✅ This indexing attempt was successful.
see QLever/script as discussed in QLever Issue #562 for the script which makes reproducing this attempt easier.
see QLever Discussions for more details on this attempt series.
since the https://github.com/ad-freiburg/qlever-control now has an official "qlever" script we have rename the script that has the purpose to make the import attempts reproducible to qleverauto.
Beware of https://github.com/ad-freiburg/qlever-control/issues/4 - make sure ulimit -n is set!. This attempt had to be restarted since setting the value within a script did not work.
