Creating new Qleverfile ...
There was no "Qleverfile" in this directory yet, so I created one for you. A
Qleverfile contains basic configuration telling the "qlever" command how to do
certain things. Please check and modify as you see fit.
Checking .settings.json file ...
The index builder currently also requires a file "must_specify.settings.json", and I
created an empty one for you. In this file, you can specify specialized settings
for the indexer, for example: prefixes of IRIs for which the names are stored on
disk (to save RAM), the locale by which literals are sorted, the batch size used
by the indexer (default: 10M), and whether the input is well behaved in a
certain way (which enables faster indexing). See the QLever Wiki for more
information.
Setup is complete
Type "qlever" and use autocompletion to see which actions are available. Add a
"show" in the end to see what an action does without executing it (for example,
"qlever index show"). Typing "qlever" without arguments gives some basic help
and pointers for further help. Edit your local "Qleverfile" to change settings.
