WHAT IS IT ========== This is a module to manage Unix PID files, which are files that store process identifier. A script (usually a daemon) can create a PID file to check whether it is already running, so it can avoid creating multiple instances of itself. HOW TO INSTALL ============== Just type: perl Makefile.PL make make test make install and you should be all set. HOW TO USE ========== For the usage, please consult POD document embedded in the library. Also, perldoc Proc::PID_File should show you the document if installed correctly.
