Here's what I did:
1. Make a file "trapper.pl". It's basically the same as the example,
except the Log4perl init, which uses a config file (in this case, with a
SIGHUP to re-read it):
########################################
package Trapper;
########################################
use Log::Log4perl qw(get_logger :levels);
Log::Log4perl->init_and_watch("../log4perl.conf",'HUP');
my $logger = get_logger("program.category");
sub TIEHANDLE {
... [etc]
2. In my perl program:
require "trapper.pl";
tie (*STDERR, 'Trapper');
HTH,
Rob
