Get rid of err.h as it is not portable Replace warn() and warnx() with fprintf() and add <stdio.h> where necessary. 2018-03-28 16:26:56 +00:00			`#include <stdio.h>`
Split into multiple files For multiple reasons the program is now split: - Make future porting to OpenBSD easier - Assign header includes to individiual functions - Make future program extensions easier - Recompile only changed parts 2017-09-17 14:18:17 +00:00			`#include <stdlib.h>`

Move components into dedicated subdirectory This brings us a lot more tidiness. 2017-09-24 13:33:01 +00:00			`#include "../util.h"`
