## NAME
    [Log::Log4perl::Config::PropertyConfigurator](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AConfig%3A%3APropertyConfigurator/markdown) - reads properties file

## SYNOPSIS
        # This class is used internally by [Log::Log4perl](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl/markdown)

        use [Log::Log4perl::Config::PropertyConfigurator](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AConfig%3A%3APropertyConfigurator/markdown);

        my $conf = [Log::Log4perl::Config::PropertyConfigurator](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AConfig%3A%3APropertyConfigurator/markdown)->new();
        $conf->file("l4p.conf");
        $conf->parse(); # will die() on error

        my $value = $conf->value("log4perl.appender.LOGFILE.filename");

        if(defined $value) {
            printf("The appender's file name is $value\n");
        } else {
            printf("The appender's file name is not defined.\n");
        }

## DESCRIPTION
    Initializes log4perl from a properties file, stuff like

        log4j.category.a.b.c.d = WARN, A1
        log4j.category.a.b = INFO, A1

    It also understands variable substitution, the following configuration
    is equivalent to the previous one:

        settings = WARN, A1
        log4j.category.a.b.c.d = ${settings}
        log4j.category.a.b = INFO, A1
