Indeed, every "command" has a number of common options, including ".dir".

I see that the guide does specifically mention autoconf.dir, automake.dir, autoreconf.dir, and patch.dir, but it's a bit redundant to have to describe each one when the description is the same (though it's true that the default value is not the same for all of them).

As I've said for years, the whole guide needs to be thrown out and rewritten from scratch. :(
