    use JIP::Daemon;

    my $proc = JIP::Daemon->new;

    # Send program to backgroung.
    $proc = $proc->daemonize;

    # In the backgroung process:
    $proc->is_detached; # 1
    $proc->try_kill(0); # 1
    printf qq{pid(%s), is_alive(%d), is_detached(%d)\n}, $proc->status;

    # If the program is already a running background job, the daemonize method shall have no effect.
    $proc = $proc->daemonize;

Dry run:

    use JIP::Daemon;

    my $proc = JIP::Daemon->new(dry_run => 1);

=head2 drop_privileges

    my $proc = JIP::Daemon->new(uid => 1000, gid => 1000, umask => 0, cwd => q{/});
    $proc = $proc->drop_privileges;

Change C<uid>/C<gid>/C<umask>/C<cwd> on demand.

=head2 try_kill

    my $is_alive = $proc->try_kill(0);

This is identical to Perl's builtin C<kill()> function for sending signals to processes (often to terminate them).

=head2 change_program_name

    my $proc = JIP::Daemon->new(program_name => 'tratata');
    $proc = $proc->change_program_name;

Changes the name of the program.

=head2 status

    my ($pid, $is_alive, $is_detached) = $proc->status;

Returns a list of process attributes: PID, is alive, is detached (in backgroung).

=head1 DIAGNOSTICS

None.

=head1 CONFIGURATION AND ENVIRONMENT

C<JIP::Daemon> requires no configuration files or environment variables.
