contrib/perldoc-all/perldoc-all.texi says: "The output [of a translation of Perl documentation to texinfo] is available at http://www.gnu.org/software/perl/manual";.
This statement also appears at https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Invoking-pod2texi.html The cited web page does not currently exist (404 error). Changing the perldoc-all.texi file would of course be the easiest solution. (Updating the documentation on www.gnu.org would be nice if anyone were inclined to do the work.)
