I have a very complex PERL script that I use for my radio station (plug away: http://ourthing.radio.binary9.net). Everytime I make a modification to my main "playdaemon" script, I have to kill it and restart it; which causes a hiccup in the stream (and restarts the current song).

What I would like to do is something like this (non-functioning): 

playdaemon:

#!/usr/bin/perl

require "MyRoutines.pl";

$SIG{HUP}=sub { require "MyRoutines.pl"; };

while (1) {
   DoIt();
}
__END__
Then, as I change the contents of MyRoutines.pl, I could send a SIGHUP to my program and it would reload the contents of MyRoutines.pl to reflect the changes.

Is such a thing possible? I believe my problem is that PERL already knows it has loaded the MyRoutines.pl library and won't do so again. How many I accomplish this?

TIA!
