Anacron for Debian
------------------

Anacron runs transparently to the system.  In other words, you should
never be aware that anacron and not cron is actually running
cron.{daily,weekly,monthly}.

Anacron itself however is not a daemon, so it will either be called at
startup, on APM power status change, or by cron.  Disabling those will
result in some jobs not being executed on time.

Anacron leaves messages in /var/log/syslog and /var/log/messages by
default.

By default, anacron does not run while on battery power.  See
/etc/default/anacron to change that.
