Thank you for the reply. :-)
Yes, I read that.

That code doesn't work on my system:
2011-01-30 14:08:11 dpchrist@p43400e ~/sandbox
$ cat log4perl-helper.pl
#!/usr/bin/perl
package Helper;
BEGIN {
Log::Log4perl->wrapper_register(__PACKAGE__);
};
use Log::Log4perl qw(:easy);
2011-01-30 14:08:16 dpchrist@p43400e ~/sandbox
$ perl log4perl-helper.pl
Can't locate object method "wrapper_register" via package
"Log::Log4perl" (perhaps you forgot to load "Log::Log4perl"?) at
log4perl-helper.pl line 4.
BEGIN failed--compilation aborted at log4perl-helper.pl line 5.
Putting the 'use' statement before the 'BEGIN' statement makes Perl
happy, but %c still shows the Helper package, not 'main':
2011-01-30 14:22:44 dpchrist@p43400e ~/sandbox
$ nl log4perl-helper2.pl
1 #!/usr/bin/perl
2 package Helper;
3 use Log::Log4perl qw(:easy);
4 BEGIN {
5 Log::Log4perl->wrapper_register(__PACKAGE__);
6 };
7 sub help { DEBUG(__FILE__, __LINE__, ' ', @_) }
8 package main;
9 use Log::Log4perl qw(:easy);
10 Log::Log4perl->easy_init({layout=>'%c %m %n'});
11 DEBUG(__FILE__, __LINE__);
12 Helper::help(__FILE__, __LINE__);
2011-01-30 14:23:00 dpchrist@p43400e ~/sandbox
$ perl log4perl-helper2.pl
main log4perl-helper2.pl11
Helper log4perl-helper2.pl7 log4perl-helper2.pl12
Any suggestions?
