I appreciate these posts for "I just need to do X..." google-search-for-my-fix problems. But I've always found it frustrating that this is what the whole www is now: a whole lot of spread out individual docs for individual problems, rather than a concise review of useful information (a "just the useful bits" database if you will).
Try to learn anything in depth these days and either you're deciphering a dense yet incomplete manual, or googling until eternity. Make is a great example, as even though they have a useful manual, good luck figuring out how to apply it to your problem. Wikis don't quite cut it either. We need a different data model for knowledge sharing.
OK, but I wrote those things as "advanced" uses of make because the actual GNU Make Manual is very, very good (https://www.gnu.org/software/make/manual/) and people should read it.
I keep wondering about doing a video series explaining GNU Make from the ground up.
For those who don't know, here's a list of stuff I've written over the years.

PS I really like the layout of your blog.
