content from stdout:

=== Data for post analysis generated by BenchKit (invocation template)

The expected result is a vector of booleans
BOOL_VECTOR

here is the order used to build the result vector(from text file)

Working with output stream class java.io.PrintStream
Flatten gal took : 39 ms
Constant places removed 25 places and 0 transitions.
Iterating post reduction 0 with 25 rules applied. Total rules applied 25 place count 28 transition count 25
Applied a total of 25 rules in 4 ms. Remains 28 /53 variables (removed 25) and now considering 25/25 (removed 0) transitions.
