+It is generally up-to-date with the latest LLVM release:
+ * The current version was updated in Summer 2020 and worked with the LLVM 10 at that time.
+ * Small changes have been made in 2021 to get it to work with LLVM 11.
+ * LLVM 12 was released in April 2021 (!) and this code has **not** been updated for it (yet),
+ since as of this writing, not even Arch Linux makes this available.
+ * However, **be warned**, this code will eventually be updated to LLVM 12!

- system (but not guarenteed to work outside Linux). Test files have also

Still, it should be emphasized that there is nothing really new here -- apart
from the packaging, everything here is from the LLVM project!

- (see http://www.llvm.org/docs/GettingStarted.html - or perhaps better,
