Hello, in @node Minimum the Texinfo manual lists as valid file extensions .texinfo, .texi, .txi or .tex is this order and in the footnote states, that the longer extensions are preferred. This is a recommendation to use .texinfo. In the Automake manual .tex, .texinfo, .texi are accepted, but the former generate a warning. Please update the Texinfo manual to state, that when used with Automake the extension shall be .texi.
Please replace the link in @node GNU Sample Text “The version.texi file in the @include command is maintained automatically by Automake (*note (automake)Top::)” with *note (automake)Texinfo. The functionality of version.texi is described there. Automake defines in version.texi the variables VERSION, UPDATED and UPDATED-MONTH, but the Texinfo manual does not mention the last variable.
