=head1 DESCRIPTION

A wrapper around Devel::Cover, configuring some things to enable covering some
things default D::C misses, and to make it less noisy. Run this to generate a
coverage report on the tests:

    cover -delete && HARNESS_PERL_SWITCHES='-Ilib -MACover' prove -r t && cover

=cut

# prevent these two from interfering with coverage
BEGIN { $INC{$_}++ for qw( DB/Skip.pm UDAG/VendorBox/Log/Auto.pm ) }

#use Devel::Cover qw' -ignore ^t/ -coverage statement branch condition path subroutine ';

# this is for the sketched pushmark/leaveasync cover fixes below
# use Module::Runtime 'use_module';
# our $IS_ASYNC = 0;

# this silences warnings about some dynamically generated code
#no warnings 'uninitialized';
