       Log::Log4perl::Resurrector - Dark Magic to resurrect hidden L4p statements


       Loading "use Log::Log4perl::Resurrector" causes subsequently loaded modules to have their

           ###l4p use Log::Log4perl qw(:easy);

           ###l4p DEBUG(...)
           ###l4p INFO(...)

       statements uncommented and therefore 'resurrected', i.e. activated.

       This allows for a module "" to be written with Log4perl statements commented out
       and running at full speed in normal mode.  When loaded via

           use Foobar;

       all hidden Log4perl statements will be ignored.

       However, if a script loads the module "Foobar" after loading "Log::Log4perl::Resurrector",
       as in

           use Log::Log4perl::Resurrector;
           use Foobar;

       then "Log::Log4perl::Resurrector" will have put a source filter in place that will extract
       all hidden Log4perl statements in "Foobar" before "Foobar" actually gets loaded.

       Therefore, "Foobar" will then behave as if the

           ###l4p use Log::Log4perl qw(:easy);

           ###l4p DEBUG(...)
           ###l4p INFO(...)

       statements were actually written like

           use Log::Log4perl qw(:easy);


       and the module "Foobar" will indeed be Log4perl-enabled. Whether any activated Log4perl
       statement will actually trigger log messages, is up to the Log4perl configuration, of

       There's a startup cost to using "Log::Log4perl::Resurrector" (all subsequently loaded
       modules are examined) but once the compilation phase has finished, the perl program will
       run at full speed.

       Some of the techniques used in this module have been stolen from the "Acme::Incorporated"
       CPAN module, written by chromatic. Long live CPAN!
