Summary: A module to manage process id files

Description:
This Perl module is useful for writers of daemons and other processes that
need to tell whether they are already running, in order to prevent multiple
process instances. The module accomplishes this via *nix-style _pidfiles_,
which are files that store a process identifier.

The module provides two interfaces: 1) a simple call, and 2) an
object-oriented interface
