Format error messages properly Make use of strerror(errno) and format all errors equally: function ['parameters']: error message 2018-03-28 13:46:27 -04:00			`#include <errno.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 10:18:17 -04:00			`#include <sys/utsname.h>`
