       The Debian project regards the full documentation  for  ifnames  to  be
       non-free,  so it is not included in Debian.  Nevertheless, the non-free
       distribution that accompanies Debian includes the manual in  its  auto‐
       conf-doc  package.   Otherwise,  you may be able to access the Autoconf
       manual online.
