=head1 NAME

AWS::Lambda::Bootstrap - the bootstrap script for AWS Lambda Custom Runtime.

=head1 SYNOPSIS

Save the following script as C<bootstrap>, and then zip it with your perl script.
Now, you can start using Perl in AWS Lambda!

    #!perl
    use strict;
    use warnings;
    use utf8;
    use AWS::Lambda::Bootstrap;

    bootstrap(@ARGV);

Pre-built Perl Runtime Layer includes the C<bootstrap> script.
So, if you use the Layer, no need to include the C<bootstrap> script into your zip.
See L<AWS::Lambda> for more details.

=head1 DESCRIPTION

The format of the handler is following.

    sub handle {
        my ($payload, $context) = @_;
        # handle the event here.
        my $result = {};
        return $result;
    }

C<$context> is an instance of L<AWS::Lambda::Context>.

        my ($payload, $context) = @_;
        return sub {

            my $writer = $responder->('application/json');
            $writer->write('{"foo": "bar"}');
            $writer->close;
