Emacs 29 comes with many manuals for Emacs features. There is the main manual, the Elisp manual, the Elisp intro, the FAQ and another 60 manuals.
There aren’t many info manuals for non-GNU apps. However, nearly every GNU package has an info manual. For GCC there is a manual for each language and so more. There are also manuals for grep, find, awk and many others.
Most Linux distros will have these on your system already. Some of them don’t such as Debian and Ubuntu. For those you have to do some setup to get them, but they can be accessed. Like Yegge, I have hundreds of them.
