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`

add some mandoc pages and fix some warnings - add .Os, it is mandatory. - don't redeclare .Nm when it's not needed. - fix some warnings (checked with mandoc -Tlint). - remove some leftover old stuff. 2015-01-30 20:17:58 +00:00			`.Nm`

Audit env(1) 1) Shorten synopsis and reflect this in the manual 2) Use argv0 in usage() 3) Decrement argc in argv-loop for consistency 4) Make it clearer which error-code results from which errno in enprintf 5) Use idiomatic for-loop also for environ. Don't increment these pointers in the loop itself! 2015-03-02 13:50:43 +00:00			`.Oo Fl u Ar var Oc ...`

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`
