needrestart checks which daemons need to be restarted after library upgrades. It is inspired by checkrestart from the debian-goodies package. There are some hook scripts in the ex/ directory (to be used with apt and dpkg. The scripts will call needrestart after any package installation/upgrades. needrestart should work on GNU/Linux. It has limited functionality on GNU/kFreeBSD since /proc//maps does not show removed file links.
