Hello monks of Perl Knowledge

I am facing a wierd issue with File::Tail, the cpan doc for this module says that It automatically detects and follows the file that are rotated, but I do not see that to be the case. Below is the snippet from my code

use File::Tail;

$file=File::Tail->new("/var/log/maillog");

while (defined($line=$file->read)) {
      print "$line";
}

After the file is rotated , I find that File::Tail stops reading the new rotated file.

Also it does not end which means that the loop is still active

I have to then kill and restart the script for it to again start reading the new rotated file

Could someone please point out where I may be faltering ?

Thanks in Advance
