Use ISO-date-format in manpages The one specified by mdoc is hard to read for non-native speakers from countries which read the date day-first (like Germany, Greece, North-Korea, Swamp,...). This is also consistent with how we generally specify dates at suckless.org. 2015-10-08 15:15:08 +00:00			`.Dd 2015-10-08`

POSIX 2013 audit Mostly manpage-shuffling according to the changes in the corrigendum, wording changes and more idiomatic expressions. All this is finished up by marking the POSIX 2013 conformant tools with .St -p1003.1-2013 which is not available in older mandoc builds or nroff, but which reflects what we actually did, so who cares? This is a huge step and it's not far until we can release sbase 0.1. 2015-03-27 16:22:48 +00:00			`.St -p1003.1-2013`
