NAME
       Log::Log4perl::Util::Semaphore - Easy to use semaphores

SYNOPSIS
           use Log::Log4perl::Util::Semaphore;
           my $sem = Log::Log4perl::Util::Semaphore->new( key => "abc" );

           $sem->semlock();
             # ... critical section
           $sem->semunlock();

           $sem->semset( uid  => (getpwnam("hugo"))[2],
                         gid  => 102,
                         mode => 0644
                       );

DESCRIPTION
       Log::Log4perl::Util::Semaphore provides the synchronisation mechanism
       for the Synchronized.pm appender in Log4perl, but can be used
       independently of Log4perl.

       As a convenience, the "uid" field accepts user names as well, which it
       translates into the corresponding uid by running "getpwnam".
