Tapper::Reports::Receiver::Level2::Codespeed

=head1 SYNOPSIS

Used indirectly via L<Tapper::Reports::Receiver|Tapper::Reports::Receiver>.

 package Tapper::Reports::Receiver::Level2::Codespeed;

 sub submit
 {
        my ($util, $report, $options) = @_;
        # ... actual data forwarding here
 }

=head2 submit

Submit carved out data from a report to a Codespeed application URL.

=head1 NAME

Tapper::Reports::Receiver::Level2::Codespeed - Tapper - Level2 receiver plugin: Codespeed

=head1 ABOUT

I<Level 2 receivers> are other data receivers besides Tapper to
which data is forwarded when a report is arriving at the
Tapper::Reports::Receiver.

One example is Codespeed to track benchmark values.

By convention, for Codespeed the data is already prepared in the TAP
report like this:

 ok perlformance
   ---
   codespeed:
     -
       benchmark: Rx.regexes.fieldsplit1
       commitid: 1b1a3d2a
       environment: renormalist
       executable: perl-5.12.1-foo
       project: perl
       result_value: 2.58451795578003
     -
       benchmark: Rx.regexes.fieldsplit2
       commitid: 1b1a3d2b
       environment: renormalist
       executable: perl-5.12.1-foo
       project: perl
       result_value: 1.04680895805359
   ...
 ok some other TAP stuff

I.e., it requires a key C<codespeed:> containing an array of chunks
with keys that Codespeed is expecting.
