NAME
    Parallel::ForkManager::Child - role adopted by forked Parallel::ForkManager processes

VERSION
    version 2.02

SYNOPSIS
       use 5.10.0;

       use Parallel::ForkManager;

       my $fm = Parallel::ForkManager->new;

       say "parent does not consume the child role: ", $fm->does('Parallel::ForkManager::Child');

       $fm->start_child(sub{
            sleep $_;
            say "but the child does: ", $fm->does('Parallel::ForkManager::Child');
            say "child $_ says hi!"

       }) for 1..3;

DESCRIPTION
    When the parent Parallel::ForkManager object forks a child process, its forked incarnation
    consumes this role. The role doesn't do much: it changes the returning values of "is_child" and
    "is_parent" in the way you'd expect, change "start" so that it'd die if called from within the
    child, and change the implementation of "finish" to potentially send data back to the parent
    process.
