One way to register new manuals is by calling
`info-lookup-maybe-add-help' to register a new help
specification. Here's how info-lookup recognizes Tramp symbols from
Emacs Lisp buffers, for example:
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=99ad65eda44e3b6edcc51cf0fb70ea499c3ccb07

If you are not in an Emacs Lisp buffer, you can always do C-u C-h S and
select `tramp-info-lookup-mode' manually.
