9. common::sense? - No utf8 until v3.0 - No open :utf8 support for v3.0+ - No require perl 5.10+ for features - No Carp - No mro

23. Daemond (github) - Correct daemonization - Detach - redirection of output - keeping the fileno for STD* handles - chroot - change user - Pluggable engine - Built-in CLI (Command-line interface) - Pidfile - Scoreboard - Different packages for child and parent - Child monitoring for parent death - Timers for termination
24. Simple Daemond package SampleD; use Daemond -parent; name 'test'; cli; # Command line control proc; # Alter $0 children 1; # How many children pid '/var/run/test.pid'; child { $SIG{USR2} = sub { exit; }; while() { do_job(); } };
25. Daemond CLI Usage: [options] [start|stop|restart|check] Options: -v, --verbose increase verbosity level -f, --nodetach run in nodetach mode -c N, --children N redefine count of children
