[bug#56354] [PATCH] gnu: engineering: Add candle.

Hello,

I found out that the patch I've sent was broken in two ways: firstly, it
contains only part of my changes; secondly, Candle fails to store its
settings as it tries to store it in the same directory where the binary
stored.

Here's the updated patch.
