=head1 NAME

IPC::Lockfile - run only one instance of a program at a time using flock

=head1 VERSION

version 0.04

=head1 SYNOPSIS

Just import the module:

    #!/usr/bin/env perl

    use IPC::Lockfile;

    ... # program code here

This will open a lock on the program file, avoiding the need for an external

lockfile. This elegant L for lockfiles was proposed by Mark Jason Dominus.

=head1 DESCRIPTION

C is a module for use with Perl programs when you only want one

instance of the script to run at a time. It uses C and should work if

run on an OS that supports C (e.g. Linux, BSD, OSX and Windows).

=head1 SEE ALSO

L for a PID-based solution that relies on signals and has a race

condition (not recommended).
