Externally generated pages ========================== A few pages come from external sources. Fixes to the pages should really go to the upstream source. tzfile(5), zdump(8), and zic(8) come from the tz project (https://www.iana.org/time-zones). bpf-helpers(7) is autogenerated from the kernel sources using scripts. See man-pages commits 53666f6c3 and 19c7f7839 for details.
