What's the difference between our http://tex.stackexchange.com/q/142540/1340 and http://tex.aspcode.net/view/635399273629833626247972/configuring-latexmk-to-use-a-preprocessor? I see none, and http://tex.aspcode.net/ seems to just have copies of some (not all) questions. Yet, Google prefers this other website to ours if I google `synctex preprocessors`. Should somebody take action? Apologies if meta is the wrong place for such reports.
