21.1.1 makeinfo Advantages

The makeinfo utility creates an Info file from a Texinfo source providing better error messages than either of the Emacs formatting commands. We recommend it. The makeinfo program is independent of Emacs. You can run makeinfo in any of three ways: from an operating system shell, from a shell inside Emacs, or by typing the C-c C-m C-r or the C-c C-m C-b command in Texinfo mode in Emacs.

The texinfo-format-region and the texinfo-format-buffer commands may be useful if you cannot run makeinfo.
