=head1 NAME

Tapper::TAP::Harness - Tapper - Tapper specific TAP handling

=head2 tap_single_plan

Return true when TAP contains exactly one plan

=head2 fix_last_ok

The C<prove> tool adds an annoying last summary line, cut that away.

=head2 fix_section_names

Create sensible section names that fit further processing,
eg. substitute whitespace by dashes, fill missing names, etc.

=head2 evaluate_report

Actually evaluate the content of the incoming report by parsing it,
aggregate the sections and extract contained meta information.

=head2 generate_html

Render TAP through TAP::Formatter::HTML and fix some formatting to fit
into Tapper.
