[systemd-devel] [PATCH][V3] systemd-analyze: rewrite in C.
Simon Peeters
peeters.simon at gmail.com
Mon Feb 4 12:32:33 PST 2013
Written by Peeters Simon <peeters.simon at gmail.com>. Makefile stuff
and cleaned up a bit by Auke Kok <auke-jan.h.kok at intel.com>.
---
Fixed some stuff and dit some more cleanup.
This should just cover the same usage as the old systemd-analyze, but we can
add more functionality afterwards (systemctl dot, other output formats,...)
This is the rebased version as asked by William.
