Almost two years ago I answered a question with a simple link to a library which seemed to help the questioner since my answer was accepted.
My answer keeps getting downvoted but no other good answers seems to be available.
I cannot downvote or delete my own answer.
It would probably be wrong to edit the answer and remove the link since it was accepted. I cannot really give any more value to the answer since this is certainty not my area of expertise, I was just trying to be helpful.
