I'd log it to a file and be sure to include pid. Then a simple file tail or grep on the pid would reveal the arguments:

use strict;
use warnings;

use Getopt::Long;
use Log::Dispatch::FileRotate;
use Log::Log4perl;

my $conf = q(
  log4perl.category.foo = DEBUG, FileRotateAppender
  log4perl.appender.FileRotateAppender           = Log::Dispatch::File
+Rotate
  log4perl.appender.FileRotateAppender.filename  = 667540.log
  log4perl.appender.FileRotateAppender.mode      = append
  log4perl.appender.FileRotateAppender.size      = 10000
  log4perl.appender.FileRotateAppender.max       = 5
  log4perl.appender.FileRotateAppender.layout    = PatternLayout
  log4perl.appender.FileRotateAppender.layout.ConversionPattern=[%P] %
+d %M %F:%L: %m%n
);
Log::Log4perl::init( \$conf );
my $log = Log::Log4perl::get_logger("foo");

my $man = undef;
my $woman = undef;

GetOptions(
  'man'   => \$man,
  'woman' => \$woman,
) or die(qq{Usage: $0 [--man] [--woman]});

# Set explicit to 0 or 1
$man   = ($man)   ? 1 : 0;
$woman = ($woman) ? 1 : 0;

$log->info(qq{man=$man}) if $log->is_info();
$log->info(qq{woman=$woman}) if $log->is_info();

# ------ main ------

# then do deamon stuff
