KNOWN BUGS

The --restart-time (-r) option is not implemented yet. However, the File::Tail
module makes it unnecessary for the most part. 

The File::Tail module does not use the input record separator that perl
recognizes. It is supposed to be implemented soon. You can get around this
problem by using the --read-pipe (-p) option 
(e.g. "swatch -p 'tail -f /var/log/syslog').

Signal handling is still buggy. Swatch will restart after the first HUP signal,
but will not restart again unless it receives a HUP then an INT.
