NUM_QUERIES
	 Number of queries to be generated.

MAX_QUERY_DEPTH
	 Maximum query depth.

PROB_WILDCARD
	 Probability of the wildcard occurrence in each location step.

PROB_DOUBLESLASH
	 Probability of the double-slash occurrence in each location step.

OPTIONS

--theta=REAL
	 Distribution of the child elements appearing inside a chosen element.
	 REAL is between 0 and 1: 0 - uniform distribution; 1 - skewed zipf distribution.

--num_predicates=NUM
	 Number of predicates per query.

--num_nestedpaths=NUM
	 Number of nested paths per query.

--prob_predicate=REAL
	 Probability of each possible predicate appearing in a query.

--prob_nestedpath=REAL
	 Probability of having a nested path in each location step.
